Reliable transactional email providers with API access and delivery logs include:

  • SendGrid — solid API, detailed event webhooks, message activity logs, templates, and good scalability.
  • Mailgun — strong developer-focused API, searchable logs, routing, and webhooks for delivered/opened/bounced events.
  • Postmark — excellent for transactional email specifically, very clean API, strong delivery tracking, and very good reputation.
  • Amazon SES — very cost-effective, reliable at scale, integrates with AWS services, supports event publishing/logging, but setup is more technical.
  • SparkPost — strong analytics and event data, API-first, good deliverability tools.
  • Brevo (Sendinblue) — API support and event tracking, easier to use for smaller teams.
  • Mailjet — API plus message/event tracking, decent for transactional use.
  • Resend — modern API, simple developer experience, logs/events, good for product apps.

What to look for:

  • API for sending and querying message status
  • Webhooks/event logs for delivered, bounced, complained, deferred events
  • Message search/history in dashboard
  • Dedicated IPs or domain authentication if volume is high
  • Suppression lists and bounce handling
  • Templates if you want managed transactional content

If you want, I can also narrow this down by:

  1. best deliverability,
  2. lowest cost, or
  3. easiest API for developers.
