First of all, buy your own domain from Gandi.net, hover, namecheap, or wherever you prefer. Then get an email account at a private provider who let's you use your own domain: fastmail, gandi, proton, tutanota.. As long as you keep paying for your domain registration, you are not beholden to a mail provider.
