Guaranteed success! Good luck not having an office complaint filed. Or loosing the client.

How professional.

...why?

Well, he's not mad. It's pretty much Guaranteed he will let you Service him in the future. May I suggest a silk and leather number for your next meeting?

Why didn't you make double check the name and address you were sending the email to?

Your lucky if you can learn from a mistake. You are doubly-lucky, you learned 2 things. 1 Always proofread. 2. He's not into you.

I call BS. You absolutely sent it to him on purpose, and made it look like you were sending it to a friend. Honestly, what are the odds that his e-mail is so similar to the one friend who you'd want to have this discussion with that it auto-completed with the other person's e-mail? I think you wanted your client to know you had a thing for him, and wanted a fail-safe in case they got offended, so you could say "OMG- I'm so sorry, I meant to send that to someone else. I wasn't actually hitting on you." In junior high, note "accidentally" end up in the wrong lockers, and people "accidentally" text their crush that they like them, when they "meant to" text someone else. Seems you didn't feel that needed to be left behind when coming to the workplace.

Oops- looks like I was not aware of all of the posting rules. I will say then that it might be a good idea to take extra care when the e-mail of the person you are sending an email to is close enough to the e-mail of the person you're sending the e-mail about, that one could auto-complete as the other.

You never know, this could be good for business!

Don't think any man wouldn't take it as a compliment, so I wouldn't worry about it.
