Reviewer Notes

SES has excellent agent tooling with comprehensive AWS SDKs across all major languages, well-documented APIs, and structured JSON responses that parse cleanly. Discovery is strong via AWS documentation and OpenAPI specs, and reliability is excellent with AWS's track record. The main weakness is account creation—agents cannot programmatically create AWS accounts or enable SES sandbox mode without human intervention; additionally, SES requires AWS account setup with identity verification (email/domain confirmation), which blocks autonomous operation. The free tier (62.5K emails/month) is decent but requires credit card upfront and comes with sandbox-only restrictions initially.
