The problem
Legal Risk Hides in Every
Email Without the Right
Disclaimer
Without centralized control, a single non-compliant email
from any lawyer, paralegal, or staff member can expose your firm to
serious liability.
Disclaimers missing on mobile and for new starters
Manual signature setups mean lawyers on mobile devices or new starters often send emails with no disclaimer at all, a compliance failure waiting to happen.
Wording that goes stale
After an office move, merger or rebrand, old disclaimer wording and addresses can stay in use because each person maintains their own signature.
No record of what was sent
Without central control it is hard to show which signature and disclaimer went out with an email. The optional Signature in Sent Items setting and the Activity Log support record-keeping.

Complete
Control
Sigsync provides centralized governance for email signatures, helping organizations mitigate compliance risks, enforce legal disclaimers, and maintain consistent branding across all communications.

Core Capabilities
Built for Legal Compliance,
Not Just Aesthetics
Automated Legal Disclaimers
Append jurisdiction-specific disclaimers to every outbound email automatically including emails sent from mobile devices, Outlook, and OWA. No user action needed.
Centralized Dashboard Control
Manage signatures and disclaimers for your entire firm from a single web-based portal. Update the template once and the change applies to everyone covered by the rule.
Microsoft Entra ID / Microsoft 365 Integration
Sigsync pulls each user's details name, title, direct dial, office — directly from your Active Directory. Signatures stay accurate without any manual data entry.
Rule-Based Signature Assignment
Assign different signature templates and disclaimer text to different departments, offices, or seniority levels. Each practice group gets exactly the right signature.
All Devices, All Email Clients
Server-side signature injection means compliant disclaimers are applied after every email is sent — regardless of whether the sender is on desktop, tablet, or mobile.
Sent Items Compliance Record
Optionally include the full signature in Sent Items, giving you a complete and accurate audit trail of every email sent — critical for legal record-keeping.
Attorney details
What a Law Firm Email Signature
Should Include
Use a consistent template for the details your firm chooses to publish. Microsoft 365 user properties and configured custom fields can supply attorney-specific information.
Contact and branding
Direct dial, mobile number and the correct office address, together with your firm’s logo and approved branding.
Approved notices
Confidentiality and privilege wording, and any attorney advertising notice your firm determines is required.
Your firm remains responsible for approving disclaimer wording and deciding which information to include for each jurisdiction.
Powerful Features & Advanced Capabilities
Go beyond simple text formatting. Sigsync offers
enterprise-grade functionality to automate
the most complex signature
requirements smoothly.
Dynamic Active Directory Sync
Integrates deeply with Microsoft Entra ID (Azure AD). When a lawyer is promoted, their signature title updates after the next directory synchronization, without manual intervention.
Targeted Marketing Banners
Run different banners for different practice groups. Promote the M&A webinar below the M&A team’s signatures, and the new Chambers ranking below the Litigation team’s. See email signature marketing for scheduling and tracking.
Granular Role-based Access
Give the marketing team access to update promotional banners while restricting them from modifying structural disclaimer policies assigned to IT or Risk Management.
Group-based templates
Use different signature templates and disclaimers for different practice groups and offices, based on the sender's Microsoft 365 group.
Recipient rules
Separate Disclaimers for Clients and Colleagues
Use a full firm-approved notice for external correspondence and a shorter version for internal messages where appropriate.
Sigsync recipient rules distinguish internal and external recipients and can target specific domains or addresses.
Central control
Keep Server-Side
Disclaimers Under Admin Control
Manage signature templates centrally and apply them after sending. Ordinary senders do not edit the server-added disclaimer in their composing window.
Only account owners and authorized admins can change templates or rules. The Activity Log records administrative actions for review.
Security review
Security for Your
Risk and IT Teams to Review
