Lastline

What Lastline is

Lastline is a web service for managing branded email signatures across Google Workspace teams. Administrators can create signatures in a visual HTML editor, use professionally designed templates, and assign them by department, role, or organizational unit. Lastline imports employee details from Google Workspace Directory and updates signature information when directory records change. Administrators can then deploy signatures to Gmail across the organization with one click, without requiring employees to install anything.

Teams can schedule campaign banners and target them by team. The maker says Lastline tracks campaign clicks; Grow includes click tracking. The integration uses Gmail API, Directory API, and Admin SDK access. Lastline says it is SOC 2 Type II certified, encrypts data in transit and at rest, and does not read email content. Email support is included with every plan, while paid plans add priority support. Starter is free and includes three seats, 10 templates, basic analytics, and 10 AI signature generations per month. Grow costs $10 a month and includes up to 300 seats. Enterprise is for teams with 300 or more users and requires contacting sales for pricing.

Lastline suits Google Workspace administrators who want to manage employee signatures centrally and deploy them to Gmail without asking staff to install anything. Teams that need department-based templates or scheduled, targeted banner campaigns can use its assignment and campaign tools.
