Description

  It relates to a server that delivers mail to specific members. In particular, the present invention relates to a server that distributes mail to members registered in a mailing list.

  There is a mailing list service that uses the Internet's e-mail function to deliver (broadcast) the same e-mail to multiple members. The mailing list service is a service suitable for communicating a topic common to members registered in the mailing list (see, for example, Patent Document 1).

Japanese Patent Application No. 9-306893

  Once, in Japan, every community had a “mutual aid system” within the community. In other words, “reciprocal assistance” such as “calling and responding” such as helping, sending, picking up, seeing safety, bulk buying of bargains, etc. exchanged between neighbors and neighbors without a barrier Existed, but today it has completely declined as the times changed. On the other hand, communication means such as personal computers, mobile phones and smartphones have been widely developed. In addition, mailing list services using such communication means have become widespread. By adding new functions to this mailing list, there is a possibility that the conventional “mutual assistance system” can be revived in a form that is more modern.

  Further, the conventional mailing list has the following problems from the standpoint of members who use the mailing list.

  The contents of sent and received emails may not be communicated well enough. For example, there may be cases where the overall picture is unknown, such as who is interested in the email being sent and received, what information is desired to be communicated by email. In addition, it may be difficult to understand how far a decision has been made when something is determined as mail transmission / reception is repeated.

  In addition, as the number of emails sent and received increases, it is often unclear who is the story leader. Leaders tend to be absent as members refrain from each other or rely on others to do something. In addition, the leader may have changed over time.

  Moreover, even if mail transmission / reception is repeated, the talk may not be completed or the story may be derailed. For this reason, the mail title and the content of the mail text may be different. Furthermore, the sense of deadline management that must be decided is thin, and the response to deadlines such as ordering goods is slow. Furthermore, in the case of calls for service activities or joint purchases, it is often the case that everyone will not respond unless the details are explained in order from the beginning. In other words, the conventional mailing list has a flawed mechanism that tends to be a “community of people” without a leader.

  Conventional mailing lists have the following problems from the standpoint of software service providers that provide mailing list services.

  It is difficult to extract information such as product consumption demand and purchase information from the contents of emails sent and received between members registered on the mailing list. In addition, I do not know who is the leader on each topic. I do not know if the conclusion has been decided or not. For this reason, it is difficult for software service providers to accurately and timely provide advertisement information related to products and services that are common interests among mailing list members to mailing list members.

  Some also analyze the body of an email. In recent years, analysis methods have been improved, and it has become possible to analyze the contents of emails with high accuracy. However, it is not always possible to accurately analyze various topics. In addition, the number of mail transmission / reception is enormous, and it takes a lot of time and a system to analyze them and extract information such as consumption demand and purchase information.

  The present invention has been made in view of the above-mentioned points, and the purpose of the present invention is to provide a “mutual assistance mechanism” that allows members who use the mailing list to easily exercise leadership, call, respond, and make decisions. And providing a mail delivery server that enables a software service provider that provides a mailing list service to easily grasp the contents of the mail and send appropriate advertisements to members of the mailing list.

An embodiment of the mail delivery server according to the present invention is as follows:
Destination storage means for storing the destinations of members registered in the mailing list;
Option storage means for storing project proposal information pre-assigned to each of a plurality of options;
A mail generation means for generating a project mail for informing a member of a proposed project, and generating a project mail based on project proposal information assigned to at least one option selected from the plurality of options by one member Email generation means to
Project mail delivery means for delivering the project mail to members;
An advertisement storage device for storing a plurality of advertisement information;
And an advertisement mail distribution means for selecting at least one advertisement information from the plurality of advertisement information based on project proposal information assigned to the at least one option and distributing an advertisement mail.

  According to the above-described configuration, since the project proposal information is assigned in advance to each of the plurality of options, the member registered in the mailing list can determine the contents of the project only by selecting the option.

  In addition, according to the above-described configuration, since the advertisement information is selected based on the project proposal information corresponding to the selected at least one option, consumption demands, purchase information, etc. of the products that are highly interested in the members registered in the mailing list Can be extracted, and an advertisement that accurately reflects the contents of the project mail delivered to the members can be extracted.

  It is possible to provide a mail delivery server that can easily grasp the contents of an email and send an appropriate advertisement.

