[0040] An embodiment of the present application provides an email processing method, which matches the emails to be processed by using a preset label library, thereby obtaining target emails that meet certain conditions, and uses a matching first processing flow to process the target emails, thereby making the email processing process more targeted and improving the email processing efficiency.

[0041] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application are clearly and completely described below. Obviously, the described embodiments are only embodiments of a part of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should belong to the scope of protection of the present application. At the same time, for the sake of clarity and simplicity, the description of well-known functions and structures is omitted in the following description.

[0042] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0043] With the development of science and technology, people's communication methods have changed greatly. At present, email communication is a common communication method used by people in work and life. Email is a communication method that provides information exchange by electronic means and is the most widely used service on the Internet. Through the email system of the network, users can contact network users in any corner of the world at a very low price and in a very fast way. For enterprises, there are many business parties that are in contact with each other, so the number of emails is also large. The processing method of emails is generally that customers send them to the company's summary mailbox, and then each email is assigned to the customer service colleagues for email tracking and processing. This processing process has a certain lag in the processing of some important emails, which is easy to cause certain problems.

[0044] To solve the above problems, the present application provides an email processing method. Figure 1 , an embodiment of the mail processing method provided in the present application includes: step 101-step 103.

[0045] 101. Get pending emails.

[0046] Specifically, pending emails are obtained, and pending emails are obtained from the target email address. Pending emails are emails that need to be processed. Pending emails are emails sent by customers to enterprises. The target email address can generally be a specific email address, wherein the target email address can be a certain email address or multiple email addresses, which can be determined according to the actual situation and is not limited here. In the actual implementation process, this step can be completed through the Enterprise Resource Planning (ERP) system, that is, the ERP system automatically pulls emails from a specific email address to the ERP email server at a fixed time to support the implementation of subsequent steps. It can be determined according to the actual situation and is not limited here.

[0047] 102. Match tags between the preset tag library and the email to be processed to obtain the target emails with successful matches.

[0048] Specifically, match tags between the preset tag library and the email to be processed to obtain the target emails with successful matches. The preset tag library is pre-set by the staff and includes multiple tags. The tags are used to reflect the status of the email to a certain extent. For example, in the scenario of using this method to process urgent emails as soon as possible. The tag content can be tags corresponding to the urgency level, such as in the form of "@General Manager" or "@Specific Manager". At this time, match all the data in the email to be processed with the preset tag library. If the match is successful, that is, there is content in the email to be processed that is the same as the tags in the preset tag library, then determine the email with a successful match as the target email for further processing. It can be understood that the data used in the matching process not only includes the content of the email, but also can include information such as the sender and recipient, which can be determined according to the actual situation and are not limited here. In addition, the tags in the preset tag library can be set differently based on different purposes. For example, in the case where this method is applied to the customer service evaluation process, tags such as "Good Review" and "Excellent" can be set. Then, the target emails representing good reviews can be screened out through this step, which can be determined according to the actual situation and are not limited here.

[0049] 103. Process the target emails based on the first processing flow.

[0050] Specifically, process the target emails based on the first processing flow, where the first processing flow is determined according to the tags in the preset tag library and is not limited here. For example, in the case where all the tags in the preset tag library are tags reflecting urgent processing, the first processing flow can be an urgent processing flow, that is, the first processing flow triggered at this time is to give priority to processing the target emails, and other emails that do not match successfully will be processed after the processing of the target emails starts. Or in the case of being applied to the customer service evaluation process, the good and bad review information for the customer service system can be recorded accordingly according to the content of the matched tags, which is not limited here.

[0051] From the above technical solutions, it can be seen that the embodiments of this application have the following advantages: This application provides an email processing method, including: obtaining the email to be processed; matching the preset tag library with the email to be processed to obtain the target emails with successful matches; processing the target emails based on the first processing flow. Based on this method, it can be known that this method matches the email to be processed with the preset tag library, and then obtains the target emails that meet certain conditions, and uses the matching first processing flow to process the target emails, so that the email processing process is more targeted. Applying this method to the ERP system improves the processing efficiency of emails in the ERP system and improves the usability of the ERP system.

[0052] To facilitate the use of this method in the actual mail processing process, this application also provides a more detailed embodiment that can be optionally implemented, please refer to Figure 2 , an embodiment of the mail processing method provided in the present application includes: steps 201 to 207.

[0053] 201. Get pending emails.

[0054] Specifically, the method can be completed based on the ERP system to obtain pending emails. The pending emails can come from one or more email addresses, which are not limited here. The ERP system collects pending emails and stores them on the ERP email server for subsequent steps. The judgment rules for pending emails can be determined according to actual conditions, such as determining that all unread emails are pending emails, or determining that emails received within a specific time period are pending emails. The specific rules can be determined according to actual conditions and are not limited here.

[0055] 202. Matching is performed with the to-be-processed emails based on the preset tag library to obtain successfully matched target emails.

[0056] Specifically, matching with the pending email based on the preset label library includes: judging whether there is content consistent with the label in the preset label library in the pending email, if there is content consistent with the label in the preset label library in the pending email, it is determined that the pending email matches the label of the preset label library successfully, if there is no content consistent with the label in the preset label library in the pending email, it is determined that the pending email matches the label of the preset label library unsuccessfully. The preset label library is pre-set to indicate the importance and urgency of the email, such as the name labels of some important customers or the name labels of the heads of business departments in the preset label library. When the email matches the label in the label library successfully, it means that the email has a higher priority for processing, and the email is determined to be the target email, and step 204 is executed to add a first-level response label to the target email. For emails that are not successfully matched, it means that there is no priority processing requirement, and they can be handled according to the general process, that is, step 203 is executed to process standard emails based on the second processing process.

[0057] 203. Process the standard email based on the second processing flow.

