Choose your email address wisely. When you send out that resume, do you really want to use TonsOfFun57@Yahoo.com or something similar?

If you have a website, consider using that for your email address. That would give you BetterName@MyWebsite.com.

Case does not matter in email addresses and is only used to clarify the address. So when you choose an email name that looks good in mixed case, be sure that when it is seen in all lowercase, it does not say something you did not intend (e.g. ChooseSpain becomes Chooses Pain).