<<<<< Overview of the present embodiment >>>>
Mailing lists are used by various groups. Specifically, the mailing list is often used by a group of members having the same common points, for example, members having a common purpose such as the same hobbies and qualification tests. In the following, for convenience, an example in which a plurality of members belonging to one group use the mailing list will be shown. Therefore, in the present embodiment, the members registered in the mailing list mean a plurality of members belonging to one group. Even when a plurality of groups use the mailing list service, even when there are members who belong to the plurality of groups in duplicate, the same processing can be performed.

  The mail delivery server according to the present embodiment provides a mailing list service and a website related to the mailing list service. That is, not only a service for sending and receiving mail between members but also various services for utilizing a mailing list are provided by a website.

  The mailing list service is a service that simultaneously distributes (broadcasts) e-mails to a plurality of people (a plurality of members). In the present embodiment, it is assumed that a software service provider provides a mailing list service.

  When one member registered on the mailing list is the founder and wants to propose a specific project to other members, first access the project recruitment website provided by the software service provider, From “Event / Exhibition / Meeting Information”, “Free Service / Help”, or “Product Joint Purchase / Reservation”.

  When the founder proposes to other members the recruitment guidance for participation in the "project" such as "free service / help each other" and "joint product purchase / reservation", information about the project is displayed on the screen of the founder's terminal device. Recruitment information can be created by selecting an option. Next, the mail generated based on the created recruitment guide is distributed to the members of the mailing list all at once (broadcast), and the participants are recruited.

  Those who wish to participate in the project can access the bulletin board system (website) prepared on the software service provider's web server and select the information for application as an option. Register for an application. A link (such as a URL) for accessing the bulletin board system is described in an email distributed to members in order to invite participation in the project. The prosecutor can access the bulletin board system by a link described in the mail.

  The founder is the first person to suggest a project that he has come up with to a mailing list member. The founder can be a caretaker or a participant. Here, caretakers are members who act as organizers as project leaders. Caretakers are determined for each project. Participants are those who agree to participate in the proposed project.

  As described above, the founder may be a caretaker or a participant, and the founder need not necessarily be a caretaker. The case where the founder becomes a caretaker is a case where he / she becomes a leader while proposing a project. The case where the initiator becomes a participant is a case where a leader is assigned to another member while proposing a project.

  Whether the founder is a caretaker or a participant can be selected by the founder himself. If the founder is a caretaker, the participant is recruited as a founder. If the founder is a participant, the caretaker is recruited as a founder.

  Thus, by allowing each member to determine the role in the project, the roles of the caretaker and the participant in the “project” can be determined quickly and clearly.

The approximate process from project proposal to project execution decision is as follows.
1. A person who proposes a project accesses a project recruitment website provided by a software service provider, and inputs necessary information in a column such as “project overview” displayed on a project recruitment screen (described later).
2. Determine the project leader ("caretaker"). A member who wishes to become a leader becomes a “caretaker” by clicking a “caretaker” button displayed on a project recruitment screen or a project recruitment response screen (described later).
3. A person who wants to participate in the proposed project clicks the “Participant” button displayed on the project recruitment response screen and participates as a “participant”.
4). Members who are not interested in the project even if the email is delivered will not participate in the project.
5). The member who became the “caretaker” performs management from the decision of the project to the execution of the project.
6). When the “caretaker” clicks a “decision” button displayed on the project caretaker screen (described later), the execution of the project is decided, and the execution of the project is started.
7). Project proposals are basically made by “caretakers”, but even members who cannot become “caretakers” or members who do not want to be “caretakers” can propose projects.
8). A member who cannot become a "caretaker" or a member who does not want to become a "caretaker" becomes a "participant" by clicking the "participant" button displayed on the project recruitment screen, and proposes as a "participant" Fill in the “Project Summary” column. After that, a member who may read the contents of the “project overview” and take “caretaker” becomes “caretaker” by clicking the “caretaker” button displayed on the project recruitment response screen.

For example, there are personal computers and smartphones. The member terminal device 110 includes a CPU, a RAM, a ROM, an I / F, and the like.

