Amazon SES calculates the complaint and bounce rates based on a representative volume of emails. This volume represents your typical email sending practices. To be fair to both high-volume and low-volume senders, this value is different for each customer and changes according to your sending patterns. For more information, see [Bounce Rate Notification](https://docs.aws.amazon.com/ses/latest/dg/reputationdashboardmessages.html).
