People will suggest running your own mail server, and if you have the time and energy then definitely do that.
But the next best thing you can do is simply just use your own domain. That way, you can at least decide to migrate your email elsewhere. Don't use the free domains you get from things like gmail or other providers, because then you have to _change_ your email address, and not just your MX records.
