Preferred by product-led companies
After evaluating Customer.io and Braze head to head, we decided to go with Customer.io for the ease of integration, transactional messages, our mobile capabilities, especially push notifications, and for the support, we know we would get.
Customer.io is so intuitive that anyone in our organization can understand how to use the platform. Being able to build and launch complex automated campaigns with a small amount of resources is phenomenal.
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.
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.
