Our work

Your brand is not a template. Neither is your lifecycle.

Every campaign and flow is built from your customers, your catalogue and the way your buyers actually decide - so the programme fits the brand it is selling for.

  • Full-length email design: a product education campaign for a supplement brand.
  • Full-length email design: a subscription club launch campaign.
  • Full-length email design: an editorial campaign pairing content with a sitewide offer.
  • Full-length email design: a buy-one-get-one promotional campaign.
  • Full-length email design: a free-gift offer with cross-sell blocks.

What we run

Three owned channels. One retention system.

Every email, SMS and WhatsApp message is tied to where a customer is in their journey - and to what actually moves them to buy again.

How the three channels connect Email, SMS and WhatsApp all feed one set of lifecycle programs. Email SMS WhatsApp Lifecycle programs Flows · Campaigns · Segments
Three channels, one customer record. Cohorts, LTV and behaviour decide what gets built, for whom and when - so retention compounds instead of guessing.
01

Email

The revenue engine of retention.

Most of the repeat revenue we recover comes through here. Lifecycle flows and campaigns built to compound - welcome, browse, cart, post-purchase and win-back - with the segmentation, creative and testing that turn the inbox into your most profitable channel.

  • Lifecycle flows
  • Campaign strategy
  • Segmentation
  • Creative & copy
  • A/B testing
02

SMS

The other half of that engine.

Immediate, personal and high-intent. Behavioural journeys and campaigns that respect the channel - tight segmentation and automation that drive repeat orders and reactivation without burning the list or the brand.

  • Campaigns
  • Segmentation
  • Compliance
  • Conversion focus
03

WhatsApp

Where the conversation continues.

Layered in for brands whose customers already live there. Personalised, automated journeys and opt-in messaging that turn a near-100% open rate into genuine two-way engagement, loyalty and repeat revenue.

  • Lifecycle journeys
  • Broadcasts
  • Personalisation
  • Two-way
  • Opt-in offers
-

One customer record behind all three.

The channels are not three programs. They are one program with three ways of arriving - which is why a customer never gets the same message twice, in two places, on the same day.

The retention engine

Every customer is on a journey. We design what happens next.

The gap is the whole business case. Acquisition buys the first order; the lifecycle decides how many follow - and every order after it lands on a customer you have already paid for.

How we work

From a first call to a programme that pays for itself.

  1. 01

    Discovery call

    Thirty minutes on your account rather than a pitch. What you sell, who buys twice, what has already been tried and what it cost.

  2. 02

    Retention audit

    We go into the account and put a number on the gap. Cohorts, lifetime value, flow coverage and campaign history - so the problem is measured before anyone proposes a fix.

  3. 03

    Your 90-day roadmap

    Every move we would make, sequenced and ranked by the revenue it should return, with the reasoning attached to each one.

  4. 04

    You choose to work with us

    The audit and the roadmap are yours either way. If we are not the right team to build it, you still leave knowing exactly what to build.

  5. 05

    Onboarding and your team

    Access, deliverability, tracking and brand, inside a week. The senior people who ran the audit are the people who build it - nothing is handed to a junior.

  6. 06

    Execution

    Flows, campaigns, segments and creative shipping to a calendar you can see, across email, SMS and WhatsApp - written, designed, built and QA’d in house.

  7. 07

    Ongoing management

    Test, cut what is not earning, reinvest in what is. Every month you get a plain read on what the programme returned and what moves next.

Good retention leaves a trail.

Case 01

Email · 12 months

$1.36M attributed to email across twelve months.

Email generated 33.9% of the brand’s total revenue, $832K from campaigns and $526K from automated flows. We got there by rebuilding the core lifecycle flows, tightening audience segmentation, and creating a consistent campaign strategy around customer behaviour, not constant discounts. The result was a retention system that knew who to email, what to send, and when to hold back.

Case 03

Email · 30 days

$62,703 from email in the first full month.

We don’t send emails to fill a calendar. We send them with a job to do. Every campaign is built around a clear audience, commercial objective, and reason to buy. In one 30-day period, that approach generated $62.7K from email, 56% of the brand’s total revenue.

In their words

Retention our clients can feel.

  • We’ve worked with two agencies before this one. The difference here is that things ship on time and I don’t have to chase anyone. Copy and design come back together, on brand.
    Andrew Hogan Marketing Head
    Juna
  • They went through our customer data and showed us who was worth talking to, and how often. The win-back and replenishment flows they built off that have performed well beyond what we expected.
    Mariela Rodriguez Founder
    Costazul Beauty
  • Our core flows hadn’t been touched in two years. Retain Matters rebuilt the whole journey in Klaviyo, and the post-purchase side now runs without anyone on our team managing it.
    Kiley B Founder
    Rejuran Cosmetics
  • They took the time to understand how we talk to customers, and the team is fast with feedback on tone of voice. The monthly report is one page and I actually read it.
    Joshua Clifford Founder

Why Retain Matters

Not another agency running your Klaviyo account.

Retention-first, always We start where most agencies stop - after the first sale, where the margin actually lives.
Senior operators only The people who audit your account are the people who build it. No account-manager relay.
Data before opinions Cohorts, LTV and RFM drive the decisions. We can defend every flow with a number.
Owned channels, not ads Email, SMS and WhatsApp - revenue you own and control, not rented from an ad platform.

Our capabilities

The full flow map - welcome, browse, cart, post-purchase, replenishment, loyalty, win-back and sunset - designed against your customer’s actual buying rhythm rather than a platform template, then built, QA’d and monitored.

A planned calendar with a reason behind every send - segment, offer, angle and the number it is meant to move. Fewer sends, better targeted, is almost always the higher-revenue answer.

Cohort, RFM and LTV modelling that turns a list into a set of decisions: who is worth winning back, who should never see a discount, and where the next order is most likely to come from.

Design and writing built to your brand, not swapped into a stock layout - modular templates your team can actually reuse, with copy that sells without discounting the brand away.

Authentication, list hygiene, sunset policy and reputation monitoring. The most expensive retention problem is the one where the program is fine and the mail is not arriving.

Klaviyo builds and migrations from Mailchimp, Omnisend, Attentive or Postscript - flows, segments and historical data moved on a deliverability-safe ramp so you do not lose sender reputation in the move.

A running test programme on the things that actually move money - offer, timing, segment, subject - with a monthly read on what each change was worth.

Who we work with

If you have customers, you have retention to win back.

We work with DTC brands of every size, on whatever platform they already run. Small and growing is welcome. There is no revenue floor and no checklist to pass - the audit tells both of us in 30 minutes whether there is enough there to be worth doing.

Questions

The things people ask first.

Still not answered?

Most questions are really one question: would this work on my account? The audit answers that in 30 minutes, with your own numbers, before you commit to anything.

Or email hello@retainmatters.com

DTC ecommerce brands of any size, on any platform. If you are trading and have customers coming back - or you want them to - retention is where we add the most value.

Klaviyo is our primary email and SMS platform, and we work across Attentive, Postscript, Braze, Recharge, Smile.io and Shopify. Our strategy is built around customer behaviour, not a single tool.

Both. Strategy, roadmap, flows, campaigns, segmentation, creative, optimisation and reporting - end to end.

Yes. We can improve what you already have, or rebuild the lifecycle architecture when it is holding revenue back.

Usually a free audit first, then a strategic project or an ongoing retention partnership - scoped to your customer base, not to a fixed number of emails a month.

The first flows and quick wins typically ship within weeks; retention compounds from there, and you get a monthly read on what the programme is returning.
