Frequently Asked Questions

How do I deploy Gmail™ signatures to my entire organization?
Connect Lastline to your Google Workspace™ via OAuth. Create your signature templates in our editor, then use assignment rules to deploy to specific users, organizational units, or groups. Click deploy and signatures are applied instantly.
What Google Workspace™ permissions does Lastline need?
Lastline requires Gmail™ Settings API access to update signatures. We use the minimum required scopes and never access email content. All authentication uses secure OAuth 2.0.
How does employee sync work?
Lastline connects to your Google Workspace™ Directory API to automatically import employees. New hires get signatures automatically, and departed employees are removed. Sync happens in real-time or on a schedule you choose.
Can I target signatures by department or office?
Yes! Use Google Workspace™ organizational units (OUs) or groups to target signatures. Create different templates for Sales, Support, Legal, etc. and assign them automatically based on OU membership.
Do I need to be a Google Workspace™ super admin?
You need admin access to authorize the initial connection, but day-to-day signature management can be delegated to other team members with limited permissions.
