Pros & Cons from Real Users

Pros

  • Customer.io has helped us as an organization to raise our marketing level by supporting our management of customers, attributes and events to maintain a very organized and segmented work rhythm. It also allows us to customize reports, modify users based on their user, add or delete attributes and assign events.

Cons

  • Among the few dislikes that have been presented to us as an organization are: data collection is a slightly weak part of Customer.io.
