What counts against the SES bounce rate?

Hard bounces: permanent failures like nonexistent addresses. Soft bounces such as a full mailbox are retried and treated differently. The enforcement number is about hard bounces.

What bounce rate does AWS act on?

AWS documents review territory around 5% and enforcement risk around 10%, measured over your recent sending. Treat under 2% as the healthy zone.

Do old bounces haunt me forever?

Rates are computed over a rolling window of recent volume, so clean sending pushes old spikes out over time. The fix is stopping new bounces, which suppression does.

1
Find the source of the bounces
Look at which campaign and which list produced hard bounces. Old exports and typo-ridden signups are the usual sources.
2
Stop re-mailing bounced addresses
On sendbunny a hard bounce suppresses the address everywhere at once. Re-imports do not resurrect it. That alone flattens most bounce-rate curves.
3
Watch the trend before the next blast
Check the bounce chart and the health strip before scheduling anything large. Send to your cleanest segment first if the rate is still elevated.

What you get

Hard bounces are suppressed automatically the moment they happen.
Suppression is enforced on campaigns, the API, and test sends alike.
Bounce trends sit on the dashboard next to every campaign.
One click into your AWS from $99. SES rates when you send.

Best for

Senders watching bounce rate climb toward the threshold
Teams that just imported an old or purchased-adjacent list
Anyone replacing a partial DIY suppression setup

Not for

Senders who plan to keep mailing addresses that hard bounce
Teams without an AWS account and no plan to create one
