I am from the UK and work with a lot of Americans. I often sign off emails with "Cheers," which gets a lot of positive comment.

As well as being what you might say when clinking glasses, in the UK "cheers" is a jovial way of saying "thanks" as well as something you might say for "goodbye" so works in all these contexts simultaneously.

I've been doing Cheers for a long time too. Nice to see it towards the top. I prefer a more casual friendly tone and I'm pretty sure I started using it after seeing someone from the UK sign off all emails like that.

So cheers!

Yep, Brit here in the US too, and 'Cheers' is my sign-off-of-choice. I'm told that I only get away with it because I'm British though, and my American colleagues would feel awkward using it :)

Cheers!

I have a similarly positive experience with "Cheers". I always like it when someone uses it, and I often use it myself. Works really well with people you already established a connection with.
