Flows + segments
Email marketing is unique among marketing channels because you own the audience. Your email list is not subject to Meta's algorithm changes, Google's SERP redesigns or TikTok's policy shifts. Once someone subscribes, you can reach them in their inbox indefinitely, at zero per-message cost beyond your ESP subscription.

We work with UK ecommerce brands (Klaviyo), SaaS companies (HubSpot, Customer.io), professional services (Mailchimp, ActiveCampaign) and content publishers (ConvertKit, Substack).

Industry-dependent. UK ecommerce: 35-45% open rate, 2-4% click rate. UK B2B: 25-35% open rate, 3-5% click rate. Lifestyle/content: 40-55% open rate. Apple Mail Privacy Protection inflates open rates artificially, we focus on click rate and revenue per recipient as more reliable metrics.
We write and design every email. You approve before send. This is included in the retainer, no per-email fees. Most clients find this faster (no production bottleneck on their end) and higher quality (we're emailing for a living).
Send us your ESP access. We'll audit your campaign performance, flow architecture, deliverability and list quality, then send a written report with the 5 highest-impact opportunities.
