Email is good.

You can always change your email address. Just make a new one and forward the old one to the new one (for a while).

But when you’re using a service for email, you’re at their whim on what they allow. Gmail will certainly allow you to make a new one and foward the old one to the new one, but wouldn’t it be nice if it wasn’t an entirely new account so you could retain archived emails? Just pointing out that as of last Christmas, you can change your Gmail address now, and retain everything.

I haven’t looked into if you can go to an @gmail.com address to a custom email address yet, but that’s the one I’d be tempted by. I’ve been using my chris@coyier.com email through Fastmail, and I like it, but I haven’t had the guts to entirely forward chriscoyier@gmail.com to it, which I’ve used for like 20 years. If I could just change my email to that, it would be a lot more tempting.
