Overall Satisfaction with Customer.io

We use Customer.io for both transactional and non-transactional messages to our customers. Customer.io allows us to effectively segment users into audiences and then design drip campaigns across email, automated SMS, and direct mail. It also enables one-off winback blasts. Customer.io also allows for tracking metrics (open, click, and unsubscribe rates) and running A/B tests to optimize campaign performance.

Pros

  • Easy to build audience segments.
  • Excellent UI for crafting campaigns.
  • High-quality analytics display.

Cons

  • Support Team could be better trained to be more helpful.
  • Allow monitoring of sender reputation.
  • Add the ability to QA emails across different email service providers.
  • Improved open and click rates
  • Improved conversion to final purchase
Customer.io has drag-and-drop functionality for their campaigns that is very fun and intuitive to use. The audience build functionality strikes the right balance between usability and meticulousness. They also have an array of actions -- time delays, time windows, waitUntils -- that allow you to customize the timing of messages.
Customer.io delivers better value for money.

I would highly recommend Customer.io -- I think it makes it easy to launch new campaigns, to run experiments, and to track results. If you're looking to build marketing flows, launch one-off blasts, send transactional comms / updates, or integrate with AI, then Customer.io will serve your purposes. Lastly, they're actively enhancing the platform on a regular basis, so I expect it to be even better a few months from now.
