Every employee's email signature is a tiny brand impression — and at most companies, it's a complete mess: outdated titles, broken logos, different fonts per person. SyncSignature centralizes it: one dashboard pushes a branded signature to every employee's Gmail or Outlook automatically, no copy-paste required.
SyncSignature is infrastructure, not a design tool — the design part (templates, branding) is simple. The actual product is the automated deployment that keeps signatures correct without anyone touching them after setup.
OAuth-based admin consent — SyncSignature gets read access to the employee directory (names, titles, departments) via the Admin SDK or Microsoft Graph API.
Drag-and-drop editor, or paste in existing signature HTML. Logo, colors, layout — set once for the whole company.
Name, title, phone, department pull straight from the directory — no manual data entry per employee.
Gmail via the sendAs API, Outlook via a Centralized Deployment add-in — employees see it appear with zero action required on their end.
India's IT/services and startup sector is full of fast-growing companies hiring 10-50 people a quarter — exactly the growth stage where signature chaos sets in and nobody owns fixing it.
Scoped to Google Workspace only (skip Microsoft 365 integration for v1 — it roughly doubles the OAuth/API complexity). A working, single-tenant version is realistic by Sunday night.
Template editor, employee list, and settings — the whole admin-facing app in one framework.
Stores company accounts, templates, and synced employee directory data.
Reads the employee directory and writes signatures directly into each user's Gmail sendAs settings.
Per-seat monthly billing — works cleanly with a 5-seat minimum subscription model.
Uploaded logos need to be hosted on a fast CDN so signature images load reliably across email clients.
Fast enough to build both the admin dashboard and the signature template editor in a weekend.
Honest heads up: using the Gmail/Admin SDK APIs at production scale requires a Google OAuth verification review (a few days to a couple weeks) once you exceed limited testing use — same pattern as the SheetAI guide. Weekend goal: fully working for your own company and a couple of design-partner companies before public OAuth verification.
