My personal email address scores 1, my co-op email address (because it ends in .coop) gets a 2.

You're at the doctors office, talking to an aquaintence, or ordering something on the phone and they ask the question: What's your email? Depending on your name, age, and your life choices this can be a breeze or the dreaded question. How long does it take before you have to break out the phonetic alphabet? How many times do you have to repeat it?

Today we’re going to come up with a scoring system to measure how painful your email is to tell someone. It’s a golf scoring system with low scores being easy and each point is one unit of struggle for both you and the recipient.