<< Mail Delivery Server 200 >>
FIG. 2 is a functional block diagram showing an outline of the configuration of the mail delivery server 200. The mail delivery server 200 mainly includes a mailing list control unit, a project control unit, and an advertisement control unit.

  The mailing list control unit mainly includes a mailing list management unit and a mailing list storage unit.

  The mailing list management unit manages registration and deletion of members in the mailing list. Further, the mailing list management unit generates an email indicating notification of invitation to the mailing list for candidate members who wish to participate in the mailing list. In addition, the mailing list management section informs members that a new member has been added to the mailing list, informs that a member has left the mailing list, informs that the mailing list has been dissolved, and gives an error. Generate emails to be notified. The generated mail is distributed to the member terminal device 110.

  The mailing list storage unit stores members registered in the mailing list. For example, the member's destination (mail address), nickname, contact other than the destination, and the like are stored. When mail is distributed, the address stored in the mailing list is read and transmitted to the members registered in the mailing list. The mailing list storage unit is mainly composed of the RAM, ROM, and HDD of the mail delivery server 200.

  The project control unit mainly includes a project recruitment screen data storage unit, a project recruitment item storage unit, a project recruitment information analysis unit, a project recruitment email generation unit, a recruitment response website creation unit, and a project application information analysis. A project response mail generation unit, a project determination website creation unit, and a project determination unit.

  The project recruitment screen data storage unit stores project recruitment screen data used when the founder proposes a project recruitment. When a project recruitment screen request is transmitted from the member terminal device 110 of the initiator, the project recruitment screen data is read from the project recruitment screen data storage unit and transmitted to the member terminal device 110 of the initiator. This is used in steps T101, S201, T103, etc., which will be described later. The project recruitment screen data storage unit is mainly composed of the RAM, ROM, and HDD of the mail delivery server 200.

  The project recruitment item storage unit stores data of options used when the founder proposes a project recruitment. For input in the “role” column, data of options “caretaker” and “participant” is stored. For input in the "free service / help each other" column, "help / volunteer", "use / shopping agent", "pick-up / car sharing", "safety confirmation / emergency rescue", "manual input", etc. Choice data is stored. For input in the “Product Joint Purchase / Reservation” column, “Purchase of Goods / Food / Drinks”, “Travel / Accommodation Reservation”, “Party / Meal Reservation Reservation”, “Recreation / Leisure Reservation” and “Manual Input” Choice data is stored.

  The Project Recruitment Information Analysis Department has the “Role” column, “Event / Exhibition / Meeting” column, “Free Service / Help” column, “Commodity Joint Purchase / Reservation” column, and “Comment Entry” column. , Information entered in each of the “Product Name”, “Schedule Time”, “Location”, “Content”, and “Application Deadline Date” columns in the “Project Summary” column (hereinafter collectively referred to as “Project Recruitment Information”) ). When an option is input, the content associated with the option in advance becomes a keyword as it is. When a character is input, a keyword is extracted from the input character. The project recruitment information analysis unit is a process of extracting keywords from the project recruitment information. In the case of an option, the contents associated with the option in advance are directly used as keywords. For this reason, there is no need to process the document into words or the like, and the keyword can be determined immediately, thus simplifying the process. This is used in step S203 described later. The project recruitment information analysis unit is mainly configured by the CPU of the mail delivery server 200.

  Data processing (search, extraction, aggregation, analysis, etc.) of email information sent and received by members of the mailing list is performed by the project recruitment information analysis unit. By using the result of the data processing of the project solicitation information analysis unit, the advertisement control unit described later can extract product purchase information effective for advertising and sales promotion business.

  The project recruitment mail generation unit generates an email to be distributed to members registered in the mailing list from the analysis result of the project recruitment information analysis unit. For example, using a keyword determined or extracted by the project recruitment information analysis unit, a sentence is generated so as to be an email text or appearance. This is used in step S203 described later. The project recruitment mail generation unit is mainly configured by the CPU of the mail delivery server 200.

  The recruitment response website creation unit generates a recruitment response website for respondents to respond to project recruitment. The email generated by the project recruitment email generator is distributed to members registered on the mailing list. A member who is interested in reading the delivered mail becomes a founder and accesses the recruitment response website. By accessing the recruitment response website, the project recruitment response screen is displayed on the member terminal device 110 of the volunteer. The candidate can respond to the recruitment of the project by inputting various information (hereinafter collectively referred to as project response information) on the displayed project recruitment response screen. This is used in step S205 described later. The recruitment response website creation unit is mainly configured by the CPU of the mail delivery server 200. The project response information mainly includes information input in the “role” column and the “comment entry column” column.

