Bring on any domain you own to Port87. You retain your @port87.com address, and can add any domain you own to your Port87 account. If your subscription
includes additional users, you can create new Port87 user accounts with addresses
on your domains for other people.
You can set up your domains as personal domains (label@example.com) or multi-user domains (username-label@example.com).
If you don't yet own your own domain name, you can follow Cloudflare's helpful guide to get started.
Using Port87 for your email will not impact any web hosting you already
have on your domain. Email and web services run separately, so you can
have different providers for each.
