We are looking at our recipient activity reports and seeing that there are several email addresses that show as unrecognizable character strings. A couple of these addresses show a lot of email open and click activity and we would like to have some idea of who they are and what is going on. Your help is much appreciated.
If you insert the full tracking links into the message (do not hide them behind an anchor text), in some email clients tracking links may be broken in two lines. In most cases this happens if the recipient opens your message in the plain text format. In this case the last part of the link where the encoded recipient's email address appears on the second line. But the link is working. When a recipient clicks on it, the page opens well but the recipient's email address may not be registered correctly.
