Why can't I attach my static list to my mailing?

It is not possible to combine a static list with a permissions-based unsubscribe package. This is due to the fact that a static list does not keep up-to-date permissions. Suppose someone were to unsubscribe based on a permission, this is not updated in a static list. The unsubscribe is then not processed. For this reason, do not use a static list in conjunction with permissions.

Use a dynamic list or change the unsubscribe package.
