Transactional email

Sending password resets, receipts, magic links. Avoid SES if you don't want to fight a deliverability battle.

ResendFREE TIER

free 100 emails/day, then $20/mo for 50k
The current best-in-class for indie SaaS. React Email integration, clean dashboard, no setup hell. The free tier covers most early-stage SaaS.

PostmarkFREE TIER

free 100 emails/mo, then $15/mo for 10k
Best deliverability in the industry. More expensive at scale than Resend but every email actually arrives, including the password reset to your most paranoid user.

SendGridFREE TIER

free 100 emails/day, then $19.95/mo
Twilio-owned. Bigger surface, more features, also more clunk. Use if you need their templating UI or are already on Twilio.

Amazon SESFREE TIER

$0.10 per 1k emails
Cheapest at scale by an order of magnitude. Worst onboarding experience: sandbox mode, deliverability tickets, IP warm-up. Only worth it once you're sending tens of thousands per day.
