Where are the Spam Reports counts?

Spam Reports are part of emails "Feedback Loop". Most providers send these feedback messages back to Campaign Deputy. Google has a non-traditional feedback loop, that for privacy reasons keeps those who report an email as spam as anonymous.

You will see two percentages, one being the percentage of spam complaints received by Campaign Deputy. The second is the total percentage that includes Google's anonymous spam reports. While this number is not exact, the percentage does provide guidance on how your targeting was for a particular emails.

Google only provides this information if you send enough emails, and the data is delayed by 2-3 days. You will not see this number update until that time has passed.
