Stop mailing people who opted out or bounced.

Unsubscribes, bounces, complaints and offer lists apply to every send automatically, whichever provider it goes through.

Suppress addresses, domains and hashed lists

Block single addresses, whole domains, or the encoded lists that offer networks send.

Keep separate lists for every brand

Global lists, per-brand unsubscribe lists and an account bounce list, all unlimited.

Refresh offer lists automatically

Lists from Optizmo, UnsubCentral, CAKE, Everflow and EmailMonitor refresh on their own every 1 to 14 days.

See how many contacts each list removes

Every segment shows how many contacts each suppression list removes.

In the app

Manage every suppression list in one place

Offer lists, unsubscribes, bounces and complainers, each with its format and size. Automated lists refresh on their own.
