Frequently asked questions
How do I add a signature in Outlook? +
Outlook desktop: File → Options → Mail → Signatures → New, paste, set as default. New Outlook & web: Settings → Mail → Compose and reply → New signature.
Why does my Outlook signature look broken? +
Outlook desktop uses Microsoft Word's rendering engine, which doesn't support modern CSS. Sigavo signatures use table-based HTML with inline styles — the safest approach for Outlook.
Can I use the same signature on Outlook desktop and web? +
Yes, but Outlook does not sync signatures automatically. Build it once with Sigavo, then paste into both Outlook desktop and Outlook on the web.
My logo doesn't appear in Outlook. What went wrong? +
Use a publicly accessible HTTPS URL for your logo. Outlook may strip images that come from blocked or private hosts. Avoid Google Drive / Dropbox links.
Does Sigavo work with Microsoft 365 business email? +
Yes. The signature you build works for Outlook on any Microsoft 365 plan — personal, business or enterprise.
