Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Microsoft Clarity

  • No paid tier means no premium support; enterprise SLAs and dedicated account management are unavailable
  • Dependency on JavaScript tracking; websites with strict CSP (content security policy) may struggle with integration
  • Session replay is limited to browser-based interactions; native app behaviour in web wrappers is not captured
  • AI Chat and summaries require adequate session volume; low-traffic sites lack sufficient data for meaningful pattern detection
  • Privacy masking is automatic but lacks granular configuration; custom masking rules for proprietary data require workarounds

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
