Send email
Amazon SES
Email service that sends and receives mail through an API, SMTP or SDKs, with delivery events published to AWS services.
Methods
| Method | Used for | How |
|---|---|---|
| AWS IAM credentials (SigV4) | REST API, SDKs, CLI | Requests are signed with AWS credentials; SDKs handle signing |
| SMTP username and password | SMTP interface | Generated per region from IAM; different from the AWS secret access key |
| OAuth 2.1 | AWS MCP Server | Browser sign-in; the IAM identity needs signin:AuthorizeOAuth2Access and signin:CreateOAuth2Token |
| SigV4 through a local proxy | AWS MCP Server | AWS CLI credentials with the MCP Proxy for AWS (uvx) |
