Amazon SES gives you raw email sending at scale. Truncus gives you managed email infrastructure — synchronous delivery proof, guarantees, a durable retry queue, governance, and a dashboard — without touching the AWS Console.
Truncus sends through SES under the hood (eu-west-1 Ireland), EU-resident by default. You get SES pricing benefits without SES management overhead, plus circuit breakers that detect failures fast and surface the exact error — no silent failures.
With raw SES, you build and maintain all of this yourself. With Truncus, it's included.
Bounce handling
Automatic suppression list, no SNS/Lambda wiring
Retry queue
Durable retries with exponential backoff and dead letter
Fail-fast error reporting
Circuit breakers surface the exact SES error — no silent failures
Delivery confirmation
Synchronous send_sync instead of async SNS
Reputation monitoring
Auto-throttle on high bounce/complaint rates
Deduplication
Content-based dedup prevents double sends
Side-by-side comparison of managed Truncus vs raw Amazon SES. Where we don't have a feature, we say so.

| Operations API (durable sends) | Yes | No |
| Pre-send validation | Confidence score, spam check, domain health | No |

| Kill switch | Instant send suspension via API | Disable SES manually in console |
| Content-based deduplication | Automatic (10-min window) | Build your own |
