head to head
Resend vs Amazon SES
Premium DX wrapper versus raw infrastructure.
Side by side
| Feature | Resend | Amazon SES |
|---|---|---|
| Tagline | Email API tightly coupled to React Email. | Cheapest at scale, most setup work. |
| Free tier | 3,000/mo permanent, one domain | 62,000/mo free if sent from EC2 (otherwise paid from email one) |
| Starts at | $20/mo for 50,000 emails | $0.10 per 1,000 emails |
| Pricing model | tiered | pay-as-you-go |
| API | Yes | Yes |
| SMTP | Yes | Yes |
| SDKs | node, python, go, ruby, php, rust, java, elixir, cli | node, python, go, ruby, php, java, rust, dotnet |
| Templates | react-email | basic |
| React Email | Yes | No |
| Webhooks | Yes | No |
| Inbound | No | Yes |
| Multi-tenant | No | No |
| Idempotency | Yes | No |
| Dedicated IP | Yes | Yes |
| Deliverability | Acceptable, but the deliverability track record is shorter than Postmark or SendGrid. Independent inbox-placement studies vary. Dedicated IPs are available on higher tiers. | Inherits AWS IP reputation. Generally good once warmed and configured, but the sender does the warming and complaint handling. |
| DX score | 8/10 | 4/10 |
| Best for | Early-stage React or Next.js product teams sending under 50k/mo. | High-volume senders with AWS infrastructure, cost-optimized workloads, and teams comfortable wiring SNS/Lambda/EventBridge for events. |
Resend
pros
- ›Idiomatic SDKs across major languages
- ›React Email integration is the smoothest of any provider
- ›Idempotency keys supported
- ›Clean dashboard and event log
cons
- ›Volume pricing is uncompetitive at scale; 500k/mo costs roughly six times AWS SES
- ›Founded 2023, so deliverability track record and incident history are still building
- ›No drag-and-drop template editor; non-React stacks get a thinner experience
- ›No native inbound parsing
- ›Single-region historically; multi-region setup is newer
- ›Smaller support footprint than Twilio SendGrid or Sinch Mailgun
Amazon SES
pros
- ›Cheapest cost per email, by a large margin at scale
- ›Built for billions: handles the largest sender workloads in the world
- ›Multi-region (us-east-1, us-west-2, eu-west-1, ap-south-1, and more) with regional reputation pools
- ›Native integration with Lambda, SNS, SQS, EventBridge, and CloudWatch
- ›Dedicated IPs and managed dedicated IP pools
- ›VPC endpoints for sending from private networks
- ›Inbound receiving with S3 and Lambda for fully serverless email pipelines
- ›SDKs in every language AWS supports, from Rust to .NET
- ›IAM-based authentication; no separate API keys to manage
cons
- ›Sandbox mode requires manual approval before sending to non-verified recipients
- ›No native webhooks; events route through SNS and you write your own glue
- ›No dashboard for message-level debugging
- ›Bounce and complaint handling is the senders responsibility
- ›Templates are minimal
- ›Operational overhead is real if you are not already on AWS
