01 — The story
Stop “Sent from my iPhone”.
Open any company’s sent folder and you will find the signature graveyard: last year’s logo, a rogue font, a phone number nobody answers and, under half of them, “Sent from my iPhone”.
fixSignatures lets IT set the signature once and deploy it to every Microsoft 365 mailbox. It syncs names, titles and numbers from Entra ID and renders the same in Outlook on the desktop, on the web and on mobile. It never reads anyone’s email to do it.
Designed for IT. Loved by Marketing.
02 — The idea
An envelope that signs itself.
The mark tells the whole story in one line: an envelope whose flap turns into a tick, with a signature running underneath.
Around it everything is calm and familiar, signature blue on cool greys with Inter for every word, because the people who buy it live inside Microsoft 365 all day and want a tool that feels like it belongs there.

03 — Building it
Built for the person who rolls it out.
The buyer is an IT admin with forty other things to do, so the app is built around getting a whole organisation right in one sitting.
It starts as a checklist.
Connect Microsoft 365, create a signature, deploy the add-in, and watch the sync status turn green.
The editor shows the real thing.
HTML and a live preview side by side, rendered for any actual person in the organisation, not a placeholder.
One template for everyone.
Variables handle what changes from person to person, like taglines and links, so a single signature serves the whole company.
Nothing goes live blind.
Before a signature is switched on, the details page shows exactly what a recipient will see.
fixsignatures.com makes the promise in a single line and then lets the product prove it.
04 — Where it stands
Every mailbox, the same signature.
Three Outlook clients kept in line, not a single email read along the way, and a 30-day trial that does not ask for a card.
