Like lurker, I appreciate thank-you emails. I rarely get them.
I seriously dislike super-long signatures to an email. Contact information is fine, but when you have all sorts of ASCII promo shit in your signature, or even worse, some ridiculous quotes, I find it hard to take the person seriously.
Oh, oh, even better? People who use monotype corsiva for their "signature." They're almost ALWAYS administrative women, who also include fucking flowers or some shit in their sign-off. Annoying as shit. I love contact info in the signature, though. Holy cow, has it saved my ass before.
I can't say I've ever seen anyone put a whole paragraph into a subject line or anything. That would drive me fucking
nuts though.
Jam it back in, in the dark.
