AliExpress platform provides an automatic reply function, which can automatically reply to the corresponding information based on the questions sent by the buyer. Here are the steps to set it up:

1. Log in to your AliExpress account and find "Customer Service-Message Center" in the navigation bar.

2. Click "New Message Template".

3. Select "Automatically reply by rules" and fill in the message content and corresponding rules for the reply.

4. Click "Save" to complete the automatic reply setting.

It should be noted that when setting up automatic replies, the relevant regulations of the AliExpress platform should be followed, such as not violating platform rules, involving sensitive information, etc. At the same time, automatic replies cannot completely replace the role of manual customer service, and manual intervention is still required for some more complex issues.