  The project application information analysis unit is a process for extracting keywords from the project response information. As described above, the project application information analysis unit is mainly information input in the “role” column and the “comment entry column” column. In the case of an option, the contents associated with the option in advance are directly used as keywords. For this reason, there is no need to process the document into words or the like, and the keyword can be determined immediately, thus simplifying the process. This is used in step S207, which will be described later. The project recruitment information analysis unit is mainly configured by the CPU of the mail delivery server 200.

  The project response mail generation unit generates a mail for distribution to members registered in the mailing list from the analysis result of the project response information analysis unit. For example, using a keyword determined or extracted by the project response information analysis unit, a sentence is generated so as to be an email text or appearance. This is used in step S203 described later. The project response mail generation unit is mainly configured by the CPU of the mail delivery server 200.

  The project determination website creation unit generates a project determination website for the caretaker to determine execution of the project. The project decision website can be accessed by the caretaker member. An email indicating the project decision website is sent to the member who has selected “caretaker” in the “role” column displayed on the project recruitment screen or the project recruitment response screen.

  The project determination unit determines the execution of the project based on the operation of the “decision” button by the caretaker. As described above, a mail indicating the project decision website is transmitted to the member who has selected “caretaker”. When the “caretaker” accesses the project decision website, the project caretaker screen is displayed on the member terminal device 110 of the “caretaker”. A “OK” button is displayed on the project caretaker screen. The caretaker can decide to run the project by operating the “decision” button. The project determination unit is used in step S211 described later. The project determination unit is mainly configured by the CPU of the mail delivery server 200.

  The advertisement control unit includes an advertisement search device, an advertisement database, an advertisement mail generation unit, and an advertisement collection device.

  The advertisement database stores various pre-defined items in association with advertisements related to them. In particular, a configuration in which an advertisement can be determined by searching using a keyword is preferable. Various items include themes and topics common to mailing list members, such as travel, home purchases, cars, musical instruments, and restaurants. Furthermore, it is preferable to include information that is subdivided into regions and places for travel, and information that is subdivided into new buildings and used homes in addition to regions and places for homes. By including fragmented information, you can select ads that are closely related to your interests. The advertisement database is mainly composed of the RAM, ROM, and HDD of the mail delivery server 200.

  The advertisement search device searches an advertisement database using a keyword. The keyword can be determined from the project solicitation information entered on the project solicitation screen and the contents of emails sent and received between members of the mailing list. It should be possible to extract themes and topics that are common to members of the mailing list as keywords.

  The advertisement mail generation unit generates a mail including the advertisement determined by the advertisement search device. Specifically, using an advertisement determined by the advertisement search device, a sentence is generated so as to be a text or appearance of an email. This is used in step S223 described later. The project recruitment mail generation unit is mainly configured by the CPU of the mail delivery server 200.

  The advertisement collecting device collects advertisements from a trader who wants to provide advertisements. A trader who wants to provide an advertisement may register advertisement information in the mail delivery server 200, or a mailing list provider may contact a trader who wants to provide an advertisement to collect advertisements. In any case, it is only necessary to collect information that can be registered in the advertisement database with searchable information.

<< Process overview >>
An overview of the processing according to the present embodiment will be described with reference to FIG. As shown in FIG. 3, the process is performed between the member terminal device 110 and the mail delivery server 200. The processing roughly includes project recruitment and application processing and advertisement selection and transmission processing.

<Project recruitment and application>
First, a member who has come up with a project transmits a project recruitment screen request from the member terminal device 110 to the mail delivery server 200 as the originator (step T101). This process is executed by accessing a website provided by the mail delivery server 200 using a so-called web browser or the like.

  When receiving the project recruitment screen request, the mail delivery server 200 transmits data for the project recruitment screen to the member terminal device 110 of the initiator (step S201).

  Next, the initiator's member terminal device 110 receives the data for the project recruitment screen and displays the project recruitment screen (step T103).

