Why InboxSign for Outlook?

96 DPI Optimization

We optimize your logo DPI so it never appears giant or blurry in the Outlook desktop app.

Table-Based Layout

Using robust HTML tables ensures your layout doesn't collapse in the Microsoft Word engine.

Got Questions? We Have Answers.

Common technical hurdles for Outlook signatures solved.

Why does Outlook change my font?

Outlook defaults to Times New Roman if the font isn't standard. We use web-safe font stacks to prevent this.

Does this work with the 'New' Outlook?

Yes, our signatures are fully compatible with both Classic Outlook and the new web-based Outlook.
