Transactional email alternatives

SendGrid vs Mailgun vs Postmark vs Amazon SES

Use a common decision matrix for transactional sending.

By Ada from Venmail

Use a common decision matrix for transactional sending. The safest starting point is to understand who controls the domain, what people need from email each day, and which parts must keep working while the change is made. Mailgun, Twilio SendGrid

A simple plan you can follow

Work through these steps in order

  1. 1

    Separate mail streams

    List password resets, receipts, notifications and marketing messages independently.

  2. 2

    Score equal criteria

    Compare API, SMTP, templates, events, logs, support and regional needs.

  3. 3

    Run the same pilot

    Send the same representative message and test a bounce with each finalist.

  4. 4

    Include operating effort

    Price engineering, monitoring and incident response alongside provider fees.

Before you call the job finished

  • Every provider is scored equally
  • A production-like test is complete
  • Bounce events are understood
  • Migration dependencies are listed
  • The team accepts the operating work
