I've got a email message from your site but there is a garbadge inside it.

Usually it's a problem of non ASCII users like Russians, Chinise, Japan, Korean, Arabic etc. The problem can be in encoding that was detected incorrectly by your mail client. Our site using UTF-8 (Unicode) encoding in all pages and mail messages. You should switch encoding in your mail client to UTF-8 to be able to read the message.

To learn how to change encoding, read manual to your mail software.
