Outsend and Amazon SES
This is the least adversarial comparison on the site, because Outsend sends through SES. The question is not which provider — it is whether you want to build the control plane yourself.
Unbeatable per-message economics
Nothing else comes close at volume. If cost per message is the dominant factor and you have the engineering time, raw SES is the rational answer.
Enormous scale and reliability
It is AWS. The sending infrastructure is not the part that will let you down.
You may already have it
If you are on AWS, the account, the IAM, and the billing relationship already exist.
We are the part you were about to build
Event storage, suppression handling, bounce classification, reputation scoring, webhook delivery with signing and retries, DKIM key management, and a UI a non-engineer can use during an incident.
Idempotency out of the box
A retried SendEmail call on a timeout sends twice. An Idempotency-Key header does not. This alone removes a class of bug most hand-rolled SES integrations still have.
You keep your AWS account
Point us at your existing verified identities and keep paying AWS directly for sending. We are the control plane, not a reseller in the middle.
If you have already built event ingestion, suppression, and reputation tooling on top of SES and you are happy with it, keep it. If you are about to, talk to us first.
We quote competitor prices in one place only. The price calculator shows each one with its source and the date we checked it. Confirm it on Amazon SES's pricing page before you decide.

Switching from Amazon SES?
The migration guide has the field map, the event map, and the checklist — including the suppression-list import everybody forgets.
