SES Complaints Rate in Reputation metrics

Question

Hello, We have setup the SNS to handle bounces and complains and we have been monitoring the notifications to take remove those emails from our list. However, we have encountered a discrepancy where CloudWatch metrics are displaying complaints without corresponding notifications from SNS. For example, over the past two days, we received only 2 complaints notifications through SNS, yet CloudWatch is showing a much higher count of around 50 complaints during the same timeframe.

Can you provide any insights into why CloudWatch metrics are reflecting complaints that were not received through SNS?

Answer

Hello,

In general, make sure that the metric namespace, name, and dimensions being used to filter the metric match what SNS is publishing to CloudWatch. Another reason this may happen is that if you have made recent configuration changes to the SNS service, temporary or duplicate metrics may have been published during that period. It can take CloudWatch some time to remove these non-repeating metrics.
