How long to receive soft bounce email reply

Question

We tried sending an email on AWS SES. We received a soft bounce response from SES after several hours. How long does AWS SES send a soft bounce reply?

Accepted Answer

From [this AWS blog post](https://aws.amazon.com/blogs/messaging-and-targeting/three-places-where-your-email-could-get-delayed-when-sending-through-ses/):

> When a soft bounce event happens, SES continuously retries to deliver your email for 12 hours before giving up. There is no limit of retries during this 12-hour interval, and, as long as the ISP recovers, your email will be delivered.

From the [SES documentation](https://docs.aws.amazon.com/ses/latest/dg/notification-contents.html#bounce-types), soft bounces ("Transient") can occur for a variety of reasons. It is recommended that you [monitor your bounces](https://aws.amazon.com/premiumsupport/knowledge-center/ses-bounce-notifications-sns/) and take action based on the bounce types by analyzing the `bounceType` and `bounceSubType` fields.
