I've been thinking about moving to FastMail for quite some time now for pretty much the same reasons you mentioned.

What still keeps from switching though is that I rely on services like SaneBox and Unroll.me for organising my email. Unfortunately, the last time I looked only GMail is properly supported by these services and there doesn't seem to be a vendor-independent alternative either.

Does anyone here use services like SaneBox with FastMail?
