Lastline is an email signature management platform built for Google Workspace. An administrator creates, assigns, and deploys branded signatures to every employee's Gmail account from one dashboard. Names, titles, and contact details come from the company directory, so staff do not need to build or maintain their own signatures.
It targets a familiar problem: signatures with outdated titles, old logos, and missing legal disclaimers. Lastline places every signature under one admin and shows who is covered. It offers a free Starter plan and a $10 per month Grow plan, and states that it holds SOC 2 Type II certification.
Setup has three steps. A Google Workspace Super Admin signs in and authorizes Lastline once, using Domain-Wide Delegation, and Lastline imports the directory. Employees are not asked to configure anything or install software, since signatures are deployed directly to Gmail.
Next, the admin starts from a template or generates one with AI in a WYSIWYG or HTML editor, using dynamic fields for name, title, and contacts. Signatures are then assigned by department or role and pushed in one click. With directory sync on, new hires are picked up automatically and departed employees are removed.
The editor supports rich formatting and custom HTML, with templates and AI generation as starting points. Assignment rules cover departments, roles, and Google Workspace organizational units, which helps multi-location or multi-brand organizations. A dashboard shows coverage by department, a setup checklist, and employees needing review, while an audit trail logs every change and can be exported.
Marketing features sit mostly on the Grow plan. Teams can build banners in Canva, set go-live and expiry dates, target specific teams or offices, and track opens and clicks per campaign. Grow also adds disclaimer management and advanced analytics, plus priority support. The integration page lists analytics and tracking as coming soon, so confirm availability.
