Overall Satisfaction with Customer.io

We use Customer.io to handle email marketing automation, in-app messaging, as well as lite CRM duties. We also use it to sync data back to ad platforms, as well as our application itself. It enables us to better engage with current customers and provide value - as well as a path to revenue.

Pros

  • Email marketing
  • In-app messaging
  • Data sync to paid platforms

Cons

  • Data analysis
  • Proactive, AI-driven campaign optimization
  • 7x ROI on email
  • 4x ROI on paid channels from synced audiences
Easy to build drag and drop email campaigns. In-app messaging needs a bit of work but has been improving.
Customer.io is easier to use and offers better bang for the buck.
