Where each one falls short

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

Alchemer

  • More expensive than the simple form builders, which is the fair comparison for a short survey
  • The interface carries a long product history and is less immediately friendly than newer tools
  • Advanced logic is powerful and correspondingly easy to misconfigure, and testing a complex survey is real work
  • Named Alchemer since 2020, so much of the searchable material still says SurveyGizmo

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
