Hi everybody!

I happened to see some people writing "kind regards" at the end of a commercial letter or e-mail. Is that a correct option instead of "best regards"?
does it exists? I've never seen it in books..

Thank you in advance!

"Kind regards" is ok. Some people simply write "regards" or even "rgds" (this one must be quite informal).

kind regards = little more familiar then best regards
kind regards/ best wishes are ok
all are ok for email

Kind regards for cordiali saluti (more friendly, you should know the person you're talking to)
Best regards for distinti saluti (more formal)
