Email signature management · Microsoft 365 & Google Workspace
UnifySig applies branded, compliant signatures across Microsoft 365 and Google Workspace from one console. Connect the tenant, design once, assign by group. Staff never touch it, and it looks the same on the phone as it does in Outlook.
UnifySig is in private preview ahead of full launch. Want to see it sooner? Book a 20-minute demo.

Why this keeps coming back
Every IT team has tried the PDF, the Outlook template, the transport rule. Here is what actually goes wrong, and what UnifySig does about it.
Twelve fonts, four logos, two people still listing the fax number. Marketing sends a PDF of the "new" signature and about a third of staff paste it in.
UnifySig writes the signature server-side as mail leaves the tenant. Nobody pastes anything, and the old ones stop mattering.
Outlook for Windows is fine. Outlook on iPhone, the Gmail app, a shared mailbox on a kiosk: each one drops the signature or mangles the HTML.
Because the signature is applied in transit, every client gets the same result, including mobile, web, shared mailboxes and mail sent from line-of-business apps.
Someone changes title, moves office or leaves. The directory is right within the hour; their signature says otherwise for months.
Fields come from Entra ID or Google Directory on every send. Fix the directory once and the signature is correct on the next email.
A transport rule appends it, then it appears three times in a thread, or not at all for external replies from a phone.
Disclaimers are part of the signature policy: once per thread, only where you say, with a version history when legal changes the wording again.
How it works
Four steps, none of which involve touching an endpoint or emailing instructions to staff.
Sign in as a Global Admin (M365) or Super Admin (Google) and approve a short list of read-only scopes. Nothing is installed on endpoints.
Start from a template or paste your existing HTML. Drop in directory fields, a banner slot and a disclaimer. Preview against real users.
Map signatures to security groups, dynamic groups or organisational units. Order rules, set exceptions, see who gets what before you turn it on.
Directory changes flow through automatically. Marketing schedules banners without a ticket. You get an audit log and a monthly summary.
Platforms
Plenty of organisations run Google for some teams and Microsoft for others, or are mid-migration. UnifySig treats each as a connected tenant under one policy set.
From IT teams
What admins tell us after the first month.
“We had signatures on the backlog for two years. It took an afternoon. The bit I did not expect was how little I have thought about it since.”
“Marketing can schedule a banner for a campaign without raising a ticket with us. That alone paid for it.”
“Read-only Graph scopes and no mailbox content stored. Our security review took a week instead of a quarter.”
Leave your work email and we will send one message when the service is fully live, with early-access pricing for the first cohort.
