RetainCRM

Retain customers and grow their value over time.

Your Klaviyo Partner agency: a clean database, a newsletter calendar built around your key moments, and messages that go out on their own, at the right time.

Acquiring a new customer is expensive. Bringing one back costs far less.

A returning customer costs nothing more to acquire. They are what makes growth profitable. OMOSA data: 35% of revenue comes from returning customers, on average across the 50 fashion and lifestyle brands supported since 2024.

We don’t just send your emails. We make the decisions.

  • Who to write to, and who not to.

    A segmented list: your best customers, new ones, those drifting away. We don’t send everything to everyone.

  • What to send, and when.

    A calendar built around your key moments: 8 to 12 campaigns a month, not one more just for volume.

  • Which automations to build first.

    Welcome, abandoned cart, post-purchase: the ones that bring in the most, before the others.

  • Email, SMS or WhatsApp.

    The right channel for the right message: SMS and WhatsApp for what is urgent, email for the rest.

Every send is judged on what it brings in.

  • Three pillars, one system.

  • Foundations

Your audit starts here.

  1. The call

    30 minutes with Axel to understand your business. At the end of the call, we set up access together: Shopify, Meta, Google Analytics, Klaviyo.

  2. The analysis

    Within a few days, we cross-check your platforms: what they report, and what you actually earn.

  3. The debrief

    30 minutes and a document you keep: what we saw, and five actions for the next 30 days. No commitment.

Is OMOSA a Klaviyo agency?

Yes. OMOSA is a Klaviyo Partner. Almost all the brands we work with are on Shopify and Klaviyo: these are the two platforms we know best.

What does a Klaviyo agency do for an eCommerce brand?

Three things. Foundations: a clean list, segments, emails that reach the inbox. Campaigns: the editorial calendar, newsletters, SMS, design and copy. Automations: welcome, abandoned cart, post-purchase, win-back. The goal: your customers come back.

Why Klaviyo rather than Shopify’s emails?

Shopify’s emails are enough to get started. Klaviyo goes further: segmentation, personalisation, and emails that look like your brand. That is what builds repeat purchases.

Can we work on a single area?

Yes. We take on one or several areas: paid media, eCommerce, CRM. We work with the agencies and freelancers you already have: we keep those who perform, and we tell you when they do not. We are simply more effective when we hold all three areas: each one feeds the other two.

How does a collaboration start?

With a first look at your figures, free of charge. A 30-minute call to get to know you and set up access, a few days of analysis, then a 30-minute debrief: a document you keep, and five actions for the next 30 days. No commitment. If you want to go further, the full audit takes weeks 1 and 2, and the launch happens in weeks 3 and 4.

How much does it cost?

Each offer is a fixed monthly fee, with no variable part. Attract, paid media: from €2,500 per month. Activate, eCommerce: from €3,350 per month. Retain, CRM: from €3,350 per month. The audit of the three areas: from €3,000, once.

What is the minimum commitment?

Three months, renewable by quarter, with 30 days’ notice. Three months is one full steering cycle: long enough to measure, short enough to correct.

How do you measure results?

With one scorecard shared by the three areas: acquisition cost, blended COS, conversion rate, average order value, repeat rate, LTV. A call every two weeks, a report every month. Every decision starts from your margin, not from the performance of a platform.

Which brands do you work for?

Fashion and lifestyle brands. Our goal: take your brand from €1M to €5M in eCommerce revenue, while staying profitable. We have supported 50 brands since 2024: you benefit from what we have learned with brands like yours.

Who works on our account?

Specialised senior consultants: there are 8 of them, with 7 years of experience on average, from brands such as Jérôme Dreyfuss, L:A Bruket, Printemps or Faguo. You meet the team that will work on your account before you sign.

What do we need to bring?

We accelerate what exists; we do not replace what is missing. You need a product range that keeps evolving, a steady flow of content, and real involvement on your side: quick decisions and trust. Acquisition, conversion and retention do part of the work. Product, brand and content do the rest.
