Signstamp is a free email signature generator that actually saves your work — something HubSpot's popular tool doesn't do. Build a signature in minutes, no login, no watermark. When you're ready to standardize across a team, upgrade to a paid plan: build one on-brand template, push personalized install links to everyone at once, and skip the back-and-forth with IT. Works with Gmail, Outlook, Apple Mail, and Zoho — no Google Workspace admin access required.

Hey Product Hunt 👋

Signstamp started as a two-day build: a genuinely free email signature generator that doesn't lose your work when you close the tab. It's grown into a small suite signatures + a digital business card with QR/tap-to-share, both free to start.

Free is free forever (3 saved signatures, 16 templates, small "Created with Signstamp" credit). Pro removes that branding, gives you unlimited signatures, and turns your business card into a contact-capture tool with view analytics.

For launch day only: first 100 people get lifetime Pro for $49, one-time, no subscription. [X/100 spots claimed] grabbing one is honestly the best way to support the launch.

Would love feedback, especially on what you'd want from Gmail auto-sync (it's next on the roadmap). Reading every comment today 🙏