  For example, the screen shown in FIG. 4A is displayed as a project recruitment screen on the member terminal device 110 of the initiator. The founder can enter each item on this project recruitment screen to clarify the contents of the project and recruit members to join the project.

  As shown in FIG. 4A, the project recruitment screen includes a “role” column, an “event / event / meeting guidance” column, a “free service / help each other” column, a “product joint purchase / reservation” column, The “Comment entry” and “Project overview” fields are displayed. In the “Project Summary”, columns of “Product Name”, “Schedule Time”, “Location”, “Content”, and “Application Deadline Date” are displayed.

  FIG. 4B is a diagram showing input in the “role” column. There are two types of “role”: “caretaker” and “participant”. When input is made in the “role” field, choices of “caretaker” and “participant” are displayed in a pull-down manner. The initiator can select either “caretaker” or “participant”. Thus, the input to the “role” column is a selection formula.

  The project is proposed by the founder. The initiator may be a caretaker or a participant. Whether the founder becomes a caretaker or a participant is determined by the founder himself selecting in the “Role” column.

  If the founder is a caretaker, the participant is recruited as a founder. If the founder is a participant, the caretaker will be recruited as a founder. In principle, there is only one caretaker, but depending on the project, there may be multiple people.

  The “Event / Exhibition / Meeting” column is not optional (not shown). The initiator can directly input characters by operating the keyboard of the member terminal device 110 or the like. For example, the name of the project can be entered in the “Event / Exhibition / Meeting Information” field. It is preferable to input contents that allow members to recognize the outline of the project.

  FIG. 5A is a drawing showing the input to the “free service / help each other” column. This column is a column for inputting specific contents belonging to “free service / help each other”.

  There are options for “Help / Volunteer”, “Use / Shopping Agent”, “Pick-up / Car Sharing”, “Safety Confirmation / First Aid”, “Manual Input”, etc. . When you enter in the column for “Free Service / Help”, the options for “Help / Volunteer”, “Use / Shopping Agent”, “Pick-up / Car Sharing”, “Safety Confirmation / Emergency Relief” and “Manual Input” are available. Pull down is displayed.

  The founder can select any one of “help / volunteer”, “use / shopping agent”, “pick-up / car sharing”, “safety confirmation / emergency relief”, or “manual input”. As described above, the input to the “free service / help each other” column is, in principle, a selection type, but there is also a “manual input”.

  When “manual input” is selected in the “free service / help each other” field, the input field shown in FIG. 5B is displayed in a pull-down manner. The initiator can directly input characters by operating the keyboard of the member terminal device 110 or the like. The founder can enter content that is not included in the choices in the "free service / help each other" field.

  FIG. 6A is a drawing showing input in the column of “commodity joint purchase / reservation”. This column is a column for inputting specific contents belonging to “commodity joint purchase / reservation”.

  In the “Product Joint Purchase / Reservation” column, there are options such as “Purchase of Goods / Food and Drink”, “Travel / Accommodation Reservation”, “Party / Meal Reservation Reservation”, “Pleasure / Leisure Reservation” and “Manual Input”. . When entering in the “Product Joint Purchase / Reservation” field, there are options for “Purchase of Goods / Food / Drinks”, “Travel / Accommodation Reservation”, “Party / Meal Meal Reservation”, “Pleasure / Leisure Reservation”, and “Manual Input”. Pull down is displayed.

  The initiator can select any one of “Purchase of goods / food / drinks”, “travel / accommodation reservation”, “party / meal meal reservation”, “excursion / leisure reservation”, and “manual input”. As described above, the input to the “commodity joint purchase / reservation” field is, in principle, a selection type, but also “manual input”.

  When “manual input” is selected in the “commodity joint purchase / reservation” field, the input field shown in FIG. 6B is displayed in a pull-down manner. The initiator can directly input characters by operating the keyboard of the member terminal device 110 or the like. The founder can enter contents that are not included in the options in the “Commodity Joint Purchase / Reservation” field.

  The comment entry field is not a selection type (not shown). The initiator can directly input characters by operating the keyboard of the member terminal device 110 or the like. For example, you can enter a message inviting you to the project or detailed information you want to convey to members in the comment box.

