Email Template Development in London
Building email templates for London organisations that survive the clients people actually use. Email is not the web — several major clients render with a decades-old engine, dark mode inverts colours you chose deliberately, and a layout that looks correct in the preview can arrive as a stack of broken images.
Why this comes up
The problem
The template renders beautifully in the builder and collapses into a single column of alt text in Outlook.
What you get
What we deliver
- Built with the techniques that work across clients, including the older engines
- Dark mode handled deliberately rather than left to be inverted unpredictably
- Tested on real clients and devices, not only in the platform's preview
- Images treated as enhancement, since many recipients see them blocked by default
- Accessibility addressed — reading order, alternative text, contrast, real text
- Modular sections built so the marketing team can assemble campaigns unaided

Working in London
London
London clients usually come to us because they want senior people actually on their project rather than a large agency's B team, and because Midlands rates buy considerably more delivery per pound.
Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates.

Email Template Development in London — common questions
- Why is Outlook still a problem?
- Because desktop versions render with an engine borrowed from a word processor. Modern layout techniques are unsupported, spacing behaves differently and background images frequently vanish — which is why email is still built with table structures a web developer abandoned years ago.
- What happens in dark mode?
- Clients invert colours according to their own rules, and inconsistently. A white logo on a light background disappears, carefully chosen brand colours shift, and text becomes unreadable — so the sensible approach is designing for both rather than discovering the result after sending.
- Should the design depend on images?
- Never entirely. Many clients block images until the recipient chooses to load them, so an email whose message lives inside a graphic arrives as empty space — the text has to carry the message with images improving it rather than delivering it.
- Why build modular sections?
- So marketing can send without a developer. A set of tested blocks that can be reordered and reused means campaigns go out on time and still render correctly, whereas a bespoke build per send makes every campaign dependent on someone who knows the quirks.
- Do you work with businesses across Greater London?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout London, including London and the surrounding Greater London area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of London businesses do you usually work with?
- Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates. Beyond that we work across Financial Services, Professional Services, Technology, Media, Hospitality and Retail.
- Do you cover the areas around London?
- Yes — we work throughout London, including Reading, Milton Keynes, Cambridge, Brighton. London is an urban area of roughly 9,000,000+, and we take on work across the wider Greater London region rather than the city boundary alone.
