Retention Marketing Agency

Acquisition brings them once.
We bring them back.

A hart returns to the same ground every season — not by accident, but because the terrain is built to draw it home. We build that terrain for ecommerce brands: the flows, campaigns and AI-driven segmentation that turn a single sale into a returning customer.

What We Build

Three systems that lead customers home

Each one works on its own. Run together, they compound — the longer an account stays under management, the more ground it holds.

The Flows

The automations that run while you sleep — engineered around your actual customer data, not a template library.

  • Welcome & signup capture
  • Abandoned cart & browse
  • Post-purchase & win-back

The Calendar

A rotating five-week send system — education, proof, brand, product, offer — so campaigns stop being reinvented every Monday.

  • Weekly rotating themes
  • A/B tested subject lines
  • Send-time optimization

The Segments

AI-driven lifecycle and engagement segments that route the right message to the right subscriber — never one blast to the whole list.

  • RFM & lifecycle mapping
  • Engagement scoring
  • Predictive churn flags
How We Work

The route back, mapped in four stops

Each waypoint depends on the last. We don't skip ahead — the ground has to be right before anything is built on it.

01
Week 1

Survey the Ground

Full teardown of existing flows, list health and deliverability. We map exactly where revenue is leaking before we touch anything.

02
Weeks 2–3

Set the Waymarkers

Core flows, signup capture and the first campaign calendar go live — copy and creative built around your actual customer data.

03
Week 4

Walk the Trail

Everything ships. We watch open, click and revenue-per-recipient daily, adjusting send times and segments in real time.

04
Ongoing

Widen the Territory

Continuous testing on subject lines, timing and segmentation. The list gets healthier — and more valuable — every month it stays managed.

Common Questions

Before you book a call

No. We audit what exists, keep what's converting, and rebuild what isn't. Most stores have a partial foundation — we finish it and systematize it.

Most clients see a measurable lift within 2–3 weeks of the core flows going live, with attribution climbing over the following quarter.

Klaviyo for email and Attentive for SMS, integrated with Shopify, WooCommerce or your existing storefront — no platform migrations required.

Yes. Strategy, copywriting and design are handled in-house, so flows and campaigns ship as a finished system, not a brief for someone else to execute.

We ask for a 90-day minimum. Retention systems compound — the value of the first month rarely represents month three.
