Still Not Getting Full Value From Customer.io?

Most brands are sitting on a powerful platform with underwhelming results. You’ve got Customer.io, but:

Your workflows are basic and you’re barely scratching the surface of what the platform can do

Event tracking is incomplete or messy, so your triggers don’t fire when they should

You’re sending campaigns, but you can’t tie them to revenue or retention outcomes

Your team doesn’t have the bandwidth or the platform-specific expertise to build what’s needed

You’re considering migrating to Customer.io but don’t know where to start

Still have questions?

Our team is here for you.

  • What level of Customer.io partnership does Propel AI hold?

    Propel AI is a Customer.io Platinum Partner, the highest certification tier. This means our team has demonstrated deep platform expertise, a track record of successful implementations, and ongoing collaboration with Customer.io’s product and support teams.

  • Can you migrate us to Customer.io from another platform?

    We build predictive churn models using engagement signals such as workout frequency, app opens, class bookings, and membership activity. When members show early signs of disengagement, automated re-engagement campaigns activate before they cancel. Prevention beats recovery.

  • Do you work with Customer.io’s journeys and visual workflow builder?

    We architect the event tracking and data layer that captures workout completions, class attendance, goal progress, and app usage. This powers hyper-personalised messaging like nudges based on missed workouts, congratulations on milestones, or recommendations based on activity history.

  • What platforms do you support?

    Yes. Whether you’re a digital fitness platform, a gym chain with an app, or a hybrid model, we design lifecycle strategies that work across your member touchpoints from in-app messaging and push to email and SMS.

  • What does ‘AI-augmented’ mean in your lifecycle strategy?

    Most fitness brands see measurable improvements in 30–60 days. Quick wins like optimised onboarding flows, dormant member re-engagement, and trial-to-paid conversion sequences deliver fast results. Our 30-day guarantee means zero risk.

  • What types of brands do you work with?

    Our strategists are supported by AI tools including our proprietary platform and Sonic AI Copilot that analyse behavioural, transactional, and engagement data in real-time. AI identifies churn risk, optimises send times, and personalises messaging at a scale manual teams can’t match. But every strategic decision is made by experienced humans.
