We unify your data, messaging, and AI into a single platform, so every interaction with your customers is stronger and more relevant than the last.
Data first for all web and mobile channels
Leverage webhooks to integrate data seamlessly across your entire tech stack. Batch update multiple profiles, associating a single data point with various people or messages simultaneously, ensuring your data remains clean and accurate. Whether you operate in a B2B, B2C, or B2B2C model, maintain a streamlined data environment.
Powerful visual workflow builder
Build multi-channel messages within a single workflow, including email, SMS, push notifications, and web/mobile in-app messages. Set conversion goals at the campaign level to easily track performance.
Multiple workspaces
Keep audiences (leads/customers), products, countries, sites/apps organized with separate workspaces, each with relevant data and associated APIs. Use the copy campaigns feature to share workflow logic efficiently across your different workspaces.

Customers love us
Preferred by product-led companies
We were blown away by our ability to have marketers create complex automations without having to get too technical. We also have engineers in the platform and love that both departments can easily execute their visions.
Ido Schachter
R&D Tech Lead
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.
Diego Schocher
Business Architect
We know how important data is. Not only that, but to own your own data. That’s why we chose Customer.io.
