Professional email signatures, built to survive the inbox.
This foundation centers the hard part first: a safe signature document model and a constrained renderer that outputs email-client-friendly HTML. The editor, media tools, and team workflows can grow on top of that without letting arbitrary HTML sabotage reliability.
Signature Foundation
Recommended Stack
Next.js, Fastify, Prisma/Postgres, S3-compatible asset storage, and a dedicated signature renderer.
Editor Strategy
Use drag-and-drop block composition, then render through a strict HTML pipeline instead of free-form WYSIWYG.
Asset Strategy
Crop and normalize images server-side so exports always use stable dimensions and predictable alignment.
Live Preview
The preview below is rendered from the shared package, not hand-authored HTML. That keeps web preview and API export aligned.
Professional Headshot
Rendered from the shared signature pipeline, not from ad hoc HTML.
