What Customer.io is good at

  • Automations that react to an event, a segment or a schedule.
  • One platform for email, push, SMS, in-app messages and webhooks.
  • Models people and the objects they relate to, such as accounts, for targeting.

Where Customer.io breaks

  • Billing is on the maximum number of profiles in the account; reviewers note you pay for all contacts whether active or not.
  • Reviewers say the UI can feel overwhelming at first, especially for non-technical users.
  • Overage is charged at $0.009 per extra profile and $0.12 per extra 1,000 emails.

When a custom build beats Customer.io

When you send a few fixed lifecycle emails off a handful of events, a cron job plus a transactional email API is cheaper and simpler.
