Directory sync

Directory sync ensures signatures automatically reflect current employee information. When someone gets promoted, their signature updates without manual intervention.

How It Works

  1. Signature tool connects to your directory (AD, Google, etc.)
  2. User attributes are mapped to signature fields
  3. Changes in directory automatically update signatures
  4. 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

Automatic directory sync

Siggly syncs with Google Workspace and Microsoft 365 directories to keep signatures current.
