What is Suppression list?

In SES, a suppression list records recipient addresses whose messages are withheld when the configured suppression reason matches.

Who this applies to#

  • This is a concrete Amazon SES provider example of suppression

What Suppression list requires#

  • SES account suppression can use bounce, complaint, or both reasons and is scoped to account and region

What this does not require#

  • Gmail complaint data is unavailable to SES and only hard bounces are added for bounce suppression

Common mistakes#

  1. Turning a provider example into a universal database mandate

Suppression list checklist#

  • Configure reasons
  • Preserve account and region scope

Commonly confused with#

OnVoard's take#

Suppression is a delivery-control concept whose exact reasons and scope belong to the provider that owns the list.
