Postmark
- Free tier caps at 100 emails per month with no overages allowed
- Basic plan ($15/mo) includes 10,000 emails then charges $1.80 per 1,000 extra; Pro and Platform tiers have their own lower per-1,000 overage rates ($1.30 and $1.20), so cost scales per email beyond the included volume
- Custom high-volume pricing above the published tiers requires contacting sales
Unbounce
- Starter tier severely limited to 5 pages and 500 monthly visitors; inadequate for most marketing campaigns
- All tiers have monthly visitor caps; campaigns exceeding thresholds require upgrading to higher-priced plans
- Optimize tier ($249/mo) capped at 50,000 monthly visitors; campaigns beyond this require custom Concierge pricing
- AI copywriting and advanced optimisation features not explicitly detailed in lower tiers
- Full customisation beyond templates requires adding custom JavaScript, CSS and HTML
- FIPS 140-2 or advanced security features not documented as available
