Understanding Conversion Tracking for Targeted Emails
Conversion tracking is enabled by default on your Targeted Email. With tracking turned on, your email reports will automatically include statistics on form submissions and dollars raised from this email.
If for some reason you do not want to add tracking IDs to your emails, you can disable this feature by unchecking the box on the Smart Links wizard. If you prefer not to ever track this information, you can request to turn this feature off entirely.
