Where each one falls short

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
Instapage
- Create tier limited to 15,000 monthly unique visitors; scaling requires upgrading to Optimize tier
- Optimize tier offers only 30,000 or 50,000 visitor tiers, requiring Convert (custom pricing) for higher volumes
- Pricing significantly higher than competitor Leadpages, which offers unlimited traffic starting at $99/month
- Advanced personalisation and heatmaps only available in Convert (enterprise) tier
- Annual billing required for 20% savings; monthly billing incurs full price
