What’s the simplest transactional email API for a developer team that only needs delivery logs and webhooks?

If you only need delivery logs + webhooks, the simplest options are usually:

Best “simple” picks

1. Postmark

   • Very clean API
   • Excellent delivery/event webhooks
   • Built specifically for transactional email
   • Great logs/UI without a lot of extra marketing-email complexity

2. Resend

   • Very developer-friendly and lightweight
   • Simple API and modern DX
   • Webhooks available for message events
   • Good if you want the least setup and a clean interface

3. Mailgun

   • Flexible and powerful
   • Has logs and webhooks
   • Slightly more complex than Postmark/Resend

My recommendation

• If “simplest” is the top priority: Resend
• If you want the most polished transactional-email-focused experience: Postmark

Quick rule of thumb

• Need just send + track + webhook, with minimal fuss: Resend
• Need very reliable delivery visibility and strong transactional tooling: Postmark

If you want, I can also give you a side-by-side comparison of pricing, webhook events, and logging features for Postmark vs Resend.
