I would like to inquire about the usage of word "kindly" to close an email instead of "best", "sincerely" or ....etc.
Can the word "kindly" be used to close an email, for example:
I would like to thank you for the great help yesterday!
I see it very strange, but many people in my institution are using it to close their emails! Kindly, is this usage of "kindly" is correct?
