Microsoft Outlook is one of the most popular email clients worldwide, but its signature editor has quirks. This guide walks you through creating a professional signature with SigCraft and installing it in Outlook 2019, Outlook 365, and Outlook on the web.
SigCraft generates email-client-proof HTML that works in Outlook — but Outlook uses Microsoft Word's rendering engine, so installation steps differ from Gmail. Make sure you are using Outlook 2019 or later for the best results.

Go to the SigCraft signature builder and create your signature. Use the AI input to describe yourself, or fill in the form manually. Choose a template, set your brand color, and upload an avatar. The live preview shows exactly what your signature will look like.
Click the "Copy HTML" button in the SigCraft builder. This copies the compiled HTML to your clipboard. Unlike other methods, you will paste this as a file in Outlook, not directly into the editor.
Outlook 2019 / 365 (Windows):
Outlook on the web:
⚠ Important: On Windows Outlook, pasting HTML directly into the signature editor often strips formatting. The reliable method is to paste as a file. Open Notepad, paste the HTML (Ctrl+V), save as signature.html, then open that file in a browser, copy the rendered output, and paste into Outlook's signature editor.
Method 1 — Windows Outlook (recommended):
Method 2 — Outlook Web:
Windows Outlook: In the Signatures and Stationery window, choose your new signature for "New messages" and "Replies/forwards" from the dropdown menus. Click OK.
Outlook Web: Select your signature in the "Default signature" dropdown and click Save.
Create a new email to see your signature in action. Send a test message to yourself to verify the signature renders correctly. If images are blocked, click "Click here to download pictures" — this is normal Outlook behavior.
Outlook's signature editor strips HTML when pasting directly. Use Method 1 above: paste into a new email first, then copy from there and paste into the signature editor.
Outlook blocks external images by default. Recipients see "Click here to download pictures." This is normal for all HTML signatures. Your avatar and social icons are hosted on Cloudflare R2 and will load once approved.
Outlook uses Microsoft Word's rendering engine, which handles CSS differently than web browsers. SigCraft generates table-based HTML specifically tested for Outlook compatibility.

Use the "Insert as Text" option in Outlook's signature editor. Do not paste directly into the edit field — use the "Attach file" > "Insert as Text" method to preserve formatting.

Yes. Outlook for Mac uses a different editor than Windows. You can paste the compiled HTML directly into the signature editor. Make sure to select HTML format from the Edit menu.
Outlook only renders system fonts (Arial, Verdana, Times New Roman, etc.). SigCraft uses web-safe fonts exclusively, so your signature will use the closest available system font on the recipient's device.
