Customer.io is the most intuitive and robust omnichannel messaging platform I’ve ever used. They beat the competition out of the water.


Now we have all of the data and tools we need, which enables us to quickly build [gift notification emails] in the campaign builder with no additional engineering support required.


We use all channels in our campaigns, when it makes sense to do so. Last month we sent over 11M emails, over 5M push notifications, almost 1M in-app messages, and almost 100,000 SMS messages from Customer.io.


It allows us to visualize the whole campaign straightaway, and when it comes to analyzing a campaign by itself, I never need to do that on a workflow separately from Customer.io.


Customer.io is an irreplaceable piece for our marketing automation and operations stacks. It's flexible and powerful, yet simple and intuitive enough such that anyone on our team can build rich, diverse customer journeys with ease.


Messaging frequency is key for our strategy. We can’t email our customers daily, so increasing frequency with a multi-channel strategy is how we can scale message volume. The conversion rates prove that strategy is working.


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’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 can do what other marketing automation tools can’t—take in millions of events from users per day, segment through them almost instantly, and use any campaign action imaginable to create workflows.
