I'm a fan of moving away from Google where possible as well, but Fastmail would cost me $500/year with 10 accounts. My G Suite account is one of the original, so I can have up to 200 accounts for free. Granted, it's only 15GB of storage, but even after about 10 years, I only have about 1GB in my inbox, so I'm ok with the lower amount of space.

Wow, what do you do with 10 accounts? Isn't checking all of them a hassle?

I have multiple domains and aliases, and Fastmail is much better at those than Google Apps ever was (I also have the free plan but you can never change your initial domain), so I'm much happier.

Several accounts are for separating services - AWS has it's own account, for example, so does Dropbox. I use a different email address for forums and such.

A few for friends and family as well. --Friends I can tell to pay for themselves if I need to, but family, not so much.

Edit: As for checking them, most don't get many emails, and every good email app can handle multiple accounts easily, so I get notifications on my phone.

Fastmail allows you to do things like [e-mail], and then you can filter emails by that domain name. Lets you easily block out spam without having completely different email addresses.

I have six. Some of my clients ask me to manage their AdWords for them. Plus, I occasionally need to log in to my wife's Gmail account. (To confirm logins when paying bills, for example. Anything personal, she's smart enough to keep on her own domain.)

[StavrosK]

So you don't really have six, you just have five of other people's logins?

Fastmail give you free aliases.

FastMail aliases are great. I've used some for sites I'm more likely to want to cut off access to me, for instance. Whereas [e-mail] gives you sortability, a true alias gives you the easy ability to just shut a site out of access to you.

Another issue I had was that my main email address was already in Google and Microsoft's systems for a couple reasons, and it wouldn't let me set it properly when changing my email address everywhere. So I have google@ and microsoft@ aliases just to work around their account management quirks.

The problem with aliases is still that they route to one account, and if it's compromised, there's no separation.
