How to add an HTML email signature in any webmail

Nearly every webmail and email tool has a rich-text signature editor. If it lets you bold text, it can take a DigiSignature signature with a simple paste.

  1. 1

    Copy your signature

    In DigiSignature, open your signature and click Copy signature.

  2. 2

    Find signature settings

    Look for Settings → Signature (Yahoo, Fastmail, Roundcube), Settings → Identity (Proton Mail) or Settings → Mail → Signature (Zoho).

  3. 3

    Use the rich-text editor

    Make sure the editor is in rich text or HTML mode, not plain text.

  4. 4

    Paste it in

    Click into the box and paste. If the tool has a source or </> button, you can paste the HTML code there instead.

  5. 5

    Save and test

    Save, then send a test email to a Gmail and an Outlook address to see it the way your recipients will.

Good to know

  • Some webmail tools strip tracked links or images on paste. Pasting into the HTML/source view usually avoids this.
  • Keep signatures under about 10 KB of code — DigiSignature layouts are built to stay well inside common limits.
  • Using a CRM or help desk? The same copy-and-paste works in most of their signature editors too.
