Description

METHOD FOR SENDING MASSIVE ELECTRONIC MAILS AT HIGH SPEED AND SYSTEM THEREOF

The present invention relates to an e-mail sending method and system and a computer-readable recording medium recording a program for implementing the method, and more particularly, to a mass e-mail sending method and system for e-mail marketing; A computer-readable recording medium having recorded thereon a program for implementing the method.

E-mail marketing is an interactive network marketing where product providers and customers communicate directly, one-to-many and many-to-many via e-mail, actively and in real time than traditional passive and costly offline marketing. Marketing techniques to get feedback.

Although many companies are attempting to implement internet marketing, they are still at the beginning level such as recruiting members from the company's homepage.As a more advanced marketing technique, two-way communication with consumers is possible. There is e-mail marketing that can facilitate this. If such email marketing is categorized by its contents, it can be divided into broadcast mail and individual mail. Broadcast mail refers to an e-mail in which all contents to be sent to multiple e-mail recipients are the same, and individual mail refers to e-mail in which all contents to different e-mail recipients are all different. For example, if a department store customer manager wants to e-mail a customer with information about a new product for this month, he or she would send the same new product information for this month by e-mail. do. On the other hand, if the department store customer manager manages the product or brand preference for each customer, and if the information about the brand and the product information are to be sent by e-mail, a separate content should be configured for each customer to be sent. These e-mails correspond to individual mails. Customer management through broadcast mail and individual mail has become an essential element in today's enterprises, and in almost all fields, such email marketing techniques are spreading.

On the other hand, in the prior art, the e-mail transmission / reception technique receives e-mail data generated from a mail user agent in a first-in first-out manner, and the e-mail sending agent accesses the e-mail receiving server in the order of received e-mail data. It is configured to transmit.

However, if a user wants to send a large amount of e-mail for e-mail marketing according to the prior art, since the e-mail sending agent accesses and sends the e-mail server for each e-mail data, the e-mail marketing agent sends the e-mail data to the receiving server for each e-mail data. There is a disadvantage in that the time to connect increases as the number of e-mail data increases. Also, if there are multiple e-mails to be sent to the same e-mail receiving server during one session, e-mail is sent on a first-in, first-out basis, so that e-mail addressed to the same receiving server is not received continuously at the sending server, Even during one session, the same receiving server is connected and transmitted for each e-mail, which takes a lot of time and a reduction in transmission efficiency. Furthermore, in the data process for sending an e-mail, the e-mail data received from the mail user agent is stored and read out of alignment, which results in a long time for searching for the stored file. This disadvantage becomes worse as more e-mails need to be sent.

Accordingly, the present invention has been proposed to solve the above-described problems, and a method for processing e-mail data to send a large amount of broadcast e-mails and individual e-mails at high speed, and dynamically sending and processing e-mails in parallel; It is an object of the present invention to provide a computer-readable recording medium having recorded thereon a program for realizing the system and the method.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a system for providing a mass mailing service according to an embodiment of the present invention. As shown in the figure, the present invention is implemented under an environment in which mass e-mail sending servers 1, e-mail receiving servers 3, 5, and 7 and e-mail recipient clients 9 are connected to a network such as the Internet. . For convenience of explanation, the names of the e-mail receiving servers 3, 5, and 7 are called mail.A.com, mail.B.com, and mail.C.com, respectively. The e-mail addresses of the e-mail recipient client 9 are referred to as Kim Il-young@A.com, Naseo@C.com, Park Chan-jin@B.com, and Kang Tae-seok@A.com, respectively. Assume that you are a bulk e-mail sender. Typically, an e-mail recipient is sent by an e-mail sending server that uses the SMTP protocol, received and stored on an e-mail receiving server that uses the POP3 protocol over a network, such as the Internet, and then has an account on the e-mail receiving server. The e-mail will be sent to the client.

2 is a block diagram showing the internal structure of a mass email sending system according to an embodiment of the present invention. As shown in the figure, the present invention provides a mail user agent 21 for generating a broadcast mail and an individual mail, a system manager 23 for grasping the transmission status of an e-mail, and a mass e-mail sending server 1 for transmitting e-mail. And a remote machine 2 that is remotely connected to the mass mailing server 1 and sends mass emails. The remote machine 2 is burdened by the e-mail sending server 1 by the user's choice when the amount of e-mails to be sent is so great that it takes a long time for the e-mail sending server 1 to process them alone. In order to share the load that is to be carried out, the e-mail server 1 is connected in parallel to perform an e-mail sending task.

