Inkwell — An Email Platform for Creators
A live inbox in perspective, where campaigns type their own subject lines and send themselves while open rates count up.
A dark email-marketing SaaS site drawn entirely in code. A live inbox in perspective types and sends its own campaigns under a drifting crimson-violet aurora; then an editor that assembles an email as you scroll, an automation flow with moving dots, deliverability stats, a template gallery, and pricing that recalculates from a subscriber slider. It is one self-contained HTML file — inline CSS and JavaScript, no framework and no build step — with every visual drawn in code. Under the hood: Vanilla JS, live animated inbox mockup in HTML/CSS, scroll-assembled drag-and-drop editor, SVG automation flow with travelling dots, crimson/violet aurora glow with pointer drift. What a visitor can do: watch campaigns type and send themselves in the hero, scroll to drag blocks into the email editor, slide a subscriber count to recalculate pricing live, hover templates to scroll their previews. Best for: Email & newsletter platforms, Creator-economy SaaS, Marketing automation tools, Small-business software.

Questions about Inkwell
Who is Inkwell for?
Inkwell is for SaaS and email products, and for the designers, developers and agencies who build their sites. It's a foundation rather than a site for one business: ask your AI to make it about yours and it rewrites the copy, colours and images around the same build.
What is Inkwell built with?
Inkwell is built with HTML/CSS/JS. The source is a single HTML file: open it in a browser and it runs, with no build step. The prompt is written for coding agents such as Claude Code, Cursor and Antigravity.
Can I use Inkwell for a client project?
Yes. Every purchase includes a commercial licence: use it in your own projects and in work you deliver to clients, including paid client work, change and rebrand it, and publish the result with no credit needed. What you can't do is resell, share or republish the prompt or the source files themselves.
Should I buy the prompt or the source?
The prompt is the written brief that built the design: paste it into a coding agent such as Claude Code, Cursor or Antigravity and it builds the site on your computer, which you then refine. The source is the finished project itself, ready to run exactly as the preview shows. The source always includes the prompt.
Will the prompt give me exactly the preview?
Not exactly, and that's expected. A prompt is a starting point: AI output varies between tools and between runs, so plan to refine spacing, timing and copy. The source pack is the preview itself, finished and running.
Can I get a refund?
Single designs are final once delivered, unless something is wrong on our side: a broken or empty download, a pack that isn't what its page describes, or a double charge. Then email support@brandmotion.in with your receipt and we fix it or refund it. The full terms are on the refunds page.