  The "Product Name", "Schedule Time", "Location", "Content", and "Application Deadline Date" fields in the project overview are not optional. The originator can input characters directly in these fields by operating the keyboard of the member terminal device 110 or the like.

  Note that the above-described options are examples, and other options can be used without being limited thereto. In particular, mailing list administrators analyze the words used in emails sent and received by members registered on the mailing list, and based on frequently used keywords, characteristic keywords, and keywords that are no longer used, The selection operation can be made easier to use by adding or changing options as appropriate.

  After the process of step T103 described above, the founder operates the member terminal device 110, so that the project recruitment information is input to each field displayed on the project recruitment screen described above, and the input project recruitment information is distributed by mail. To the server 200 (step T105).

  The mail delivery server 200 receives the project recruitment information transmitted from the member terminal device 110, generates an email for project recruitment based on the received project recruitment information, and delivers it to all members registered in the mailing list. (Step S203).

  The mail delivered to the member in the process of step S203 includes the project recruitment information transmitted from the member terminal device 110 and is shaped so as to be the text of the mail. Further, this e-mail includes information on a URL (Uniform Resource Locator) of a website for the respondent to respond to the recruitment of the project.

  In addition, the mail delivery server 200 stores the destinations (mail addresses, etc.) of members registered in the mailing list. The mail delivery server 200 reads the addresses of all the members and transmits the mail to all the addresses of the members registered in the mailing list. In this way, the process of step S203 is executed.

  The member terminal device 110 of the member registered in the mailing list receives the mail distributed from the mail distribution server 200 (step T107).

  By doing this, members registered on the mailing list know that one of the members has been recruited for some project.

  As described above, the mail delivered to the member includes the URL of the website for responding to the project recruitment. Members interested in the delivered mail project can access the website for responding to recruitment with a web browser as a provocate.

  When the prosecutor accesses a website for responding, a recruitment response website display request is transmitted to the mail delivery server 200 (step T109).

  When receiving the recruitment response website display request transmitted from the member terminal device 110, the mail delivery server 200 transmits data for the project recruitment response screen to the member terminal device 110 of the subject person (step S205).

  In addition, when the server 200 for mail delivery performs the process of step S203 mentioned above, the data for project recruitment response screens are produced | generated, and it will be in the state which can access a recruitment response website beforehand.

  The member terminal device 110 of the provocate receives the data for the project recruitment response screen and displays the project recruitment response screen (step T111). Thereby, a screen similar to FIG. 4A is displayed on the member terminal apparatus 110.

  In the project recruitment response screen, the founder can mainly operate the “role” and “comment entry” fields, and the contents are displayed in the fields other than “role” and “comment entry”. Just can't enter. It is preferable that the fields other than the “role” and the “comment entry column” can be changed only by the initiator and the caretaker in order to prevent confusion.

  On the project recruitment response screen, names of caretakers and participants determined at that time are displayed (for example, FIG. 7B, FIG. 8B, FIG. 9B, FIG. 10B, FIG. 11B, FIG. 12B, FIG. 13B and FIG. 14B). Here, the name does not have to be a real name, but may be a handle name or a nickname that members can recognize each other.

  As described above, there are two types of “role”: “caretaker” and “participant”. If the founder is a “caretaker”, the founder can respond by selecting “participant”. If the founder is a “participant”, the founder can respond by selecting “caretaker”. In the case where a plurality of “caretakers” may be used, even when the “caretaker” has already been determined, the provocate can select and respond to the “caretaker”.

  Further, the prosecutor can directly input characters in the “comment entry field” by operating the keyboard of the member terminal device 110 or the like. For example, it is possible to input a response to a project recruitment, additional information about the project, and the latest information.

  As described above, the project response information entered by the respondent in the “role” and “comment entry column” fields is transmitted to the mail delivery server 200 for the response to the project recruitment (step T113).

  The mail distribution server 200 receives the project response information transmitted from the member terminal device 110, generates a project response mail based on the received project response information, and distributes it to all members registered in the mailing list. (Step S207).

  The mail delivered to the member in the process of step S207 includes the project response information transmitted from the member terminal device 110, and is shaped so as to be the text of the mail.

  The member terminal device 110 of the member registered in the mailing list receives the mail distributed from the mail distribution server 200 (step T115).

