The Amazon SES Enforcement notification is for most of the bloggers who use Amazon SES an unexpected notification that requires an immediate action if you don’t want to lose your access to the Amazon SES account.

What are the important concepts to understand about this enforcement action from Amazon.

Amazon monitors your sending behavior every time. Having a high bounce rate can cause your account to be suspended temporarily or permanently.

Amazon expects their senders to have a bounce rate below the 5%. Bounce rate higher than this percentage is considered bad and if you have a higher bounce exceeding 10% causes your account to have a high risk for suspension.

The bounce rate is based on the number of hard bounces (notices that the address you tried to send to does not exist). Soft bounces instead are not included when Amazon calculates the sending statistics. Sending to domains you have verified is also not considered in this calculation. A high bounce rate generally indicates problems with mailing list management that needs to be resolved if you want to reinstate your account at Amazon SES for the data center under risk.

Common reasons why you could be having a high bounce rate:

  • Your email list have old email addresses.
  • You don’t have a double opt-in mechanism enabled for your account.
  • The signup process on your website do not control for invalid email addresses.

A high bounce rate is interpreted by most mailbox providers as a sign that the sender is not properly managing their email list, for this purpose having a cleaned list and taking routinary actions to clean your list, is considered a best practice. This is where Unmailable can help you, especially if you do not have other mechanism in place to validate your email list on your systems. Sending unsolicited email is a signal  that mailbox providers take seriously. Amazon SES also takes this signal seriously and takes action when bounce rates are high, exceeding the 10% threshold.
