HOW WE WORK
Propel's three-step CLM loop.
A proprietary framework, applied across 120+ customer lifecycle builds. Average lift: 30–35% in email engagement and revenue.
Signal Identification
1
Events + attributes identify intent. Who's approaching first value, who's stalling, who's ready to adopt the next product.
Emotion-Layered Messaging
2
Each signal maps to a psychological trigger, FOMO, scarcity, excitement, reassurance, within compliance guardrails.
Feedback Loop
3
Analytics + dashboards feed back into signals. The loop compounds. Experiments run in sprints. The engine gets smarter every sprint.
OUR EMAIL + PUSH DESIGNS
Designs that convert with our retention system.
The friction with Klaviyo isn't the platform. The platform is fine. The friction is the workflow:
Design in Figma → export to HTML → load into Klaviyo → check every CTA, every UTM, every deep link. Then send. Then iterate. Most brands hit the wall here. Their strategy lives in a Notion doc. The actual emails sit in a designer's queue.
We close that gap. Senior designer on the team. Briefs to live email in 48 hours. Same operating model for Braze push notifications, in-app banners, and gamified mechanics, the kind CRED uses for spin-the-wheel and slot-machine campaigns.
HOW FAST WE MOVE
Live in your stack in 14 days.
Most agencies assign you an engagement manager and disappear for weeks. We start the audit on Day 1 and ship live flows by Day 14.

FREQUENTLY ASKED QUESTIONS
Things founders ask before booking.
How fast can you actually launch?
Day 1 is the audit kickoff. By Day 14 we ship the first live flow into production, onboarding, cart abandonment, or whichever revenue gap is highest priority from the audit. By Day 30 the full lifecycle program is running. We do this consistently. We don't assign engagement managers and disappear for weeks.
What platforms do you specialize in?
Customer.io (we're the No.1 partner globally), Klaviyo (Master Silver), Braze (Alloys partner), Iterable, MoEngage, and CleverTap. We're platform-fluent, not platform-locked. We'll work in whatever stack you already use, and won't push a migration unless your tooling is genuinely broken.
What does the 90-day guarantee actually cover?
If we don't hit ~21% monthly active lift, ~15% daily active lift, and ~32% repeat-revenue lift within 90 days of going live, you get your full retainer back. Calculated against your own baseline data, audited together at the start. It's contractual, not marketing language.
Do you replace our team or augment it?
Both, depending on what you need. Some clients have a Head of Lifecycle and want senior bandwidth on top. Some have no one and want us to run the function end-to-end. We're senior strategists, no junior account managers, no offshore execution layer. The same people who run your audit run your campaigns.
What does ‘AI-augmented’ mean in your lifecycle strategy?
Predictive segmentation, behavior-triggered flows, and content variation scoring. We use AI to make segmentation tighter and creative iteration faster — not to replace strategist judgment.
Who's actually on the team?
Senior strategists, certified across Customer.io, Klaviyo, and Braze. A dedicated lifecycle designer (the friction in Klaviyo isn't the platform, it's the design queue). An engineering bridge for event taxonomy and warehouse work. Founder-led on strategy. No part of this is outsourced.
