Lists are somewhat more constrained than Data Extensions, but unfortunately, Suppression Lists (as opposed to excluding via DE) are the only way to suppress/exclude subscribers from Journeys.

This means we need to programmatically/automatedly 'overwrite' (or delete and rewrite) a suppression list. Has anyone successfully manage to do that?


You should review the concept of Auto Suppression Lists. https://help.marketingcloud.com/en/documentation/exacttarget/admin/auto_suppression_lists/

Auto-Suppression Lists can be assigned to specific Send Classifications and therefore give you more flexibility. You can import directly into a Auto-Suppression List via an Import Definition which allows you to add or overwrite the Auto-Suppression List.

In case you shouldn't see Auto-Suppression List under e-Mail >>> Admin you can simply reach out to support asking for it to be enabled.

  • Thanks - I had ignored these as I had incorrectly assumed they behaved like other lists (and therefore don't allow overwrites), but digging into the documentation, it looks like they behave like Data Extensions, and therefore can be overwritten! Nov 23 '16 at 17:16
