Triggers with longer times

Would like the ability to create triggers for emails that are longer than 30 days after checkout.  This would be easy to do and would help immensely in re-targeting guests who have already booked without the need for a secondary CRM.  I think in theory OR isn't opposed to it, since the new zappier integration with Mail Chimp would allow the same kind of triggers.... but it seems crazy to have to purcahse Zappier and Mail Chimp subscriptions just to do this.... Would love this feature!

There's a reason we have the 30-day limit - that's generally recognized as being related to the specific business transaction (the booking) and so does not require any special permissions, opt-outs, unsubscribes, etc.  MailChimp and such already support those legal restrictions, but at present OwnerRez does not - nor do we have to because, by definition, all our automated email is within the limit.

Would love to be able to retarget my gusts in a year after they stay.  I think it would add great value.  However, there is no guarantee that the past guest would rebook.  So, I don't want to spend money on mail chimp or anything else like that.

Since they have stayed with us, aren't they automatically opting in to us emailing them again?  What if we put something in our rental agreement that says you agree to receive marketing in the future.  Would that suffice?
