Amazon SES alternative for transactional email
SES is powerful and operationally heavy. SuperSend TX is the productized transactional email layer: API keys, domain verify, webhooks, and owned mail servers — with Dedicated when you need real isolation.

At a glance
Mail as a product, not a cloud project
Keep AWS when you want raw control. Choose SuperSend TX when you want domains, keys, activity, and deliverability ops without assembling them yourself.
| Attribute | Amazon SES | SuperSend TX |
|---|---|---|
| Interface | AWS SDK / SMTP / console | HTTP API + npm SDK + dashboard |
| Auth | IAM / SMTP creds | stx_ API keys |
| DX | You assemble the product | Domains, keys, activity included |
| Pipe | AWS shared / dedicated options | Owned Pool or Dedicated |
| Best when | You want raw AWS control | You want transactional mail as a product, not a project |

Infrastructure we operate
Pool is our shared transactional network for paying customers. Dedicated provisions managed servers and IPs for your workspace.
Dashboard + API built in
Domain verify, API keys, activity, suppressions, and webhooks without stitching five AWS services.
Owned Pool or Dedicated
Send on our transactional network, or book Dedicated for your own managed servers and listed IPs.
Developer surfaces
HTTP, npm SDK, CLI, SMTP relay, hosted MCP, and Agent Skills — one account across all of them.
Ops without the console tax
Bounce handling, complaints, suppressions, and deliverability signals land in one place.
