The challenge
Professional email signatures are a daily brand touchpoint — yet most businesses rely on inconsistent manual HTML or outdated templates. Designbooth set out to build Mirosign (mirosign.com / app.mirosign.com): a subscription-based signature generator that combines design flexibility with team management, cloud image hosting, and one-click deployment to any email client.
The strategy
- Product design & UI/UX: An intuitive online editor with templates, typography, colour controls, social icons, logos, and banner elements.
- React / Gatsby development: Frontend application at app.mirosign.com with real-time signature preview and template selection.
- Backend architecture: Netlify Functions (TypeScript), Auth0 authentication, Stripe subscription billing, and Cloudinary image CDN.
- WordPress marketing site: Content-led mirosign.com driving discovery, documentation, and conversion to the product app.
The results
- A live SaaS platform serving individual professionals and team accounts.
- Subscription tiers with public/private image hosting tied to billing status.
- Inline HTML signature output compatible with major email clients.
