The retention system
Built for the whole journey. Run as one system.
Every stage of the customer journey, from first capture to true retention. Not a stack of tactics. One engine, every part pulling in the same direction.
The journey, end to end
Five stages. One system running through them.
Stage 01 · Capture
Turn visitors into subscribers.
List growth done right, captured well, feeding everything downstream. The top of the funnel is the part of the program that quietly compounds everything else, so it gets the same attention as every flow that follows.
Stage 02 · Welcome & first purchase
Convert the new subscriber into a first order.
The first ten days decide whether someone becomes a customer or a quiet unsubscribe. Welcome, browse abandon, and cart abandon are built as one continuous arc, not three separate flows.
Stage 03 · Repeat & nurture
Drive the second and third order.
Post-purchase flows that earn the next purchase, paired with campaigns wired into active segmentation. Not blast-and-pray. Campaigns that progress the customer through the journey based on what they actually did.
Stage 04 · Loyalty
Turn repeat buyers into advocates.
The customers who keep coming back are the customers worth talking to most. Segmented campaigns paired with loyalty, reviews, and referral integrations. The system rewards the people who already chose you.
Stage 05 · True retention
The compounding outcome.
When the first four stages run cleanly, you stop needing a winback program. Customers keep buying because the system never let them drift. That's the version of retention we measure ourselves on. Not how many lapsed buyers we recovered, but how few we lost in the first place.

The foundation
Three capabilities that run underneath every stage.
Not stops on the journey. The ground it runs on. The work that makes every stage above actually pay off.
F1
Deliverability
Built deliverability systems from scratch, recovered domains, handled the hard cases. If mail does not land, no stage works.
- DMARC, SPF, DKIM, audited
- IP warm-up, scheduled
- Domain recovery on the hard cases
F2
Personalization
Our proprietary 1:1 hyper-personalization at scale. Built in-house when nothing on the market did the job.
- 1:1 product blocks across thousands of variants
- Plugs into Klaviyo, Omnisend, Shopify

F3
Integrations
The connective tissue. Subscriptions, loyalty, SMS, reviews, quizzes, and more. Platform-experienced beyond Klaviyo: Omnisend, Mailchimp, Nudge, and others.
- Klaviyo Gold Master Partner
- Omnisend Partner
- Shopify, Recharge, and the wider stack
1:1 personalization, at the scale of your list.
Every block, every subscriber, every send. Product picks, copy slots, hero imagery, all generated for the individual on the open. Across thousands of variants without a designer touching each one.
We built it because nothing on the market did the job. It plugs into your existing Klaviyo or Omnisend stack. It is included with your retainer, not sold separately.

Common questions
The questions we get most.
If yours is not here, ask it on the call. We will not dodge it.
Book a free consultationD2C brands that treat email and SMS as real revenue channels, not an afterthought. We work across the range: brands building their first serious lifecycle program, and established brands whose retention has stalled and needs a rebuild. If you sell direct to consumers and want owned-channel revenue that compounds, you are in the right place.
We build and run retention programs end to end: subscriber growth, the full library of lifecycle flows, campaigns, segmentation, deliverability, and our proprietary personalization engine. Email and SMS, run as one system rather than two separate channels. We handle the integrations around it too, from loyalty to reviews to subscriptions.
Most brands have something running. The real question is whether it was designed or just accumulated over time by different hands. We go back to the architecture, find the revenue your current setup is leaving on the table, and rebuild it so every flow and campaign pulls in the same direction. A starting point usually means results come faster, not slower.
The first wins usually land within the first few weeks, often from flows that were missing or underbuilt. The compounding part, where retention revenue climbs quarter over quarter, is a longer game. We measure it weekly and review it with you, so you are never guessing.
We scope plans to your brand's stage and goals rather than forcing you into a fixed tier. The simplest way to get a real number is a short call: tell us where your program is now and where you want it to go, and we will walk you through the plan that fits.
D2C and ecommerce across beauty, apparel, supplements, food and beverage, home, wellness, and more. The retention principles hold across verticals; what changes is the creative and the lifecycle timing, which we build to each brand. To see work in your category, the Showcase page is filterable.
You work with a team of specialists, not one generalist stretched thin across accounts. Strategy, copy, design, and deliverability are all in the room. You get a weekly review of what shipped and what it earned, and the people who build your program are the same people you talk to.
We do not sell guarantees, because anyone who promises a fixed number before seeing your data is guessing. What we commit to is the standard of the work and the rigor of the measurement. We treat retention with the same accountability as paid media: measured weekly, reviewed openly, owned by us.
We are a Klaviyo Gold Master Partner and an Omnisend Partner, and we work across Shopify, Recharge, and the wider D2C stack. We also have hands-on experience with Mailchimp, Nudge, and other platforms. If you are on something less common, ask us, we have likely worked in it.
Yes. Our Synergy plan is built for exactly that. We supplement your in-house team and cover the areas where they need depth, whether that is deliverability, flow architecture, or design throughput. You keep ownership; we fill the gaps.
Yes. Our Off Season plan is built for brands with a clear peak. We maintain the program through the slow period, ramp it up ahead of the season, and deliver through the window that matters most to the business.