The e-mail sending server 1 includes a receiving unit 25 which is responsible for receiving, storing and sorting e-mail data constituting substantial contents of the e-mail recipient information and e-mail generated from the mail user agent 21; In the broadcast mail unit 27 and the individual mail unit 29, the broadcast mail unit 27, and the individual mail unit 29 that receive data stored and sorted by the receiver 25 and perform data processing for high-speed transmission. The agent manager 31 dynamically manages the e-mail sending agent 41 which processes e-mail data in parallel to transmit e-mail at high speed based on the sorted recipient information and the e-mail data, which is transmitted from the mail user agent. File database (33) and remote machine (2) and file store for storing recipient information and e-mail data and data processed by e-mail sending server (1) It is composed of a file transfer unit 35 for transmitting and receiving data stored in the database (33). Although not shown, the receiver 25 includes a buffer memory and a main index queue, and the broadcast mail unit and the individual mail unit have sub index queues. The e-mail sending agent 41 performs a function of sending an e-mail by connecting to an e-mail receiving server 3, 5, 7 of a receiver to be sent.

In addition, the remote machine 2 performs data communication with the receiver 25 of the e-mail sending server 1, and the content data of the broadcast mail and the individual mail stored in the index data stored in the receiver 25 and the file database. The remote broadcast mail unit 37 and the remote individual mail unit 39 that perform data processing for high-speed sending by receiving data, and the recipients processed in the remote broadcast mail unit 37 and the remote individual mail unit 39. It consists of an agent management part 31 which dynamically manages the e-mail sending agent 41 which processes e-mail data in parallel in order to transmit e-mail at high speed based on information and e-mail data. The remote broadcast mail unit 37 and the remote individual mail unit 39 communicate data with the receiver 25 and the file transmitter 35 to read the recipient information and the e-mail content stored in the file database 33. Do this.

On the other hand, the broadcast mail unit 27, the individual mail unit 29, the remote broadcast mail unit 37, and the remote individual mail unit 39 are information and dispatch on the e-mail that has failed to be sent and sent by the e-mail sending agent 41. Information about the cause of the failure—for example, the number of e-mails you attempted to send, the number of e-mails that sent successfully, and the list of e-mails that failed to send, and the reason for the failed e-mail address is no longer valid. Or an e-mail sending result transmitter 57 that records the reason for the e-mail sending failure, such as the e-mail receiving server 3, 5, 7 does not respond, and the receiving unit 25 sends the e-mail. The result transmitter 57 includes an e-mail sending result receiver 55 which receives the sending result information stored in the result transmitter 57 and transmits it to the system manager 23 for display.

Hereinafter will be described an embodiment of the above-described procedure performed in the system according to the present invention and a data structure transmitted and received in the process.

3 is a flowchart illustrating an operation of the receiver of FIG. 2, and FIGS. 4A to 4E are structural diagrams illustrating data according to an operation flow of FIG. 3.

The receiver 25 stores the recipient information and the e-mail contents transmitted from the mail user agent 21, and performs the grouping and sorting operations described below for high speed shipment.

When the receiver 25 receives the recipient information and the e-mail data from the mail user agent 21 (1), the receiver 25 determines whether the received e-mail is a broadcast mail or an individual mail (S3). The format of the data received from the mail user agent 21 is that in the case of broadcast mail, all contents of the e-mail sent are the same, so that only one e-mail content may be received in the recipient e-mail address list. com; Naseo@C.com; Chanjin Park@B.com; Kang Taeseok@A.com; ...; Received in the form of 'e-mail contents', and in case of individual mails, since the contents of the e-mails to be sent are all different, the recipient e-mail address and the corresponding e-mail contents should be received.' Kim Il-young@A.com; E-mail content, Naseo@C.com; Email content, Chanjin Park@B.com; E-mail content, Kang Tae-seok@A.com; E-mail content, ... '. Therefore, the receiving unit 25 can determine whether the electronic mail to be sent is a broadcast mail or an individual mail only by the format of the received data.

If the format of the received e-mail is a broadcast mail, the receiving unit 25 stores the e-mail contents in a file format in a file database, and stores recipient information in a buffer memory (S5). The structure of the data stored in the buffer memory is shown in Fig. 4A. As shown in the figure, in the case of broadcast mail, the recipient information may be a recipient e-mail address as an embodiment of the present invention. Here, the buffer memory may be configured in plural, and in this case, sorting and grouping operations to be described later may be performed at a higher speed.

The receiver information stored in the buffer memory is sorted and grouped by the domains of the e-mail receiving servers 3, 5 and 7 (S7). The structure of the data grouped and stored in the buffer memory is shown in FIG. 4B, and as shown in FIG. 4A, the recipient e-mail addresses stored in FIG. 4A are grouped by domains of the e-mail receiving servers 3, 5 and 7. FIG.

