The look and feel of your main business email address is an important choice. I say main because most people who use email a lot have more than one email address. Your main address is the one you communicate with your important clients or customers with. It’s the one everyone knows you by. It’ll often be printed on a business card and listed in other made-for-human places to be read. A strangely formatted address makes it hard to remember and increases the likelihood of typos tremendously. Take some time to plan your address well.
