Suppression List

Important: Administrative permission is required to access the Zift123 Settings. For more information, contact your supplier point of contact.


The suppression list is a list that contains email addresses that are permanently excluded from your email lists and will not receive future emails. The list is comprised of contacts that have opted out/unsubscribed from the Zift123 user’s email marketing. All contacts deactivated by the Zift123 user will also fall to the suppression list. These email addresses can not be accidentally emailed to again by any user in the Zift123 account.

As a convenience, we automatically quarantine undeliverable email (hard bounces) and unsubscribes in your suppression list. However, Zift123 is unaware of any email addresses that you have bounced in other email marketing platforms. Import your suppression lists from these marketing platforms into Zift123 to protect your sender reputation and optimize your email efforts. If you have experienced a high bounce rate in other email marketing tools and do not take this critical step in protecting against unknown suppression, you may be penalized, up to and including permanent suspension.
