Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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
Surfer SEO
- Entry Discovery plan at $49 per month limits users to a single seat and 120 documents
- AI prompt tracking is excluded on the Discovery plan and capped at 25 prompts weekly on Standard, 50 daily on Pro
- Unlimited documents on the Peace of Mind plan are subject to a fair usage policy rather than being truly unlimited
