The trade-offs

Strengths and Limitations

Oracle Eloqua

Strengths

  • Several lead-scoring models run at once across products, business units and regions
  • Campaign Canvas and Program Canvas separate journey design from data and lead-management automation
  • More than 70 prebuilt reports plus closed-loop revenue attribution
  • More than 500 prebuilt integrations through the Marketing AppCloud

Limitations

  • No published rate card; pricing is quoted by sales
  • Aimed at enterprise B2B, so much of the machinery is idle for a simple newsletter
  • The payoff depends on a CRM integration being in place

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
