We believe every email an organization sends should be perfectly branded, compliant, and working harder — without anyone copying and pasting HTML. That belief is why we built Instant Signer.

Instant Signer started with a simple frustration: managing email signatures across a growing company was needlessly painful.
IT teams were stuck maintaining brittle scripts and transport rules. Marketing couldn't keep branding consistent or measure the impact of the millions of emails their colleagues sent every month. And the enterprise tools that solved it were expensive and complex.
We set out to build a platform that's powerful enough for enterprise governance, simple enough to deploy in an afternoon, and priced so any team can afford it. Today, Instant Signer manages branded, compliant signatures across Microsoft 365, Google Workspace, and Exchange for thousands of organizations.
Powerful software should be easy to deploy. We obsess over removing steps, scripts, and surprises so you can be live in an afternoon.
We treat your directory data and email with the highest care — privacy by design, least-privilege access, and never storing your message content.
Every core feature is included at every tier. Transparent, per-account pricing with no upsells and no enterprise gatekeeping.
We build what teams actually need and support them like partners. Your feedback shapes our roadmap.
