Lifecycle Marketing, Delivered.
Multi-channel programs across email, SMS, push, and in-app
Built and run by senior strategists in Customer.io, Klaviyo, Braze, and Iterable. No junior account managers. No rip-and-replace. 30-day money-back guarantee.
Most B2C brands run an email-only program with a Klaviyo certification taped to the wall. Customers churn at Day 3. Repeat-purchase windows close before the next campaign goes out. SMS is "on the roadmap." In-app was a 2023 New Year's resolution.
The data exists. Your team is overworked, your stack is sprawling, and your last agency staffed you with a 23-year-old who learned Klaviyo on YouTube. Reporting comes back as vibes when what you need is repeat rate, LTV, and which campaigns paid for themselves.
You don't need another tool. You need a senior team that runs the program end-to-end, in your existing stack, with numbers you can defend in a board meeting.

We design and execute full-funnel lifecycle strategies inside Customer.io, welcome, onboarding, activation, re-engagement, winback, post-purchase, and loyalty flows. Every campaign is built on behavioural triggers, predictive segmentation, and AI-powered personalisation.
From scratch or rebuilding what’s broken, we handle complete Customer.io implementation including workspace configuration, event tracking setup, data architecture, workflow builds, and integration with your product, CDP, and data warehouse.
Moving from Klaviyo, Braze, Iterable, MoEngage, or another platform? We manage end-to-end migration , data transfer, workflow recreation, segment rebuild, deliverability protection, and parallel running to ensure zero revenue disruption.
We design and implement the event taxonomy and attribute schema that powers everything in Customer.io , so your automations trigger on real behaviour, your segments are precise, and your AI models have clean data to learn from.
We build custom reporting dashboards inside and alongside Customer.io that go beyond open rates , revenue attribution, cohort retention, predictive LTV, and cross-channel ROI. Every campaign is tied to a business outcome.
We monitor and optimize your Customer.io sending infrastructure, authentication setup, IP warming, list hygiene, smart suppression, and AI-driven reputation monitoring to keep you in the inbox.
From 53% onboarding lifts to 1M+ emails/month — see how we’ve moved the needle for brands like yours.

Whether Propel is the right fit for your brand, stage, and stack

Our team is here for you.
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.
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.
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.
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.
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.
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.
