Request Handling by ESPs: All requests related to complaints handling are managed exclusively by the ESP. There is no direct way for the client to influence the process of receiving complaints at a specific email inbox. The ESP entirely determines the process. Here's a look at how it works:
-
Feedback Notifications via Webhooks: While you, as a client, cannot directly change the "complaint domain" (since it's tied to the domain used for sending emails), you can work with your ESP to set up webhooks. These webhooks notify you of spam complaints, allowing you to receive real-time updates. Instead of changing the complaint domain, you can configure a custom URL where your application or server can receive the feedback.
-
Suppression List Management: Once registered, all complaints automatically add the email to the suppression list within the ESP's dashboard. This helps the ESP manage and track complaints based on the sending domain. Although you cannot change the sending domain's complaint setup, the ESP provides these tools for monitoring and responding to complaints.
Summary:
- The complaint domain is tied to the domain used to send your emails.
- While direct changes are not possible, if you need to remove the user from the block list or double-check that your webhook is configured correctly, please contact our support team.
