Email tracking
From Wikanual
When you send out a notification to somebody via INTERDUBS you can track if he / she visited the site. In order do be able to do so you need to let INTERDUBS send the email.
The system will insert a unique code into the link of the mail and will cross reference the email with the visit. All logs and the email log will track the visits of the email.
If you send an email to multiple recipients then you have to select the option that lets INTERDUBS send individually emails to each recipient. Otherwise the system will not insert the tracking code.
