Someone thinks you're not very good at email.
They've sent you this link for one of the following reasons:

- They simply cannot be bothered with dealing with stupid people who refuse to learn how to communicate.
It's the 21st century. Email has been around for a little while now. It's a mandatory communication tool. It's a life skill, just like Googling. You need to know how to use email. You're functionally illiterate if you can't.
Your offence was:

Okay, so this one's the double-whammy. Not only did you fail the "I can use email" test but the "I can use Google" one as well.
