Could somebody provide a long list of concluding greetings such as "sincerely", "respectfully", "best wishes", "faithfully", and etc for writing emails? I would like to pick one for appropriate audience. What if I know a person, which greeting should I use? Again, I would like to see the list.

The list is pretty endless. It would narrow it down if you could specify the type of email you want to write. To a customer, to your lover, to your boss, to your uncle . . .?

Consider also that many people don't put any concluding phrase at the end of an email at all. I wouldn't say that it is always expected.

And consider this Forum, where most people don't write anything like. . . Best wishes, Clive
The main distinction with formal emails is this:

If you know the person's name, you use this format in your salutations:

Dear Mr Smith,


Yours sincerely,

[Your name]

If you do not know the person's name, use this format:

Dear Sir/Madam,


Yours faithfully,

[Your name]

This is a standard for all formal letters in the UK/USA. I hope this helps.

Hi guys,

I would argue that email is by nature a relatively informal medium. I know that some people would disagree with me, but the idea of a truly formal email sounds odd to me.

If I were the owner of a small company, and I wanted to write to the president of IBM to try to get some business, I'd buy the best quality paper I could afford, get a really impressive letter head, sign in ink, and send it by regular mail.

As I said, some people may disagree.

Best wishes, Clive
Thank you for all replies. I specifically look for some concluding greetings, so that I can write a letter to a professor whom I know. I know that I will no longer use concluding greetings, once I become a friend or get into a personal relationship. There is no need for formal greetings because the professor know me.
