Adds one or more domains to the suppression list. Once added, any email addresses belonging to these domains will be blocked from receiving further communications from your account. This is typically used to suppress domains that bounce frequently, are spam traps, or belong to users who have requested to never receive emails from your brand.
For example, Suppressing example.com will block emails to [email protected].
The system automatically removes the www. prefix if present.
