Yapla has added this option to ensure that a user does not use the software to send spam, thereby penalizing other customers using the application. A customer with an abnormal complaint rate will be quickly notified. However, you don't have to worry if you receive a complaint from time to time, this is considered normal and will not be penalized.
The number of complaints received for each newsletter is visible in the "Recent Newsletters" section of your dashboard, as well as in the details of each newsletter.
Contacts who clicked on the "Spam complaint" link will be automatically unsubscribed and cannot be re-subscribed.
