How to bind a domain name for mass mailing?

EDM mass sending usually uses the public chain for mass sending, and the public chain may be restricted by the receiving party due to too many sending times. In this way, you can try to bind the customer's own second-level domain name address as the sending chain to reduce the chance of sharing restrictions. The following takes Alibaba Cloud as an example

1. Enter Alibaba Cloud background, find Cloud DNS DNS in the sidebar and click to enter

2. After entering, click the domain name to enter the settings

3. Click Add Record to add a second-level domain name. Fill in "maill" or other domain names you need to display in the host record, and fill in "10.10.10.10" in the record value and click OK. Then, for example, mail+domain name is provided to customer service. Such as: mail.xxxxx.com

4. After the domain name is provided, the parsing file will be obtained, and the three columns of field type, host record and configured record value will be used in the file

5. Fill in the contents of the file correspondingly as shown in the figure below, and you need to fill in the analysis information line by line.
