When Customer.io wins
- B2C and B2B teams with custom objects in their data model (accounts, subscriptions, devices) who need messaging tied to those entities
- Product-led businesses sending behavior-triggered lifecycle messaging across email, SMS, and push
- Teams needing HIPAA compliance for healthcare or digital-health workflows
Where Customer.io is the wrong fit
- Solo creators and newsletter operators (Kit or beehiiv are the right shape)
- Small businesses that need a $0/month or $20/month entry point (MailerLite or Mailchimp Free fit better)
- Teams that want a one-click WYSIWYG email tool with no data modeling required
When Ghost wins
- Independent publishers who want to own their stack and keep migration optionality
- Paid-newsletter operators trying to avoid Substack's 10% revenue share at scale
- Publications that need staff seats, custom themes, and a real CMS rather than just an email tool
Where Ghost is the wrong fit
- Hobbyists who refuse to pay anything ever; Substack or Buttondown's free tiers fit better
- Podcast-first creators; Ghost is text and email native, not an audio platform
- Teams that need deep CRM, lead scoring, or marketing automation; this is a publishing tool, not a marketing-automation suite
