How can I delete a former e-mail address?

Quaro: I did email blast before, now I want to delete unsubscribe ones to clean the list. But I got a headache trouble, some guys replied using a total different email address, I can't specify it's original one in my list. How should I do?

• is there any way to track the original email address when I get a reply whatever the email address he used?

• Answer:

  You might be able to see it by analyzing the detailed email header of the message you originally sent, which could still be part of the customer's reply. See: http://www.mxtoolbox.com/emailheaders.aspx That said, the scenario that you are encountering is one of the reasons why the unsubscribe process should never be handled that way, but rather with an unsubscribe link that directly updates your recipients database. Make sure to follow email marketing best practices next time. Any professional email marketing system allows you to include a properly configured unsubscribe link in your messages.
