I wanted to make a post here about the issue that the mailer had this morning. Between midnight and 9am eastern time, the mail was sending out e-mails without the paid links. The default has always been and currently is to never send out any e-mails without a paid link inside. I ran the auto update utility and sent out a test e-mail, which showed correctly with the paid link inside of the e-mail.
For those with ads running through the site, I apologize for this error and will keep an eye on the mails for the next few days to make sure that it stays working correctly. If your e-mail was scheduled to go out between those times, your ad will be resent tomorrow and you will begin to get clicks.
