We're thinking about using Profile Validation, Bad Email and Missing Email messages but are confused/concerned about the frequency. From my understanding, once you set it up for a user you cannot change the frequency in perpetuity. We don't want to badger folks for their information, but we do want it. How have you handled this?
Is this a new feature? Automated? Sorry that I cannot answer your question but I am interested in the feature.
It's been around for a while and looks promising but the problem is that once you set it up for a user there doesn't seem to be a way to change it so people get the same message, at least for profile validation, at the same frequency. Right now we've decided to hold off.
