This could be due to several reasons:

SPAM FILTER

Most often, this is due to an aggressive spam filter - either on your email client, or through your ISP.  Please check that emails from xanga.com are on your email whitelist!

HACKED!

If someone has signed onto your account and changed your email, then it's possible that your emails are being diverted to the new email on file.  If you suspect this is the case, please see:

Someone has hacked my account and changed my password!

WRONG EMAIL

Is it possible that you used another email address to register your Xanga site?  Please check some of your other email addresses, to see if any of those are the one you used to register your Xanga account.

TYPOS

Is it possible the email on file is not correct?  Sometimes a typo in the email address will prevent emails from getting through.  The best way to check this is to see if you have any emails from Xanga related to this account (for example: Subscription Digests, Feedback Logs, or Welcome to Xanga emails).

If none of these is the issue, then please either try requesting your password again:

I forgot my password?! Please email it to my email address on file!
