Lifehacker: Email Annoyances

Lifehacker put up a post yesterday dealing with the worst email annoyances. I’ve dealt with my personal worst email annoyances on this blog over the years. My two biggest are Reply to All and “You’ll win something if you forward this to everybody”.

I’m not really annoyed with signature lines like “sent from my iPhone” or “sent from my Verizon BlackBerry”. It tells me the person is probably out of the office. Hopefully I can expect more information when they get back to the office, but I usually have to follow up again.

What do you consider an email annoyance?
