The short version

  • Only Google Forms has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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; Google Forms forms has no service toggle of its own and is governed by the Drive and Docs service, so an administrator cannot disable it for an organisational unit without also disabling Docs, Sheets, Slides and Drive for those same users.

What people use each for

  • Personalizing email and SMS campaigns using customer profilesnot Google Forms
  • Triggering automated messages based on user behaviornot Google Forms

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

Google Forms

  • Forms has no service toggle of its own and is governed by the Drive and Docs service, so an administrator cannot disable it for an organisational unit without also disabling Docs, Sheets, Slides and Drive for those same users.
  • Data Regions covers Forms only for data at rest and not during processing, Business Starter gets no data regions at all, and Forms is excluded from client-side encryption and unmentioned in Assured Controls, so the residency guarantees are weaker than for Gmail or Drive.
  • Google Vault has no Forms-specific retention rule, hold or export, reaching forms only as Drive files, which means survey responses are reliably retainable only when they are routed to a linked Google Sheet.
  • Adding a file upload question requires every respondent to sign in to a Google account, which destroys anonymity and excludes anyone without one, and uploaded files consume the form owner personal Drive quota rather than an organisational pool.
  • File uploads are disabled when a form lives in a shared drive, so the ownership pattern that survives a staff departure and the upload feature are mutually exclusive, and a deleted owner Drive files are recoverable for only twenty days.
