Some members receive our mail blasts but cannot find them as they automatically go to their spam folder. Using tools like mail-tester.com we are improving what we can in order to reduce the probability of spam classification.

One change that comes recommended is to have a List-Unsubscribe header included in the mail. This is not something we can add, so we're wondering if Wild Apricot could add this header to all mail that already have the {Unsubscribe_Url} macro.
