The short version

  • Each has a real cost: ConvertKit the free Newsletter plan allows only one basic visual automation, so sequences beyond a single flow require paying; 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

Where each one falls short

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

ConvertKit

  • The free Newsletter plan allows only one basic visual automation, so sequences beyond a single flow require paying
  • The free plan is a single user, and the Creator plan at $33 a month allows two
  • Subscriber signals, engagement analytics and paid recommendations are Pro only, at $66 a month
  • A/B testing is capped at 2 subject lines below Pro, which allows 5
  • Paid pricing is banded by subscriber count, so the published figures apply only at the smallest band

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
