Signatoro

About the startup

Signatoro gives AI agents and automation workflows a way to append a real, up-to-date email signature to every outgoing message. Each user gets a personal API key, and any AI assistant, CRM, n8n, Zapier, or Make scenario can call the REST API to fetch the saved signature at send time. No mail-server configuration is involved: there are no server-side rules, no Group Policy scripts, and no add-ins to install. The API also supports a "short" cold-outreach mode that returns only a name, role, and one link, alongside the full signature mode for standard correspondence. For humans building signatures by hand, Signatoro offers five layouts, one accent colour, and an optional photo or logo upload. A signature can be created in minutes and pasted into Gmail, Outlook (classic and new), Apple Mail, Zoho Mail, iOS Mail, or any client that accepts HTML. Zoho Mail is supported natively, so teams already inside the Zoho ecosystem can adopt Signatoro without workarounds. Export options include copy as plain text, copy as HTML, download, and a test-email send. Paid plans add PNG export for tools that require an image-format signature. Company branding is controlled in one place. An owner sets a single logo, accent colour, and font, and those choices propagate to every team member's signature automatically. When the owner updates the brand, each person receives their new signature by email. Team members are invited by email and keep their own name, title, phone number, links, and photo.…
