Rules that must be followed
How can you evaluate the quality of your messages?
The quality of the messages is managed according to three criteria: single opening rate, unsubscribe rate and the number of mail classified as spam or junk mail.
This last criterion is by far the most important. Beyond 1 of 1000, you run the risk to see all your messages classified as spam (and therefore not seen by your users).
If one of these criteria is obviously abnormal, you also run the risk to see your access suspended.
