Customer.io lets you trigger more engagement with relevant messages based on what customers are doing in your product.
A light integration sends the Customer.io platform customer behavior data from your web or mobile app. Then you can start sending emails, push, SMS, webhooks, and even letters! All based on what users do or don't do after they log in. Increase engagement, revenue, and customer success. Remove the heavy burden on engineering to make changes and export data. You’ll create new messages faster, and get real-time results on how every message is performing.
