About
We do one thing: make the second order happen, and the fifth.
Retention Control is a retention-only agency. No paid media, no web builds, no rebrands. Email, SMS, lifecycle automation and loyalty for Shopify and DTC brands in the US, UK, Ireland and Europe.

The agency
Retention is a full-time job, not a channel someone covers on Fridays.
Four things worth knowing before you hand anyone your list.
- 01
Why retention only
Most brands put the majority of their budget into the first order and almost nothing into the second. Retaining a customer costs roughly five times less than acquiring one, and mature lifecycle programmes contribute 30–40% of store revenue. That gap is the whole business — and it is a full-time job, not a channel someone covers on Fridays.

How we work
Every engagement starts with a free 60-minute audit and a written plan. The person on that call is the person who runs the account. Flows are built against your real order data, campaigns run on a calendar built around your seasons, and every month you get one report: what each flow and campaign earned, what moved, and what changes next.
- 03
What we will not do
We will not discount our way to a number, send to people who stopped engaging, or put a text where an email belongs. We will not take a brand under roughly $500K a year where a retainer cannot pay for itself. And we will not hold your list: everything is built inside your account, documented, and yours if you leave.
- 04
The platforms
We work on Klaviyo, Omnisend, Brevo and Attentive. Four platforms instead of one so the platform recommendation follows your catalogue and list rather than our convenience — and so a migration is an option rather than a threat.
How we work
Six steps, six weeks to live, then monthly.
The same process on every account and every platform.
Week 1
We read your account before we touch it.
Where the revenue is leaking
Every flow, every campaign, list health, deliverability, segment logic and the revenue each piece attributes. You get the gaps ranked by money, not by opinion.
- 01Flow-by-flow revenue and send volume
- 02List capture, engagement and suppression health
- 03Deliverability: domains, complaint rate, inbox placement
- 04Segment logic against actual order data
- You get: A written audit with the first 90 days planned.
Week 2
RFM segments from your orders, and a calendar built around your peaks.
Segments and the calendar
Recency, frequency and monetary tiers from real order history; lifecycle stages; a campaign calendar that starts with your seasons, not a template.
- 01RFM and lifecycle segmentation
- 02Offer ladder by segment (who gets a discount, who never does)
- 03Send-time and frequency rules
- 04Campaign calendar for the next quarter
- You get: A strategy document your team can run without us.
Weeks 3–5
The core flows, written and designed for your brand.
Flows and templates
Welcome, browse and cart abandonment, post-purchase, replenishment, win-back and VIP — each with copy, design, timing and the split tests already planned.
- 01Copy and design per flow, on-brand
- 02Trigger, filter and timing logic checked against real orders
- 03Templates your team can reuse for campaigns
- 04SMS steps where they earn their place
- You get: Flows live, documented, with QA screenshots.
Week 6
Ramped sends, warmed domains, no spike.
Go-live without a deliverability hit
New flows go live in stages so engagement stays high and the sending reputation you have is protected. Campaigns start on the calendar from strategy.
- 01Staged rollout by segment
- 02Domain and IP warm-up if needed
- 03First campaigns on the new calendar
- 04Reporting dashboard set up
- You get: Everything running, with a baseline recorded.
Monthly
Subject lines, offers, timing and creative — one variable at a time.
A/B tests with a hypothesis
Every test has a written hypothesis and a minimum sample. Winners roll into the flows; losers are documented so nobody re-tests them.
- 01Subject line and preview text
- 02Offer type and depth by segment
- 03Send time and flow delays
- 04Design and layout variants
- You get: A test log with results and the next tests queued.
Monthly
One report: what each flow and campaign earned, and what changes next.
Revenue, not open rates
Attributed revenue by flow and campaign, list growth, repeat-purchase rate, email and SMS share of store revenue — and the plan for next month.
- 01Revenue by flow and campaign
- 02Repeat rate and LTV movement
- 03List and deliverability health
- 04Next month’s calendar and tests
- You get: A monthly report and a 30-minute review call.

Questions
Frequently asked questions
How big is the team?
Small and senior. The person who audits your account is the person who builds and runs it; nobody is handed to a junior after signing.
Where are you based?
We work with brands across the US, UK, Ireland and Europe, and run on your send times rather than ours.
Do you do paid ads or web development?
No. Retention only. We work alongside your paid team and your developers, and we are happy to talk to them directly.
What size brand do you work with?
Shopify and DTC brands from roughly $500K to $5M+ a year. Below that a retainer rarely pays for itself, and we say so.
Can we see client results?
Most of our clients are under NDA, so results are published by category, platform, metric and period rather than by name — on the services pages, confirmed from the platform's own report before they go up.
