Why Outlook signatures break

Outlook is notorious for mangling pasted signatures — swapping fonts, resizing logos and dropping spacing. ProSignature builds signatures with the inline, email-safe HTML Outlook expects, so what you design is what your recipients see.

Add it to Outlook in a few steps

Design your signature in the generator.
Copy it with the one-click Copy button.
In Outlook go to Settings → Mail → Compose and reply (or Insert → Signature on desktop).
Paste it in and set it as your default for new messages and replies.

Works across every version of Outlook

The same signature works in the new Outlook, classic Outlook desktop, Outlook on the web and Microsoft 365. Need it for your whole company? Deploy branded signatures to everyone with the team plan, or set one up for Gmail too.

FAQ

Frequently asked questions

How do I add an HTML signature with a logo in Outlook?

Design it in ProSignature, click Copy, then paste it into Outlook's signature editor under Settings. Because the signature uses inline email-safe HTML, the logo and layout stay intact.

Does this work with the new Outlook and Outlook on the web?

Yes. The signature works in the new Outlook, classic desktop Outlook, Outlook on the web and Microsoft 365.

Why does my Outlook signature look broken when I paste it elsewhere?

Most signatures break because they use unsupported CSS. ProSignature builds with inline styles that Outlook renders reliably, which is why the paste holds together.
