We have 20 or so domains we do not want to ever send emails to. They are mostly competitors.
It would be nice if we could edit a suppression list ourselves without having to request through your support.
We currently offer this feature. Contact support to request this be enabled for your account if it is not currently in the menu option under Contacts => Manage Suppressions.
Note: This feature is limited to 3000 entries maximum.
One domain or one email address counts as 1 entry.
Would like to have this feature without contacting support every time I want to add to it.
