That's bad. Can you recall the email? Although nothing wrong, just a typo. I think you will be fine.
I had worse, I once was typing a url address in the browser at work and accidentally typed the address of this board (the names were close enough in the first part of it and my finger memory played a mean trick on me). Obviously, the address got a blocked result. No consequences for me, and I cleared the cache etc, but I know that all hits and requests are monitored and stored. This was a while ago, so I think I was given a slack back then.
