Best For
Cheapest option at scale for AWS-native stacks — pay-per-email pricing with no monthly minimums
Best-in-class transactional email deliverability — fast inbox delivery times and transparent uptime reporting
Limitations
Bare-bones developer experience; no built-in templates or analytics dashboard; setup requires DNS configuration and sending reputation warm-up; support requires AWS support plan
No free tier; strictly transactional email only — no marketing or bulk email; fewer SDK languages than SendGrid
Supported Not supported Unverified
