Recently Google announced that Gmail has more than over 1.6 billion active users, so there is a good chance that the username you want is already taken by others.
As a result, it’s very difficult to come with a unique email address especially when you plan to use it in the long run.
Nobody wants an email address that looks like [email protected]

But don’t despair entirely. What you need is a username that is unique enough to perfectly represents you and your business.
