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

Frase

  • The entry-level Starter plan is capped at a single seat and site, which limits it to solo users rather than small teams.
  • Overage charges apply per extra article or audit page once monthly plan limits are exceeded on Professional and Scale.
  • Free trial features are limited to Professional-tier functionality for 7 days rather than reflecting the full product.
