Oh, another awesome thing about email is that you can ensure that your address is always yours, even if you use an email service provider like Gmail. Any provider that supports custom domains will allow you to use your own domain for your address, then if you want to change your provider, you keep your address. So, since I own hperrin.com, I can use the address me@hperrin.com, and I know it’ll always be mine as long as I pay for that domain.

This is a much better model than anything else. Even on the fediverse, you can’t have your own address unless you run your own instance.

If your email service provider goes out of business or gets sold off (skiff.com, anyone?), as long as you’re on your own custom domain, your address is still yours.

I’m working on custom domains for Port87. It’s definitely a feature I think every email provider should offer.
