emails

I've noticed a few friends have automatic email signatures that say "thank you, such and such". I'm not sure that's the best option. It's okay if they are really thanking them me for something but if it's just, "I think we should go with the wood ceiling rather than the drywall ceiling, we tried convincing him of that, thank you" doesnt make much sense, It's even worse when it's a boob forward, "thank you" just seems weird.
