The problem

Manual signature updates are ignored or forgotten by users, leading to inconsistent branding and missed legal disclaimers. Bulk updating signatures one by one does not scale and quickly falls out of sync as new staff join or change details.

How it works

  1. Read the current user list from the directory.
  2. Generate each user's footer with up-to-date info (e.g. display name, role, phone).
  3. Set the signature for each account via the Gmail API, impersonating each user with the service account.
  4. Re-run regularly to catch new starters and changes.

What changes

All users have the correct footer, including new starters and changes, with no manual intervention required.

The trap in this one. If a user edits their signature after the delegated update, the Gmail API does not prevent overwrites on the next sync—so user changes silently vanish on the next run. This causes confusion and support tickets when staff try to personalise signatures and their edits disappear without warning.

Questions people ask

Can different departments have different footers?

Yes, generate the signature dynamically based on directory attributes such as department or location.

How often should the sync run?

At least daily to capture new starters and leavers, but more frequently if you require near real-time accuracy.

Want this built?

This is a pattern we run in production. We will set up the delegation and build this on top of it — $500 per hour, most of it working the same day.
