Bring centralized, compliant signature management to Microsoft Exchange environments — on-premises or hybrid — and any SMTP infrastructure, with server-side stamping that nobody can bypass.
Signatures are injected into messages in transit, before delivery. There's no way for a user to bypass the policy, and coverage extends to every device and mail client — including mobile.
If your organization sends through custom SMTP servers, Instant Signer can stamp professional, compliant signatures into those messages too — extending consistent branding beyond Microsoft and Google.
Target signatures with a powerful rules engine, append conditional disclaimers, and keep a complete audit trail of every change for compliance and peace of mind.
Join 2,500+ companies turning email signatures into their most consistent, on-brand, and measurable channel.
