FAQ

Questions, answered.

Lastline requires access to the Gmail™ API (for signature deployment), Directory API (for employee sync), and Admin SDK (for organization-wide management). We follow the principle of least privilege and only request the permissions we need.
Yes, you need Super Admin or delegated admin privileges to authorize Lastline to deploy signatures across your organization. Individual users can also create signatures for themselves without admin access.
Once connected, employee import takes seconds. Signature deployment to Gmail™ happens instantly — your team will see their new signatures on their next email.
That's up to you! You can lock signatures for full brand control, or allow employees to customize certain fields (like personal phone numbers) while maintaining brand guidelines.
Your employees keep their existing signatures — nothing is deleted. Lastline's OAuth tokens are revoked and we no longer have access to your Google Workspace™. You can reconnect anytime.
