Which valediction should I use with my boss?
Solution 1:
There are numerous sign-off phrases used in letters, but most e-mails are more succinct, often forgoing closing phrases and even omitting a name at the end (because it presumably appears in the To box). This is especially true if there is a standard signature block containing business card-like information at the end of the message, often automatically generated.
If you feel a closing phrase is necessary, there are many possibilities including
- Thanks
- Thank you
- Sincerely
- Sincerely yours
- Best
- Yours
- Yours truly
Many of these are fairly formal for e-mail.
Why not consider responding just as your boss does and say cheers?
[All of the above reflects a US point of view and may not be applicable in other countries. I tend to be more formal when corresponding with colleagues overseas.]
