Our communications staff wants to be able to resend a mailing (or send a new mailing) to recipients who did not open a previous mailing. Of course, this is possible by creating a group from the "unique opens" of the first mailing, and then excluding that group in the new mailing.
Unfortunately, there are a number of steps with this, and it seems like a sufficiently useful workflow that I'd be interested in it as a new core feature. Other mass mailing services like Constant Contact have a "resend to non-openers" feature.
Before I open an feature request issue in lab.civicrm.org, I wanted to test it here to see if others feel it might be a worthwhile feature, or if there is some other way to streamline the workflow.
