How to add an HTML email signature in Outlook

Outlook comes in several versions, but every one accepts a pasted, formatted signature. Copy once from DigiSignature, then follow the steps for your version.

  1. 1

    Copy your signature

    In DigiSignature, open your signature and click Copy signature.

  2. 2

    New Outlook & Outlook on the web

    Click the gear icon → Account → Signatures. Click + New signature, name it, and paste into the editor.

  3. 3

    Classic Outlook for Windows

    Go to File → Options → Mail → Signatures. Click New, name it, then paste into the Edit signature box.

  4. 4

    Outlook for Mac

    Open Outlook → Settings → Signatures. Click +, name it, and paste into the editor on the right.

  5. 5

    Choose your defaults

    Pick this signature for new messages and for replies/forwards in each account.

  6. 6

    Save and test

    Click Save (or OK), then send a test email to yourself and to a Gmail address to check how it looks.

Good to know

  • Signatures don't always sync between Outlook versions. Install it on each device your team uses.
  • Classic Outlook for Windows can add extra spacing. DigiSignature signatures are built with tables to keep layouts tight.
  • Use Outlook's dark mode preview to check your logo — a transparent PNG with a light outline works best.
