Key Differentiators

How Customer.io wins

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.
