Directory sync
Email signatures powered by your Google Workspace directory
Stop asking people to type their own details. SigDeploy reads your Google Workspace user directory, so every signature carries the right name, title and phone number.
Last updated October 8, 2026
Connect once with a guided setup
A Google Workspace super admin adds SigDeploy through domain-wide delegation in the Admin console. A step-by-step walkthrough shows every click, and SigDeploy verifies the connection against the Directory API for you.
Google can take a little while to apply delegation changes, so the setup tells you when it is verified instead of leaving you guessing.
admin.directory.user.readonly
Read-only access to your user directory: names, titles, phones, org units and photos.
gmail.settings.basic
Permission to update Gmail signature settings. SigDeploy does not read or send email.
Your whole team in one grid
Fetch the directory and see everyone who needs a signature, with filters, search and photos. It is the quickest way to spot who is missing a title or phone number before a deployment.
Fix a detail once and it stays fixed
If a job title or phone number in Google is out of date, correct it in the employee grid. Your correction is stored separately from the directory, so refreshing the directory never overwrites it.
New hires
When someone joins, fetch the latest directory from Google and deploy to the new person in one click. Fully automatic new-hire deployment is on the roadmap and is not part of the product today.
Frequently asked questions
What access does SigDeploy need?
Two Google permissions, added once through domain-wide delegation: read-only access to your user directory, and permission to update Gmail signature settings. SigDeploy does not read anyone's email.
Who can set it up?
A Google Workspace super admin. The guided setup walks through each step and verifies the connection automatically.
What if a title or phone number in Google is wrong?
Correct it in the employee grid. Your fix is stored separately, so refreshing the directory never overwrites it.
Can I take access back?
Yes. Remove the delegation in your Google Admin console and SigDeploy's access ends immediately.
