The trade-offs
Strengths and Limitations
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
Salesforce Marketing Cloud Account Engagement
Strengths
- Scores, engagement history and attribution sit directly on Salesforce CRM records, with no connector between marketing and sales
- Multi-touch attribution models and B2B Marketing Analytics report campaign effect against pipeline rather than against opens alone
- Einstein covers both sides of the job, scoring prospects and drafting email and landing page copy
Limitations
- Priced per organisation from $1,250 a month billed annually, so the entry cost does not scale down for a small team
- Contact allowances are the real cost driver, and extra blocks run from $100 to $400 per 10,000 contacts and month depending on edition
- Business units cost $2,000 per unit and month on top of the edition price
- The value rests on Salesforce being the system of record, which makes it a poor fit for companies running another CRM
