Directory sync ensures signatures automatically reflect current employee information. When someone gets promoted, their signature updates without manual intervention.
How It Works
- Signature tool connects to your directory (AD, Google, etc.)
- User attributes are mapped to signature fields
- Changes in directory automatically update signatures
- Signatures deploy to email clients
Common Directory Attributes
- Display name
- Job title
- Department
- Phone numbers (office, mobile)
- Office location
- Manager
- Custom attributes
Benefits
- Accuracy — Single source of truth
- Automation — No manual updates needed
- Consistency — Everyone's info stays current
- Reduced IT work — Fewer signature support tickets
Best Practices
- Keep directory data clean and complete
- Standardize job titles and departments
- Include directory updates in HR processes
- Test sync before broad deployment