[0058] Specifically, standard emails are processed based on the second processing flow, and other emails that are not successfully matched in the emails to be processed can be processed according to the second processing flow, wherein the second processing flow can be a general processing flow, that is, the corresponding customer service personnel are assigned, and the customer service personnel contact the corresponding responsible personnel to complete the processing. It is worth noting that in the process of customer service personnel processing standard emails, there may be some emails that have a higher actual processing priority, but are not successfully identified based on the preset label library. At this time, the customer service personnel can add a first-level response label to such emails and process them as described in steps 204 to 206.

[0059] 204. Generate a first work order based on the target email.

[0060] For the target email that successfully matches the preset label library with the email to be processed, a first work order is generated based on the target email. The system extracts the relevant information of the target email with the first-level response label, and generates a first work order based on the information, wherein the main categories of relevant information include: email title, product-related information, first-level response label, and the name and ID information of the person in charge at each level, etc. The first work order is used to record the processing status of the target email. It is understandable that in order to facilitate tracking of the processing process of the target email, a first-level response label can also be added to the target email, wherein the first-level response label is used to indicate that the target email needs to be processed first, and the form of the first-level response label can be determined according to the actual situation, which is not limited here.

[0061] 205. Obtain the processing result of the first work order.

[0062] Specifically, the processing result of the first work order is obtained. After the first work order is generated, the responsible customer service personnel will communicate with the business personnel to communicate the relevant issues reflected in the email, and draw a processing conclusion, and record the corresponding processing result in the first work order.

[0063] 206. Store the first work order and the processing result of the first work order.

[0064] Specifically, the first work order and the processing result of the first work order are stored. After the first work order is generated, the first work order can be stored in the first-level response form to facilitate data tracking and query. After the first work order is generated, the responsible customer service personnel will connect with the business personnel to obtain the processing results in a timely manner. After obtaining the processing results, the response status recorded in the first work order can be modified to feedback, so as to ensure the clarity of the processing process and upload it to the server.

[0065] 207. Feedback the processing result of the first work order to the sender of the target email.

[0066] Specifically, the customer service staff feeds back the processing result of the first work order to the sender of the target email, thereby completing the entire processing flow.

[0067] It can be seen from the above technical solutions that the embodiments of the present application have the following advantages: The present application provides an email processing method, including: obtaining an email to be processed, the email to be processed is obtained by a target email address; matching the tags with the email to be processed based on a preset tag library to obtain a successfully matched target email; and processing the target email based on a first processing flow. Based on this method, it can be seen that this method matches the email to be processed by using a preset tag library, and then obtains a target email that meets certain conditions, and uses a matching first processing flow to process the target email, thereby making the email processing process more targeted. This method is applied to the ERP system, which improves the email processing efficiency in the ERP system and improves the availability of the ERP system.

[0068] The above content describes the implementation method of the method in the case of preferential processing of emails. The following describes the implementation method of the method provided by this application in the case of applying the method to the positive review record or the negative review record. Figure 3 The implementation process of the method provided in this application for applying the positive review record or the negative review record includes: step 301 to step 305.

[0069] 301. Get pending emails.

[0070] Specifically, the implementation method of this step is the same as the above Figure 1 The corresponding step 101 in the embodiment is similar and will not be described in detail here.

[0071] 302. Search for multiple positive review tags in the content of the email to be processed.

[0072] Specifically, multiple positive reviews tags are searched in the content of the email to be processed. The positive reviews tag library includes positive reviews tags, such as "excellent" and "satisfied" tags, which can be used to indicate that the email is a positive review email. If any positive review tag exists in the content of the email to be processed, the email is identified as a positive review email, and step 303 is executed to determine that the email to be processed is a positive review email, and a positive review record is added to the positive review email. It is understandable that the tags in the positive reviews tag library can be determined according to actual conditions and are not limited here.

[0073] 303. Determine that the email to be processed is a positive email, and add a positive record to the positive email.

[0074] Specifically, if there is any positive comment tag in the content of the to-be-processed email, the to-be-processed email is determined to be a positive comment email, and a positive comment record is added to the positive comment email. A positive comment record is added based on the positive comment email. A positive comment record can be added correspondingly for each positive comment email, thereby obtaining the number of positive comment records.

[0075] 304. Search for multiple negative review tags in the content of the email to be processed.

[0076] Specifically, the multiple negative review labels are searched in the content of the email to be processed. The negative review label library includes multiple negative review labels, such as labels with words such as "unsatisfied" and "disappointed", which can be used to indicate that the email is a negative review email. If any negative review label exists in the content of the email to be processed, the email is determined to be a negative review email, and step 305 is executed to determine that the email to be processed is a negative review email, and a negative review record is added to the negative review email. It can be understood that the labels in the negative review label library can be determined according to actual conditions, and are not limited here. It can be understood that there is no logical relationship in terms of time sequence between this step and step 303, and the execution order of the two can be determined according to actual conditions, and are not limited here.

[0077] It is worth noting that the content of the pending email may contain neither a negative review tag nor a positive review tag. This means that the pending email is not an email used to evaluate the customer service department and can be processed in other conventional ways, which are not limited here.

[0078] 305. Determine that the email to be processed is a negative review email, and add a negative review record to the negative review email.

[0079] Specifically, if any negative review tag exists in the content of the to-be-processed email, the to-be-processed email is determined to be a negative review email, and a negative review record is added to the negative review email. A negative review record is added based on the negative review email. A negative review record can be added correspondingly for each negative review email, thereby obtaining the number of negative review records.

[0080] The good and bad review records of the customer service department obtained based on the matching results of the positive review tag library and the negative review tag library can more objectively reflect the service quality of the ERP customer service department. The above method provides data support for the performance evaluation of the ERP customer service system.
