What the audit gives you
A score per area, a ranked fix list and the proposal for a system. The example alongside is what a typical multi-property programme looks like before any work starts: campaigns in good shape, the transactional and automated emails nobody has looked at in years.

What a system is made of
- Tokens
- Colour, type, spacing and radius per brand or property. One file, no hex codes in templates.
- Components
- Header, hero, story, product pair, grid, voucher, CTA, footer and more. Hand-coded, tested in Outlook, Gmail, Apple Mail and dark mode.
- Journeys
- Welcome, booking and order confirmation, pre-arrival or dispatch, campaign, loyalty and win-back, assembled from the components.
- ESP build
- Delivered into your platform with locked structure and editable content regions, so the team cannot break what they did not build.
- Documentation
- What each block is for, what can change, how to add a property. The thing your next hire reads on day one.
By sector
Questions buyers ask
Which email platforms do you build for?
Dynamics 365 Customer Insights, Salesforce Marketing Cloud, Braze, Klaviyo and HubSpot. Other platforms are usually fine; the component library is plain HTML, so the ESP work is an adapter layer.
Who owns the system once it is built?
You hold a perpetual licence to use and modify everything delivered for your brand. The underlying framework stays with Inbox Innovation so it can keep improving across clients.
We already have an agency. How does this fit?
Well. Agencies build campaigns; the system gives them rails. Most engagements include a review of agency-built templates, and System Care exists partly to keep agency work inside the system.
How much of our time does it take?
Two or three working sessions for the audit, four to six for a system build, and a handover session at the end. Everything else runs asynchronously.
Can our marketing team really build emails themselves afterwards?
Yes, within the structure. They choose blocks, change content and images, and send. They cannot change layout, type or colour, which is the point.
Do you work outside the UK?
Yes. The work is remote and clients to date have included properties in London, Los Angeles and the French Riviera.
