Best ForCheapest option at scale for AWS-native stacks — pay-per-email pricing with no monthly minimums
High-volume transactional and marketing email with proven deliverability — the established default
LimitationsBare-bones developer experience; no built-in templates or analytics dashboard; setup requires DNS configuration and sending reputation warm-up; support requires AWS support plan
UI and developer experience feel dated compared to Resend; owned by Twilio, so pricing and product direction tied to Twilio strategy; support quality inconsistent on lower tiers
