The trade-offs
Strengths and Limitations
Drip
Strengths
- Every feature included on every plan, with nothing locked behind higher tiers
- Deep native Shopify, WooCommerce and BigCommerce integrations with real-time data sync
- Onsite suite of popups, slide-ins and quizzes included at no extra cost
- Billed only on active people who can receive email
Limitations
- No free plan, only a 14-day free trial
- Purpose-built for ecommerce, so less suited to non-store senders
- Live chat support is reserved for the $99 / month and higher 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
