I’ve worked with many ESPs in my career, and I’ve never seen such robust segmentation and branching logic before. It’s been so critical in setting up our customer communications. Basically, anything is possible with the right logic in Customer.io, which is amazing for a data and analytics-driven team.

Customer.io’s ad audiences tool is especially beneficial on Facebook where we’re paying for each impression –– it allows us to be much more accurate and efficient with our spend.

The biggest change we’ve made is our audience segmentation. We’re now seeing which audiences are performing well and increasing budgets accordingly, and decreasing spend where we haven’t seen as much success. It’s allowed us to spend more strategically and efficiently.

What really makes Customer.io stand out is your focus on data. You make it easy to get the data we need, whether it’s sending it in or getting it out. The cherry on top is we can leverage our data to dynamically personalize our segmentation efforts and messaging.

I created a segment for people who had asked for a feature we were launching. Those emails perform really well because people know that we’re paying attention to what they've asked for.
