We introduced a new set of membership types and are naturally phasing out the old types (they will expire, on a rolling basis, but can not be renewed). We want to send people of the old types a scheduled reminder with a notice to renew at the new levels (X days before expiry), but only if they have not already renewed at the new levels. I thought I could do a Search Builder to make a smart group of all contacts who were "not in" the current levels and restrict it to that, but it is encountering some silly logic error and continued to send them reminders. How would you approach this?
Recap. Send renewal reminders to old membership types, but only if they have not renewed.
Thank you. Latest Civi and D7.
Worst case, I can add text to reminder that says "If you have already renewed, please ignore" but that is annoying.
