Demo

From the console to Outlook, in one take.

Create a signature, target a group, and watch it land in Outlook.

Demo: in the ATOM console, an admin creates a signature, inserts the {Full name} and {Title} tokens into the signature card, targets it to the Microsoft 365 group “Sales”, then opens Outlook where the signature is inserted automatically into a new message.

Features

What it does for you.

Everything you need so that everyone in your organization sends the right signature, without thinking about it.

Deployed once, for the whole organization

A single admin consent is all it takes. No sideloading, no per-user install. The signature lands in Outlook on Windows, on the web and on Mac.

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

Fields populate straight from Microsoft Graph, including up to 15 extension attributes.

Full visual editor

Logos, tables, colors and HTML. A preview rendered with real user data.

And on mobile too

The same add-in applies the signature in Outlook on iPhone and Android — new messages, replies and forwards. Nothing for employees to do. No one gets left out.

Four steps, then it runs itself.

From sign-in to the first signed email, with no heavy IT project.
