Amazon SES vs SendGrid
AWS-native unit cost versus the established managed all-in-one.
What matters for growth and lifecycle teams
Growth work lives or dies on targeting and measurement. What matters is whether behavioral triggers can be built without engineering time, whether the event stream supports attribution past the open, and whether deliverability holds when broadcast volume shares a reputation with product email.
| Priority | Amazon SES | SendGrid |
|---|---|---|
| Scheduling | No | Yes |
| Event stream | Yes | Yes |
| Deliverability | Inherits AWS IP reputation. Generally good once warmed and configured, but the sender does the warming and complaint handling. | Established delivery infrastructure, but shared-IP reputation can vary and the product is broader than pure transactional delivery. |
| Operating since | 2011 | 2009 |
| Suppressions API | Yes | Yes |
| Best published rate per 1,000 | $0.10 | $0.40 |
| Multi-tenant | No | Yes |
| Free tier | Up to $200 in AWS Free Tier credits for new accounts | 60-day free trial only (permanent free tier was removed May 2025) |
| Starts at | $0.10 per 1,000 emails | $19.95/mo for 50,000 emails |
For lifecycle and activation work running behavior-triggered journeys, broadcasts, and winback campaigns measured on revenue, SendGrid takes scheduling, operating track record, and multi-tenant support, while Amazon SES takes best published rate per 1,000. On free tier, Amazon SES offers Up to $200 in AWS Free Tier credits for new accounts against 60-day free trial only (permanent free tier was removed May 2025) from SendGrid. That ordering reflects this audience. Weigh the same table differently and the answer changes.
