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
Ahrefs
- The entry Lite plan is $129 a month and caps projects at 5 and tracked keywords at 750
- Crawl credits are metered by tier, from 100,000 on Lite to 1,500,000 on Advanced
- Enterprise at $1,499 a month requires an annual commitment
- Brand Radar AI, custom prompts and Content Kit are separate add-ons starting at $199, $50 and $99 a month
- The $29 Starter plan covers search and competitive research basics rather than the full toolset
