The short version

  • Only Microsoft Clarity has a free tier, so it costs nothing to try first.
  • Each has a real cost: Microsoft Clarity no paid tier means no premium support; enterprise SLAs and dedicated account management are unavailable; Postscript carrier pass-through fees are billed on top of the per-message rate, roughly $0.00418 per SMS and $0.00841 per MMS in the United States, and are routinely missing from the cost comparisons buyers build.

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

Postscript

  • Carrier pass-through fees are billed on top of the per-message rate, roughly $0.00418 per SMS and $0.00841 per MMS in the United States, and are routinely missing from the cost comparisons buyers build.
  • The cheapest per-message rates require the $500 a month plan, so a small sender pays more than double the headline low rate per text.
  • The $0 Starter plan carries a $49 minimum monthly spend, so it is not a free tier and quiet months still generate a bill.
  • US SMS marketing carries real legal exposure under consent, quiet hours and carrier registration rules, and the compliance obligation sits with the merchant, not the platform.
  • It is SMS and MMS only, so email, push and on-site messaging live in a separate tool and audience suppression between the two has to be managed across systems.
