  • What is retention marketing, and why does it matter for fast-growing brands?

    Retention marketing keeps the customers you already paid to acquire engaged across every stage: onboarding, first purchase, repeat purchase, and reactivation. Acquiring a new customer costs 5 to 25 times more than keeping one, and the revenue lives in the repeat purchase, not the first order. A 5% lift in retention can raise profit 25 to 95%.

  • How is Propel different from other retention and lifecycle marketing agencies?

    Most agencies send on a calendar. Propel runs a state-driven retention system across the key moments between a customer's first order and their next one. Senior lifecycle strategists plus proprietary AI agents read live customer state (order, usage and payment) so the right message fires at the right moment. We are not a tool, we are the team, the strategy, and the execution engine, backed by a 30-day money-back guarantee.

  • What platforms and channels do you work with?

    We are platform-agnostic across the major customer engagement and email marketing tools: Braze, Customer.io, Klaviyo, MoEngage, CleverTap, Iterable, and more, plus SMS. As a Platinum Customer.io Partner and Braze Partner, we bring certified-level expertise, and we federate your product, billing, and support data into a single customer record so sends fire on real state, not a generic schedule.

  • How fast can we see results?

    Weeks, not quarters. Because the system targets specific leaks (onboarding drop-off, the first missed repeat purchase, involuntary churn), most brands see week-4 and week-12 retention move inside the first 60 days, which is why we back it with a 30-day money-back guarantee.

  • What does the engagement look like day-to-day?

    A senior lifecycle team works as an extension of yours on strategy, build, and execution, while the AI agents run routine check-ins and escalate complex threads to your team. Communication runs over Slack, with weekly performance updates and monthly strategic reviews, and your team keeps full visibility and approval on every message.

  • What if it's not the right fit?

    The journey audit is free and yours to keep, and we agree the retention metric and measurement window up front, so you are never locked into a number nobody defined. It is backed by a 30-day money-back guarantee: if it does not feel right, get your money back. No fine print, no hassle.
