Typically, if you sign up for an email account, you get an email address like skywal@gmail.com or skywal@yahoo.com. Alternatively, if you own/host skywal.com, you can have an email address like skywal@skywal.com served from a computer in your home.
The "sweet spot" is combining the two, where you own skywal.com, and have your email send/receive through Google or whoever. Then, if Google decides to ban you, you just register skywal.com with another company who provides that same service, and you keep your same email address.

That's the broad strokes anyway.
