Hi @kuliff, 

There are two steps you’ll want to take to remove unwanted email addresses:

1. Build a segment of the email addresses you don’t wish to include in your regular sends. Simply use the condition “Properties about someone” > Email> contains> @amazon.com. This definition will grab anyone with that domain in their email address Here is an example of that segment definition:

   

    

2. Once you have the segement built, you can remove these emails permanently from your account by navigating to Account > Settings > Account Maintenance. Here, you will see a Remove Profiles section where you can choose a list/segment from a dropdown menu. Choice the segment you just build and select delete. Its important to note that if you delete people via the Account Maintenance tab, these profiles will be completely erased and no history will be kept -- this is permanent. Be absolutely certain you would like to delete these profiles, because this can action not be reverted.

Our guide on List Cleaning provides additional instructions and tips on how to clean out unwanted email addresses! 

Best,

Melissa

Thank you!
