Directory Sync
Connect Employee Data. Generate Branded Signatures. Deploy Them Everywhere.
Email signature management system is built for organizations that want to manage employee email signatures centrally, professionally, and at scale.
Instead of relying on every employee to create, update, or copy their own email signature, system connects to your existing employee data sources, creates personalized branded signatures, and deploys them across the email tools your company already uses. AdSigner can support a fully automated enterprise setup, a partially integrated workflow, or a simple manual process for smaller teams.
From Microsoft 365 and Google Workspace to Outlook, Gmail, Thunderbird, standalone email clients, HTML signatures, and custom API-based workflows, AdSigner gives your organization full control over one of the most visible brand touchpoints in daily business communication: employee email.

Directory Sync
Directory sync is automatic periodic synchronization and is the recommended option for organizations that want employee signatures to stay up to date with minimal manual work.
AdSigner periodically connects to your selected data source and updates employee information inside the platform.
This means that when something changes in your organization, such as an employee’s job title, phone number, department, or office location, AdSigner can use the updated information to refresh the related email signature.
Automatic synchronization helps reduce manual errors, saves time for administrators, and keeps all signatures consistent across the company.
Flexible Data Sources With Priority-Based Merging
AdSigner lets your organization collect employee data from multiple sources and combine it into one reliable employee profile.
You are not limited to a single system or workflow. Data can be pulled from different sources and structured into a consistent format. This unified profile is then used to generate accurate, up to date and branded email signatures.

Supported Automatic Sync Sources
AdSigner supports synchronization with commonly used business directories and data systems.
Microsoft 365, Microsoft Entra ID
formerly known as Azure Active Directory
AdSigner can connect and sync with Microsoft Entra ID to collect employee information and prepare signatures for users in your Microsoft environment.
This is ideal for organizations that already manage users, email accounts, and collaboration tools through Microsoft 365.
Google Workspace, Google Directory
AdSigner can connect with Google Workspace to collect user data and prepare signatures for Gmail and other Google-based environments.
This is ideal for organizations that use Google Workspace as their main communication and productivity platform.
JSON Endpoint
For companies that store employee information in internal systems, HR platforms, CRM systems, or custom databases, AdSigner can collect data from a JSON endpoint.
This option gives organizations a flexible way to connect custom data sources without relying only on Microsoft or Google directories.
Custom Data Sources - API
This allows your technical team to connect AdSigner with internal tools, employee databases, HR systems, identity platforms, HR software, CRM systems, or other business platforms.
Our support team can assist you throughout the integration process. We can advise your technical team, help define the best integration approach, or develop custom integration tools based on your needs.
