The short version

  • Only Ghost 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; Ghost backup and migration processes have significant limitations and are problematic for long-term users

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

Ghost

  • Backup and migration processes have significant limitations and are problematic for long-term users
  • Open-source version lacks automatic backups, email subscriptions, and ad placement features
  • No built-in e-commerce functionality; separate platform required for product sales
  • Smaller community compared to WordPress, making support and resources harder to find
  • Narrow focus on publishing limits use cases outside content-only websites
