OneTimeProfessional email signatures for your whole team — on your desktop, forever.
WiseStamp charges $6/month per user, forever, to generate what is at the end of the day a block of HTML — and the free tier stamps their ad into your signature. SigCraft does the same job locally, for every team member you'll ever have, with zero recurring cost and zero telemetry.

Fair questions
Is it really free on GitHub?
Yes — MIT source at github.com/bensblueprints/email-signature-mvp. $15 buys the signed Windows installer, 1-click setup and updates.
Will the signature render correctly in Outlook?
Yes — output uses table layouts, fully inline styles and VML conditional comments for the CTA button, the techniques email developers use for Outlook compatibility.
Can I make signatures for my whole team?
Yes — team mode imports a CSV and batch-exports a folder of .html signatures with your chosen template. No per-user pricing, ever.
Does it have as many templates as WiseStamp?
No — 10 versus roughly 50. We'd rather ship 10 templates that render everywhere than 50 that break in Outlook. If you want maximum variety, WiseStamp wins there.
Does it phone home or inject branding?
Never. No network calls, no telemetry, and nothing of ours in your signature — unlike WiseStamp's free tier, which stamps its ad into every email you send.