  In this way, the founder can communicate his intention to the founder and other members in response to the recruitment of the project. On the other hand, the founder can recognize that one of the members has applied for the proposed project by receiving the delivered mail.

  In step S207 described above, every time there is an application from one of the members, an email indicating that there was an application and the contents entered in the “comment entry field” is distributed to all members registered in the mailing list. Is done. In this way, all members registered on the mailing list can recognize the status of responses to the project and accelerate the participation of the project.

  In this way, members registered in the mailing list can communicate with each other rather than presenting information unilaterally, and can exhibit a function as a mailing list.

  In addition, in accordance with the contents entered in the “role” and “comment entry field” fields entered by the respondent, the founder and the caretaker can change the contents of the project as appropriate. The initiator and caretaker can change each item of the project recruitment screen by transmitting a project recruitment screen request to the mail delivery server 200 in the same manner as in step T101. When the item is changed by the founder or the caretaker, the changed content and an email notifying that the item has been changed are delivered to the members. In this way, by changing the contents of the project according to the wishes of the founder, the hopes of the founder can be fed back to the founder and caretaker, and the contents of the project can be optimized to those desired by the members.

  The member who has become a caretaker through the above-described processing can determine whether or not to execute the project from the contents of the “role” and “comment entry field” input by the prosecutor and the delivered mail. The caretaker who has determined that the project can be executed transmits a project caretaker screen request from the member terminal device 110 to the mail delivery server 200 (step T117).

  When receiving the project caretaker screen request, the mail delivery server 200 transmits data for the project caretaker screen to the member terminal device 110 of the caretaker (step S209).

  Next, the caretaker member terminal device 110 receives the data for the project caretaker screen and displays the project caretaker screen (see FIG. 15) (step T119). Project recruitment information entered by the founder is also displayed on the project caretaker screen.

  The project caretaker screen is roughly the same as the project recruitment screen shown in FIG. 4, except that the names of the caretaker and participants and the “decision” button are displayed. Is different. The initiator and caretaker can recognize all the caretakers and participants at that time. The “OK” button will be described later.

  When the caretaker wishes to confirm the recruitment of the project, the caretaker operates the “decision” button (see FIG. 15) displayed on the project caretaker screen. When the caretaker operates the “decision” button, information indicating that the project has been decided is transmitted to the mail delivery server 200 (step T121).

  The mail delivery server 200 receives the information indicating the decision, and confirms the execution of the project (step S211).

  In this way, the caretaker operates the “decision” button to confirm that the project is to be executed. Note that the operation of the “decision” button of the caretaker is an operation for confirming the execution of the project, and does not complete the recruitment of the project. Therefore, even after the caretaker operates the “Determine” button, the call for projects continues.

  On the other hand, if the caretaker does not operate the “decision” button for a predetermined period, the execution of the project is in an unconfirmed state.

  Members registered in the mailing list may always send and receive emails with the same member terminal device 110, and even if they are different terminal devices, it is sufficient that they can send and receive emails with the destination registered in the mailing list.

<Ad selection and transmission>
The mail delivery server 200 analyzes the project recruitment information transmitted from the member terminal device 110 of the originator after executing the process of step S203 described above. Whether it is composed of members who are interested in travel, members who are interested in purchasing goods, members who are interested in cars or musical instruments, etc., in restaurants and other restaurants Matters common to the members constituting the mailing list, such as whether the members are interested in meals, are analyzed (step S221).

  Next, the mail delivery server 200 determines an advertisement from the analysis result of step S221 (step S223). The mail delivery server 200 stores advertisement information corresponding to the analysis result in advance. For example, a keyword that can be acquired from the analysis result is associated with the advertisement information, and is stored in a database in advance so that the advertisement information can be searched accurately and quickly from the keyword.

  Next, the mail distribution server 200 converts the determined advertisement into a mail and distributes it to all members registered in the mailing list (step S225).

  The mail is delivered to the member terminal device 110 of the member registered in the mailing list (T131).

  By doing in this way, it is possible to distribute an advertisement including contents that are of interest to the members constituting the mailing list. Instead of simply distributing all advertisements to a destination at random, information on contents of common interest is transmitted to members, so that it is easy to establish a commercial transaction based on the distributed advertisements.