Here, when the amount of e-mails to be sent is small, the grouping operation can be performed at high speed even with only one buffer memory. However, in the present invention to send a large amount of e-mails, a plurality of buffer memories are provided for the mail user agent ( 21) The receiver information received from the plurality of buffer memories is received and grouping is performed on the receiver information received for each buffer memory, thereby reducing the grouping execution time through load balancing of each buffer memory.

Subsequently, if it is possible to further store the receiver e-mail address by determining whether the receiver e-mail address is full in the buffer memory (S9), perform steps S5 and S7, and the receiver e-mail address is stored in the buffer memory. If filled, the recipient e-mail address stored in the buffer memory is stored in the file database 33 in the form of a file (S11), and information about the file is stored and indexed in the main index queue (S13). The index stored in the main index queue indicates a storage path of the file database 33 including a session ID for identifying a session for sending an e-mail and a file ID stored in the file database 33 as shown in FIG. 4C. Indicates. The index of this main index queue is used in the broadcast mail unit 27 as described later.

After step S13, the recipient e-mail address stored in the buffer memory is erased (S15), and it is determined whether all the broadcast mails to be sent are received from the mail user agent 21 (S17). The determination of whether the reception is completed is made by determining whether the electronic mail content is received from the data stream received from the mail user agent 21. As described above, in the case of the broadcast mail, since only one e-mail content is transmitted after the recipient e-mail address list is completed, when the e-mail content is received, it can be determined that all the data of the broadcast mail has been received. .

If all the broadcast mail data is not received, steps S5 to S17 are repeatedly performed. If all the broadcast mail data is received, the received e-mail contents are stored in the file database 33 in the form of a file ( S19). Here, the session ID is used as the storage information of the e-mail content of the broadcast mail. In the case of the broadcast mail, since one e-mail content is used for one session, the session ID can include the storage information of the file database 33 of the e-mail content.

As described above, when a plurality of buffer memories are provided, an operation speed of generating and storing index data in the main index queue is increased.

Hereinafter, the case of an individual mail will be described.

From the mail user agent 21, "Kim Il Young@A.com; E-mail content, Naseo@C.com; Email content, Chanjin Park@B.com; When it is determined that an individual mail is transmitted by being received in the form of e-mail content, Kang Tae-seok@A.com; e-mail content, ... ', the receiving unit 25 stores a file database in the form of a file for each e-mail data transmitted. 33) (S21). In other words, 'Kim Il-young@A.com; E-mail content ”,“ Naseo@C.com; E-mail content ”,“ Park Chan Jin@B.com; E-mail content, ”Kang Tae-seok@A.com; Each e-mail content is stored in a file format.

Subsequently, mail information is generated for each of the stored mail data (S23), and the generated mail information is stored in the buffer memory (S25). The data structure of the mail information stored in the buffer is shown in Fig. 4D, and as shown in the figure, the mail information is used to identify the session ID for sending the e-mail and the mail data stored in the file database 33. The storage path of the file database 33 including the file ID is shown.

Here, unlike the broadcast mail, the number of mail information stored in the buffer memory is determined by a user's selection. For example, the mail information stored in the buffer memory may be set in advance such that 600 mail information is stored in one buffer memory. This is for shortening the time for the individual mail unit 29 to search and read data stored in the file database 33 so that the e-mail can be sent at high speed. In addition, the buffer memory has a plurality of buffer memories in the present invention to send a large number of e-mails, as in the case of broadcast mail, and load buffers of each buffer memory by storing a plurality of buffer memories for mail information received from a mail user agent. This shortens the work time for creating and storing mail information in the main index queue.

As described above, the number of mail information stored in the buffer memory is compared with the preset number N (S27). When the number of mail information stored in the buffer memory is smaller than N, steps S21 to S27 are repeatedly performed, and the buffer If the number of mail information stored in the memory is N, the mail information stored in the buffer is stored in the file database 33 in the form of a file, and the information about the file is stored and indexed in the main index queue (S31). The index stored in the main index queue includes a session ID for identifying a session for sending an e-mail, a folder ID for identifying a file stored in the file database 33, and a mail stored in a folder, as shown in FIG. 4E. The storage path of the file database 33 including the range of information is shown. The index of this main index queue is used in the individual mail unit 29 as described later.

After step S31, the mail information stored in the buffer memory is erased (S33), and it is determined whether all individual mails to be sent are received from the mail user agent (S35). The determination of whether the reception is completed is made by simply determining whether the transmission of data from the mail user agent is completed.

