Email Signature Software | SyncSignature

Deploy & manage email signatures across your Microsoft 365 organization with Entra ID directory sync
SyncSignature is email signature management software for Microsoft 365 teams. It connects to Entra ID (Azure Active Directory), reads employee data, and deploys branded signatures to every user's Outlook through a lightweight add-in.
Architecture:
SyncSignature uses two components for Microsoft 365:
Microsoft Graph API reads employee data from Entra ID with read-only permissions (User.Read.All, Group.Read.All, Directory.Read.All). SyncSignature never writes to your directory.
A lightweight Outlook add-in deployed through Microsoft 365 Centralized Deployment renders signatures in Outlook Web, Outlook Desktop, and Outlook Mobile. Deployment is admin-controlled with no end-user action required.
Both components work together: the Graph API provides the employee data, the add-in applies the signature. No mail flow rules, no transport rules, no MX record changes.
Key capabilities:
Entra ID / Azure AD directory sync pulls employee names, titles, departments, and custom extension attributes (extensionAttribute1-15) into signature templates automatically
Group-based template targeting using Entra ID security groups and distribution lists
Centralized signature deployment with no end-user installation steps
Banner campaigns with scheduling, group targeting, and click tracking
Built-in analytics for link clicks and campaign performance
Multi-workspace management for agencies and MSPs
Conditional field visibility hides empty directory fields automatically
Privacy and security:
SyncSignature applies signatures client-side through the Outlook add-in. Emails are never routed through SyncSignature servers. Directory access is read-only. Authentication uses standard OAuth 2.0 with admin consent.
Pricing:
$2/user/month (annual billing), 5-seat minimum. All features included on one plan: directory sync, templates, banners, analytics. Volume pricing scales to $1.40/user/month at 100+ users. 7-day free trial, no credit card required.
Getting started:
An admin grants Graph API consent, deploys the Outlook add-in via Centralized Deployment, and configures signature templates in the SyncSignature dashboard. Total setup time: approximately 30 minutes for a full organization.
