Email signature management for Google Workspace.
One dashboard to create, assign, and deploy branded signatures across your team — synced from your directory, with zero per-employee setup.
Signatures are a mess. Lastline makes them a system.
Most companies have no idea what’s sitting at the bottom of their employees’ emails. Here’s the shift.
- Everyone formats their own signature, their own way
- Outdated titles, old logos, missing legal disclaimers
- Every rebrand means emailing all staff — and chasing them
- No one knows who actually has the right version
- One brand-approved design, locked across the company
- Names, titles & contacts pulled live from your directory
- Update once — it deploys to every inbox automatically
- A live dashboard shows exactly who’s covered
Three steps. Zero IT chaos.
From a messy mix of signatures to full, consistent coverage — without emailing every employee.
Connect your Workspace
Sign in as an admin and authorize once. Lastline syncs your directory automatically — no per-employee setup.
- One-time admin authorization
- Auto-imports every employee
- Scoped, minimal permissions
Design your signatures
Start from a brand-approved template or generate one with AI. Dynamic fields pull each person’s details on deploy.
- WYSIWYG + HTML editor
- Dynamic name, title, contact fields
- Lock the brand, once
Deploy to everyone
Assign by rule and push to Gmail in one click. Update a banner or detail and it rolls out to every inbox.
- Assign by department or role
- One-click deploy to Gmail
- Update once, applies everywhere
One place to run it all.
