The power of multi-channel messaging
Preferred by product-led companies
We have been using Customer.io since 2015, and it is a flexible and powerful platform. We can create customized campaigns based on how often our users walk their dogs, which makes our messaging more effective for us and our sponsors. Terrific customer support combined with their great product makes Customer.io an important partner for our mobile app.
Customer.io is the most intuitive and robust omnichannel messaging platform I’ve ever used. They beat the competition out of the water.
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.
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.
The multi-channel approach allows us to test and refine our strategies through A/B testing, helping us understand what value propositions motivate our users.
