Streamlined Messaging Automation, with Analytics Room to Grow

I like Customer.io’s reliability and intuitive interface. The initial setup was straightforward, thanks to the clear documentation, intuitive dashboard, and developer-friendly APIs. My engineering team integrated event tracking, configured customer segments, and set up automated messaging workflows with minimal friction. Compared with Infobip, Customer.io offered a smoother onboarding experience and required less configuration. It also works exceptionally well with our SaaS applications through APIs and event tracking, alongside our Next.js and Supabase infrastructure, for automating onboarding, transactional notifications, and customer engagement.

Powerful Automations and AI Agents That Save Time Across Multi-Brand Campaigns

Integration with our app events and data that support the ability to build out complex automations for targeted and personalised campaigns. Combining our work with Claude MCP, and the native AI agent, has significantly reduced time to build as well as improved monitoring of performance, issues and successes. Design templates and saved references have allowed us to brand across multiple white labels for email and in-app messaging, again saving time.
