Customer.io Description

Customer.io is a US software company founded in 2012 that helps businesses send personalised messages based on how customers use their product. Teams send behavioural data from their app or website, then build journeys that trigger emails, push notifications, SMS and in-app messages when users sign up, reach a milestone, stop engaging or make a purchase. A visual workflow builder, segmentation, A/B testing and a template editor support marketers, while developers can use APIs and a data pipelines product to collect and route customer data to other tools. AI features help write messages and analyse results. Customer.io is popular with SaaS companies, mobile apps and digital businesses that want more control than standard newsletter tools offer, and the company reports thousands of brands as customers. For affiliates, it suits SaaS marketing content, growth and product-led growth blogs. The partner programme pays a revenue share for the first year.
