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
- +Transactional email is free and unlimited on any paid plan (previously ~$1 per 2,000 sends), so transactional volume never inflates the bill
- +Unified platform: marketing, product/lifecycle, triggered sequences, and transactional share one domain and one sender reputation, removing the need for a separate SendGrid/Mailgun
- +Modern developer experience: clean TypeScript/Node SDK, idempotency-key support, MJML template uploads, and well-regarded docs
- –Contact-based pricing penalizes large or dormant lists you pay per stored contact regardless of whether you email them
- –Transactional is treated as part of the broader workflow system, not a dedicated hardened delivery API less granular control than Postmark/Resend/SendGrid
- –Data variables limited to strings and numbers; no raw-HTML-at-send model (templates must live in Loops)
