A Suppression List is a list of suppressed e-mail addresses used by e-mail senders to comply with the CAN-SPAM Act of 2003. CAN-SPAM requires that senders of commercial emails provide a functioning opt-out mechanism by which email recipients can unsubscribe their email address from future email messages.

The unsubscribed email addresses are placed into a “suppression list” which is used to “suppress” future email messages to that email address.

There are two types of suppression lists within Oempro

  • Local Suppression List
    This the list specific suppression list only valid for the particular mailing list.
  • Global Suppression List
    The subscribers added to global suppression list will be excluded from mail deliveries from all the mailing list under the users account

The local suppression list can be used to suppress the email addresses from a particular list.

The suppression lists are created whenever the hard bounced email addresses are detected or when you manually add certain subscribers to the suppression list.

  6. Click on the “Next” button to import subscribers to local suppression list.
