Read articleMetal Jelly is a specialist consultancy for email marketing, marketing automation, and marketing operations. Senior expertise across B2B and B2C — from strategy to inbox placement.
Pick the scenario that sounds most like you.
You have a pipeline problem and email isn't pulling its weight.
You're leaving revenue on the table and you know it.
Something's gone wrong and you need someone who actually knows email.
About
Metal Jelly is a two-person consultancy with 15+ years of combined experience in email marketing, CRM, and marketing operations. We've worked across both sides of the industry — client-side at fintech, B2B SaaS and e-commerce companies, and on the platform side at ESPs.
That breadth matters. We understand how inboxes actually work, not just how platforms claim they do. We know how to build programmes that perform — and how to fix ones that don't.
We work directly with you. No account managers, no juniors. You get senior practitioners from day one, whether it's a one-off audit or a long-term retainer.
Based in the UK. Working with clients globally.

What we do
End-to-end email and marketing operations expertise — from channel strategy and automation to infrastructure and inbox placement.
We build programmes that drive results — from channel strategy and audience segmentation through to creative direction, copy, and rigorous A/B testing.
We design and build automated programmes that engage the right people at the right moment — lead nurture flows, onboarding sequences, re-engagement, and multi-touch journeys.
Inbox placement is infrastructure, not an afterthought. With platform-side experience from inside an ESP, we understand deliverability at a technical depth most consultants don't reach.
The plumbing behind great marketing matters. We audit your stack, run ESP selection and RFP processes, manage migrations, and fix the data problems that quietly undermine your programmes.
How we work
We fit around how you work — whether that's a defined project, an ongoing retainer, or a targeted piece of consultancy.
