Whatever you do, keep it short and easy to spell and type. I solicit and have to enter email addresses all the time, and we get a high error rate between the owner writing it down sloppily and/or the data entry person making an error. Too often I see something really clever that is hard to say, spell, and type and is bound to be entered incorrectly, meaning no email. Forget your first name plus your last name unless they are very generic and unlikely to be misspelled or mistyped. The absolute best email addresses are just your first name, if it is easy to spell and type, with a short domain name that is easy to spell and type. If it were available, something like
sally@gmail.com would be perfect. Try to get your own domain, and make it short and really, really easy to spell and type. That's why you see lots of tech companies with short names that mean almost nothing, but sound catchy and are easy to spell and type. Think Gmail, Amazon, Twitter, etc.
