Email Marketing Agency Turning Quiet Databases Into Predictable Revenue

The Klaviyo email marketing agency ecommerce brands trust to turn a quiet subscriber list into a consistent, profitable revenue channel.

Read more about our approach

Most ecommerce brands are sitting on a customer database that could be generating far more revenue than it currently is. Generic campaigns, a handful of basic automations, and no real segmentation leave lifetime value and repeat purchases on the table every single month.

As a Klaviyo-focused email marketing agency for ecommerce brands, we turn underused email and SMS channels into a predictable revenue engine, combining automation, segmentation, and lifecycle strategy to build systems that drive consistent, profitable growth.

What Founders Say About Working With Us

Real written reviews — from the founders who make us the email marketing agency London ecommerce brands recommend.

★ ★ ★ ★ ★
“Our Meta ROAS increased from 1.5x to 3x

“We were spending heavily on Meta but struggling with efficiency. Rozee Digital helped us rebuild the account so we could scale confidently. Our Meta ROAS increased from 1.5x to 3x while spending six figures per month, without the usual instability.”

JessFounder, Cocopup

“$1M+ in monthly revenue in just 70 days

“We were already doing around $300k/month, but scaling always came with volatility. Rozee Digital helped us break through to $1M+ in monthly revenue in just 70 days while actually improving ROAS, not sacrificing it. The biggest difference was how disciplined they were around scaling decisions.”

SteveCOO, Alp N Rock

“Easily the best agency experience we’ve had”

Sound Familiar?

You've been here before

You hired an agency that promised the world. Three months in, campaigns still get sent to everyone the same way, the welcome flow is basically untouched, and open rates look fine while revenue barely moves.

You don't have an email problem. You have a system problem — no segmentation, no flow strategy, no structure built to turn a quiet list into repeat revenue.

That's the problem Rozee Digital was built to fix.

Our list is huge but revenue per email barely moves the needle.
We've got a welcome flow and basically nothing else built out.
Every campaign goes to the whole list, no segmentation at all.
Deliverability tanked and nobody can tell us why.
Abandoned cart emails go out but conversion is still weak.
Klaviyo feels like a mess nobody's cleaned up in over a year.
SMS is a total afterthought bolted onto email.
Unsubscribes creep up every time we run a promo.
We can't tell which flows actually drive revenue vs. just opens.
Winback and post-purchase flows simply don't exist.

The Work

The Flows Behind The Revenue

Every result on this page starts with a flow. Here's how our email team turns your Klaviyo account into an automated revenue engine.

First

Welcome automation

Strategic timing and product-focused messaging built to convert new subscribers into first-time buyers, introducing your brand and driving fast initial purchases.

Second

Abandoned cart recovery

Behavioural triggers, timely reminders and urgency-driven copy that bring customers back to checkout and recover lost sales without extra ad spend.

Third

Post-purchase & loyalty

Tailored follow-ups and product recommendations that increase repeat purchases, strengthening relationships and turning one-time buyers into loyal customers.

Fourth

Winback & reactivation

Personalised messaging and exclusive offers designed to reactivate inactive subscribers, reducing churn and bringing dormant customers back into the revenue cycle.

Our Email + SMS Growth Ecosystem

Modern retention marketing is no longer just about sending email campaigns in isolation. As a performance-driven DTC marketing agency, we build an integrated ecosystem across email and SMS to maximise engagement, revenue per customer, and conversions at every stage of the lifecycle.

Unified Email + SMS Strategy

We don't treat email and SMS as separate channels. Campaigns and flows run seamlessly across both for consistent messaging, stronger brand recall, and improved conversion opportunities through multiple touchpoints.

Segmentation Across Behaviour & Lifecycle

We segment by purchase history, browsing behaviour, engagement level, cart activity, and customer lifecycle stage, so every message reaches the right subscriber at the right time.

Full Lifecycle Retargeting System

We implement advanced flow logic that follows subscribers across email and SMS, re-engaging them with personalised messaging designed to move them closer to conversion.

Send-Time & Channel Optimisation for Scale

We continuously optimise send times, frequency, and channel mix, ensuring messages land where your audience is most responsive — improving open rates, CTR, and overall revenue efficiency.

Tracking & Technical Setup: The Foundation of Our Email Marketing Services

Klaviyo Setup & Integrations

We begin by setting up and auditing your Klaviyo account, integrations, and tracking so every flow and campaign decision is backed by real customer and revenue data.

Deliverability & Domain Health

We monitor sender reputation, authentication, and inbox placement, ensuring your emails actually reach the primary inbox instead of getting buried or filtered as spam.

Attribution & Revenue Tracking

We configure attribution settings to measure performance correctly across flows and campaigns — understanding which sequences and segments are truly driving revenue, not just opens.

List Hygiene & Data Accuracy

We continuously monitor list health and engagement signals to keep your sender reputation strong, reducing wasted sends and scaling campaigns more efficiently over time.

Our Creative Strategy That Drives Conversions for Email & SMS

In modern retention marketing, copy and offer are the single biggest factors determining performance. As a performance-driven email marketing agency, we don't just send campaigns; we engineer messaging systems designed to capture attention, communicate value instantly, and convert quiet subscribers into paying customers.

Revenue-Focused Copywriting

We write every email and SMS as part of our wider retention strategy, built around clear value and a single strong call to action rather than generic brand messaging.

Subject Line & Preview Text Testing

The subject line decides whether an email gets opened at all. We test subject lines and preview text systematically, focused on curiosity, urgency, and personalisation to lift open rates.

Segmented Campaign Design

Every campaign is built with segmentation in mind from the start — new subscribers, repeat buyers, and lapsed customers get different messaging, not the same blast to everyone.

Structured Automation Testing Framework

Instead of relying on a trial-and-error approach, we use a structured testing system across every flow. Timing, copy, and offers are tested systematically, and performance data determines winners.

Flow Iteration for Scaling

Winning flows are not left untouched; they are continuously refreshed and improved. Our team develops new variations, timing, and offers to prevent fatigue and maintain strong performance at scale.
