By default, each suppression list will store anyone who ever unsubscribes, hard bounces, marks your emails as spam or soft bounces over multiple campaigns. To ensure these individuals are never emailed again, any email addresses in your suppression list cannot be added to any of your subscriber lists.

Accessing the suppression list

You can access your suppression list at any time from the subscriber list index page. Once you access your suppression list, you can easily add and remove addresses you'd like to be included.

Controlling which lists use the suppression list

While all of your lists add any unsubscribes to the suppression list by default, you can turn this on or off on a list-by-list basis. If you'd like to ensure a particular subscriber list does not scrub any new subscribers against the suppression list or update it with any unsubscribes, click on any subscriber list and head into the "Unsubscribe Options" for that list (under List Options on the right).

You'll now notice a setting at the top of "Unsubscribe Options" that lets you set how any unsubscribes are handled. If you would like to ensure this list never uses the suppression list, select "Only unsubscribe from this list". If you'd like any unsubscribes to be added to the suppression list, which we recommend, select "Unsubscribe them from all this client's lists".

You can change this setting at any time. If you decide to change your subscriber list so that it hooks into the suppression list, you'll be given the option to make updates to both lists. These options allow you to instantly add anyone who previously unsubscribed from that list to the suppression list. You'll also have the option to scrub all of your active subscribers in that list against the suppression list.
