Owned channel

Unlike social media, your email list is an asset you own. You're not at the mercy of algorithms.

Privacy shifts

After iOS 14+ and the death of third-party cookies, paid ads are more expensive and less precise. Email data is first-party.

AI personalisation

New tools enable hyper-personalisation at scale — something that used to require entire teams.

eCommerce growth

More and more DTC brands realise email is the core channel for repeat purchases and LTV.

05 — Process

Four stages, zero theatre.

01

Audit and strategy

We review your ESP, deliverability, segments and the last 90 days of sends. You get a written 30-page audit and a 12-week roadmap.

02

Building the foundation

We rebuild the flows that make money first — welcome, browse-abandon, cart, post-purchase, win-back. Always with our copywriting and design.

03

Campaign engine

Weekly campaigns mapped to your promotional calendar. Every send is segmented, A/B tested and checked against an internal revenue dashboard.

04

Compound and report

Monthly executive review. Quarterly strategy reset. We publish the wins in a shared Notion, so you always know what we sent and why.

07 — FAQ

Frequently asked questions

The objections we hear most often, answered honestly.

How long before we see results?

First flows go live in 2–3 weeks. Measurable revenue lift usually shows in month 2, and the full lifecycle program compounds over months 3–6.

Ask us directly

What exactly do I get for the monthly fee?

Strategy and segmentation, unlimited campaigns and flows, copy and design, A/B testing, deliverability monitoring, Slack support and a monthly revenue report. Setup is free; the email platform licence is not included.

Ask us directly

Why does it cost €500–€2,500 per month?

The fee is fixed, with no revenue share. For most stores one recovered cart flow already covers it — our clients average 37× ROAS on email.

Ask us directly

Do I have to switch email platforms?

No. We work in Klaviyo, Mailchimp, Brevo and The Marketer. If migration makes sense, we do it for you at no extra cost.

Ask us directly

Is there a lock-in contract?

No long-term lock-in. Monthly terms, 30 days notice, and you keep every flow, template and segment we build.

Ask us directly

How much of my team's time does it take?

About one 30-minute call per week plus async Slack. We handle strategy, copy, design, building and reporting.
