As someone who's been through this many times, here's a tip:
Any time someone emails you about acquiring you, hiring you, sponsoring you, etc, just assume the actual odds of it happening are about 1%, and be happily surprised if something eventually comes of it.
If they really, really want you, they'll be hitting you up every chance they get.
I think this is true but there's also a whole range of people who are on the fence and can be influenced, and to ignore them is a suboptimal and (imo) losing strategy.
