Features
What it does for you.
Everything you need so that everyone in your organization sends the right signature, without thinking about it.
Applied automatically
Inserted while composing and confirmed on send, without a single action from the user.
Microsoft 365 group targeting
Every department gets its own signature. Priorities decide which one applies.
Your data, in real time

Logos, tables, colors and HTML. A preview rendered with real user data.
And on mobile too

Four steps, then it runs itself.
From sign-in to the first signed email, with no heavy IT project.
