The trade-offs

Strengths and Limitations

Moosend

Strengths

  • Marketing automation and segmentation at a lower price point
  • 30-day free trial with no credit card
  • Includes an AI Writer for drafting copy
  • Transactional email over SMTP and an API

Limitations

  • No permanent free plan, only a 30-day trial
  • Dedicated IPs, transactional email and SSO sit behind the custom Moosend+ and Enterprise plans

Postmark

Strengths

  • Message Streams keep promotional sending on infrastructure separate from transactional mail
  • Standing free tier of 100 emails a month that never expires
  • Official client libraries for eight languages plus a WordPress plugin
  • Inbound email processing on the Pro and Platform plans
  • Message data retention extendable from 45 days to 365 days on Pro and Platform

Limitations

  • No automation, journey builder or stored audiences
  • Inbound email is not included on the Free and Basic plans
  • Dedicated IPs, extended retention and DMARC monitoring are priced as add-ons
  • The free tier permits no overage, so sending stops at 100 emails
  • All three paid plans start at the same 10,000 emails, so the choice is really about overage rate
