Mailpile is great. I use it as sort of a webmail for my private email server. But it's not even close to Gmail, and has no calendar, or note taking app (yes, I actually do use Keep). I don't think FastMail can really compete with G Suite on anything except "not being the leviathan." Which is not nothing! But as a tool, it's just not as good. And Outlook which you mention in the comment below doesn't even have this. Let's not underestimate Google here. They offer a full productivity suite, an excellent, tight integration with Android, plus Chrome sync for multiple profiles. They're tough competition.
