What are different ways to sign off a formal e-mail?

Question

The only ones I can think of are "Thank you" and "Sincerely."

Answer 1

I use "Sincerely."

You can also make a professional signature that automatically stamps your name, work address, work phone number, and work e-mail at the bottom of the letter.

Answer 2

First of all, email is not "formal".

But an alternative would be:

With kindest regards,

Or just:

Regards,

Hope that helps!
