The email marketing agency that turns your list into predictable revenue
Most brands sit on a list worth six figures and send three campaigns a year. We build the flows, the segments and the calendar — then run them weekly, with revenue per email reported every month.
What you gain working with Horizon
Flows before campaigns
Welcome, abandoned cart, browse abandonment, post-purchase, winback and replenishment. Automated flows typically drive 30–40% of email revenue while you sleep — we build them first, then layer the campaign calendar on top.
Deliverability engineering, not guesswork
SPF, DKIM, DMARC, domain warm-up, list hygiene and engagement-based sending. An email marketing agency that ignores inbox placement is just writing copy nobody reads.
Segmentation that respects the reader
Behaviour, purchase history, lifecycle stage and predicted value drive who gets what. Fewer, sharper sends beat daily blasts — and they keep your unsubscribe rate low.
Reported in revenue, not opens
Every month you get attributed revenue per flow and per campaign, list growth, and the cost per euro earned. Open rate is a diagnostic, not the goal.

What does an email marketing agency actually do?
We own the whole channel: strategy, segmentation, automated lifecycle flows, the campaign calendar, copywriting, design, deliverability and reporting. You approve the plan; we build, send, test and report on revenue every month.
How much does email marketing management cost?
Retainers typically start around €748/month for campaign management and scale with send volume and flow complexity. Initial flow builds are quoted separately as a one-off. You get a fixed monthly fee after the audit — no hourly billing.
Which email platforms do you work with?
Klaviyo, Mailchimp, Brevo, Customer.io, HubSpot and Shopify Email, plus custom sending on Resend or Amazon SES when volume justifies it. We recommend the platform in the audit if you haven't picked one.
How fast will I see results?
Core flows go live in 3–4 weeks and start producing revenue immediately since they trigger on existing traffic. Campaign performance compounds over the first 60–90 days as segmentation and testing data build up.
My list is old and cold — is it worth it?
Usually yes. We run a re-engagement sequence and sunset the truly dead addresses, which both recovers revenue and repairs your sender reputation. A cleaner smaller list almost always outperforms a large unengaged one.
