Email signature management

On-brand email signatures on every message, from every device.

Exclaimer puts professional, consistent email signatures under central control — turning every email your team sends into a branding opportunity and closing a quiet compliance gap. Managed by Curatrix as part of your Microsoft 365 workspace.

What you need


What you need from email signatures — and how we deliver it

Signatures sound trivial until you look across a whole organisation: mismatched logos, missing disclaimers and broken formatting on mobile. Here's what businesses tell us they want — and exactly how Curatrix and Exclaimer answer each one.

The requirement

The same signature, everywhere

One consistent, professional sign-off whether staff write from a desktop, the web app, a Mac or a phone.

How we meet it: Exclaimer applies signatures in the cloud as mail flows through, so every message carries the right signature on any client or device — without relying on people to set anything up themselves.

The requirement

Disclaimers that are always there

Legal text and confidentiality notices that appear on every email — without anyone having to remember them.

How we meet it: Disclaimers are applied automatically to every outgoing message, with the wording tailored by department, region or recipient where you need it — closing a compliance gap most teams don't realise they have.

The requirement

Marketing space you actually use

A way to promote events, campaigns and news without designing a new email every time.

How we meet it: Add campaign banners directly into signatures and target them by sender, recipient or audience — so routine email becomes a measurable marketing channel your marketing team can run, not just IT.

The requirement

Rebrands done in minutes

When the logo, address or campaign changes, it should change everywhere at once — not desk by desk.

How we meet it: Update a brand element once in the central designer and the change rolls out instantly across every user and department — no scripts, no mail-flow rules and no chasing people to update Outlook.

The requirement

Details that stay accurate

Names, job titles and phone numbers that reflect reality as people join, move and change roles.

How we meet it: Signatures draw their details from Microsoft Entra ID and sync automatically, so contact information stays current without anyone editing templates by hand.

The requirement

Control without the bottleneck

IT keeps governance, but marketing and legal need to make safe changes without raising a ticket.

How we meet it: Role-based permissions let the right people edit content and design while IT retains overall control — collaboration without losing the single source of truth.