If all the individual mail data has not been received, steps S21 to S35 are repeatedly performed, and if all the individual mail data have been received, the procedure in the receiver 25 ends.

5A to 5B are flowcharts illustrating operations of the broadcast mail unit, the individual mail unit, the agent manager and the agent of FIG. 2, and FIG. 6 is a structural diagram showing data stored in the sub index queue according to the flow of the broadcast mail of FIG. to be.

First, in the case of the broadcast mail, the broadcast mail unit 27 determines whether index data exists in the main index queue (S51), and if there is index data, there is a space for storing index data in the sub index queue. In operation S53, if space exists in the sub index queue, index data of FIG. 4C stored in the main index queue is sequentially received (S55). The recipient e-mail address stored in the file database 33 is read out based on the received index data (S57). That is, the recipient e-mail address is read by the file storage path of the index data. The recipient e-mail addresses read out here are grouped by domains of the e-mail receiving servers 3, 5 and 7, and the broadcast mail unit 27 stores these indexes in the sub index queue and indexes them. It performs (S59). Therefore, as shown in FIG. 6, the recipient index mail is stored in the sub index queue by domain. Based on the index data stored in the sub-index queue, the e-mail sending agent 41 sends an e-mail as described below, and after the sending is completed, the queue is deleted. Therefore, the existence of the index data continuously in the main index queue. It is determined from time to time whether the sub index queue is empty and the process proceeds so that the index data always exists in the sub index queue, so that the e-mail sending agent 41 performs the e-mail sending operation without interruption, thereby providing high speed e-mail. You will be able to send a large amount of.

As described above, the agent manager 31 determines whether there is an e-mail sending agent 41 in the idle state among the plurality of e-mail sending agents 41 each time the index data exists in the sub index queue (S61). (S63), if there is an idle e-mail sending agent 41, the e-mail content stored in the file database 33 is read out based on the message ID extracted from the index data read from the main index queue. (S65), the read e-mail contents are combined with the recipient e-mail address stored in the sub index queue (S67). Then, by activating the idle e-mail sending agent (S69), the e-mail sending agent connects to the e-mail receiving server based on the recipient e-mail address stored in the sub index queue (S71), and transmits the e-mail. (S73).

Here, the recipient e-mail addresses in the index data stored in the sub-index queue are grouped by the domains of the e-mail receiving servers 3, 5 and 7, and the e-mail sending agent 41 is activated for each index data and then e-mailed. Since the mail is sent out, the e-mail receiving server (3, 5, 7) is accessed only once and all the e-mails existing in one index data are sent out. You will be able to send e-mail.

In addition, the agent manager 31 manages the plurality of e-mail sending agents 41, and whenever the index data exists in the sub-index queue, activates the e-mail sending agent 41 in the idle state for each index data to perform e-mail. Since the e-mail sending agent 41 completes an e-mail sending operation for a specific index data, as long as there is index data other than the index data currently being processed by another e-mail sending agent 41, It is possible to perform dynamic processing for sending e-mails directly to other index data. In this way, a plurality of e-mail sending agents 41 perform e-mail sending operations for each index data. Implement load balancing to enable sending e-mail at high speed to be.

Hereinafter, the case of an individual mail will be described.

In the case of individual mails, the individual mail unit 29 determines whether index data exists in the main index queue (S51), and if index data exists, determines whether there is a space for storing index data in the sub index queue (S53). If space exists in the sub index queue, the index data of FIG. 4E stored in the main index queue are sequentially received (S55). The mail information stored in the file database 33 is read out based on the received index data (S57). That is, the mail information is read by accessing the file in which the mail information is stored based on the session ID and the folder ID of the index data. The read mail information indicates a storage path of the file database 33 including a session ID for identifying a session for sending an e-mail and a file ID of mail data stored in the file database 33. The unit 29 stores and indexes the mail information in the sub-index queue of the individual mail unit 29 as an index unit (S59). That is, unlike in the case of the broadcast mail, one piece of mail information is included in the index data stored in the sub index queue. Based on the index data stored in the sub-index queue, the e-mail sending agent 41 sends an e-mail as described below, and after the sending is completed, the queue is deleted so that the index data is continuously present in the main index queue. It is determined from time to time whether the sub index queue is empty and the process proceeds so that the index data always exists in the sub index queue, so that the e-mail sending agent 41 performs the e-mail sending operation without interruption, thereby providing high speed e-mail. You will be able to send a large amount of.

