I was wondering who was removing my "Daniel"s...
Fine. I'll try. I can't promise one won't slip in sometimes. As I've said in another comment on this exciting topic, I've been signing my posts "Daniel" for over ten years now, so there's bound to be times when I forget not to sign when commenting here. But I'll try my best.
If you sign your email "Thanks, Brian" or "Regards, Brian" or "Cheers, Brian" then that is much better than "- Brian" or nothing at all. Similarly, I include "Dear XXX," or "Hi XXXX, " or at least "XXXX," at the beginning of the message.
