It would be awesome to have content suggestions for Subject Lines (and maybe Preview Text too) when sending marketing emails. I'd love to have something like a list of better converting Subject Lines to choose from, or even just one suggestion.

Thank you so much for the Subject Line suggestion, I think it is a brilliant idea! I'm happy to report that we're actively developing an AI Subject Line Generator for Marketing Email. We'd love to get your input on some of our initial designs/thoughts (and of course for testers as soon as we have a working demo).
