Strengths and weaknesses
Amazon SES- +Lowest-in-class price at $0.10 per 1,000 emails with no monthly platform fee or minimum commitment
- +Scales to millions of emails effortlessly on AWS's proven sending infrastructure
- +Deep native integration with Lambda, S3, SNS, SQS, CloudWatch, and IAM
- –No built-in dashboard for opens/clicks/bounces/complaints, you must wire up SNS/Lambda yourself
- –Sandbox mode (200/day, verified recipients only) plus a manual production-access request before real sending
- –No templating UI, campaign management, or marketing automation, purely sending infrastructure
- +First-class React Email integration, compose emails as React components that render across major clients
- +Excellent developer experience: clean REST API, fast setup (often ~30 min including DNS), clear docs and useful per-message logs
- +Generous free tier (3,000 emails/month) and simple, transparent volume-based pricing
- –Intermittent email-sending latency, recurring reports and published incidents of delayed delivery, sometimes minutes or more
- –Less mature deliverability tooling and guidance than incumbents like Postmark, especially as volume scales
- –Analytics are thinner than legacy platforms; users want deeper reporting and proactive DNS/reputation warnings
