Very easy to get started with, excellent onboarding. Exactly what we needed from a customer engagement platform.
Creating the playbook is one thing. Getting it into people’s hands is another. Customer.io powered all our email flows: announcements, reminders, and nurturing sequences for everyone downloading the playbook. Their automation and segmentation made it easy to deliver the right message at the right time, without drowning people in generic blasts.
Great for building a quick event driven system.