As described above, the agent manager 31 determines whether there is an e-mail sending agent in the idle state among the plurality of e-mail sending agents 41 each time the index data exists in the sub-index queue (S61). ), If there is an idle e-mail sending agent 41, the mail data stored in the file database 33 is read out based on the file storage path of the mail data extracted from the index data read from the sub-index queue. (S65) However, since the mail data file stored in the file database 33 includes the recipient e-mail address and the e-mail content in the case of individual e-mails, the e-mail address is combined with the e-mail content unlike in the case of the broadcast mail. Step S67 is not necessary. Then, by activating the idle e-mail sending agent 41 (S69), the e-mail sending agent 41 connects to the e-mail receiving server based on the recipient e-mail address stored in the sub index queue (S71). In step S73, the e-mail is transmitted.

Here, the agent manager 31 manages the plurality of e-mail sending agents 41, and whenever the index data exists in the sub-index queue, activates the e-mail sending agent 41 in the idle state for each index data to perform e-mail. Since the e-mail sending agent 41 completes an e-mail sending operation for a specific index data, as long as there is index data other than the index data currently being processed by another e-mail sending agent 41, It is possible to perform dynamic processing for sending e-mails directly to other index data. In this way, a plurality of e-mail sending agents 41 perform e-mail sending operations for each index data. Implement load balancing to send email at high speed will be.

The following describes the bulk e-mail sending process in the remote machine 2.

The remote machine 2 performs data communication with the e-mail sending server 1 to determine whether there is index data stored in the main index queue of the receiving unit 25 in the e-mail sending server 1 as described above. (S51), it is determined whether there is space for storing index data in the sub-index queues of the remote broadcast mail unit 37 and the remote individual mail unit 39 (S53), and receives the index data from the main index queue ( S55), the indexing operation according to the broadcast mail and the individual mail as described above is stored in each sub-index queue (S59).

In addition, the agent manager 31 and the e-mail sending agent 41 in the remote machine 2 are the same as the agent manager 31 and the e-mail sending agent 41 of the e-mail sending server 1 described above. Will perform the action. That is, it is determined whether there is an e-mail sending agent 41 in the idle state among the plurality of e-mail sending agents 41 each time the index data exists in the sub index queue depending on whether the individual mail or the broadcast mail is present. (S63), if there is an idle e-mail sending agent 41, the file data stored in the file database 33 is read out based on the index data read from the sub index queue (S65), The read e-mail content is combined with the recipient e-mail address (S67). The content data of the broadcast mail and the mail data of the individual mail are read out from the file database 33 by the file transfer unit 35 and received. Then, by activating the idle e-mail sending agent 41 (S69), the e-mail sending agent 41 connects to the e-mail receiving server based on the recipient e-mail address stored in the sub index queue (S71). In step S73, the e-mail is transmitted.

Here, the agent manager 31 manages the plurality of e-mail sending agents 41, and whenever the index data exists in the sub-index queue, activates the e-mail sending agent 41 in the idle state for each index data to perform e-mail. Since the e-mail sending agent 41 completes an e-mail sending operation for a specific index data, as long as there is index data other than the index data currently being processed by another e-mail sending agent 41, Dynamic processing that can perform e-mail sending operations on other index data is possible. In this way, multiple e-mail sending agents perform e-mail sending operations for each index data. Therefore, load balancing due to parallel processing is performed. To be able to send e-mail at high speed to be.

Furthermore, by creating the main index queue in the receiving section 25 and connecting the remote machine 2 to the email sending server 1, the broadcast mail section 27 and the individual mail section of the email sending server 1 ( The remote machine receives the queue stored in the main index queue so that the remote broadcasting mail unit 37 and the remote individual mail unit 39 can process the queue stored in the main index queue without the system stopping while the processing is in progress. It is possible to process and send a large amount of e-mail at high speed by dynamically processing parallel processing of the e-mail sending processing process that 1) must bear. In other words, the plurality of e-mail sending agents 41 in the e-mail sending server 1 speeds up the e-mail sending processing by dynamically parallelizing the load for the e-mail sending that one machine needs to process. The plurality of remote machines 2 connected to the sending server 1 speeds up the e-mail sending process by dynamically parallelizing the load for data processing for the e-mail sending.

In addition, the broadcasting mail unit 27, the individual mail unit 29, the remote broadcasting mail unit 37, and the remote individual mail unit 39 include information on the e-mails that are not sent and failed to be sent and received by the e-mail sending agent 41. Information about the cause of the failure to send—for example, the number of e-mails you attempted to send, the number of e-mails that sent successfully, and the list of e-mails that failed to send, and the reason for the failed e-mail address is no longer valid.
