Where each one falls short

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

Customer.io

  • Essentials plan caps at 5,000 profiles (people and objects) and 1,000,000 monthly emails, with overages billed at $0.12 per 1,000 emails beyond that
  • Standard and Premium tiers show custom pricing only, and Enterprise is negotiated rate, so three of the four published tiers require a sales conversation
  • Monthly plans accept credit card only; annual billing via invoice (ACH/wire) requires the annual commitment

Plausible

  • There is no free tier, only a 30 day trial
  • Paid plans are metered on monthly pageviews, so a traffic spike moves you up a plan
  • Self-hosting is possible but means running and updating the service yourself
  • Deliberately simple, so there are no user-level profiles or funnel-by-individual reports the way a cookie-based analytics tool provides
