The average UK eCommerce brand leaves 25–35% of potential revenue untouched in its email list.

That's not a guess. That's what we find every time we audit a new client's Klaviyo account. The list is there. Thousands of contacts — people who've already bought or expressed interest. But the flows are stale. The campaigns are one-size-fits-all. Nobody's segmenting by behaviour. And the revenue attribution? Most brands can't even tell you what percentage of sales comes from email.

That's money left on the table every single day. While your ads get more expensive and organic takes months to build, email is sitting right there — your warmest audience, your cheapest channel, your highest-ROI marketing tool — and it's barely being used.

GOSH Digital fixes that. As a Klaviyo Gold Partner, we've built email and SMS programmes for 150+ brands. We audit what's broken, rebuild flows from scratch, segment your list by actual buying behaviour, and turn your email channel into the profit centre it should be. Birmingham's eCommerce brands are growing fast. With GDPR making third-party data harder to leverage, your owned email list is more valuable than ever. We help you extract every pound from it.
