  • STEP 2: Open Mozilla Thunderbird Mail on your mac.

  • STEP 3: Once Mozilla Thunderbird Mail is open, select Tools from the menu bar (top right), then select the Account Settings menu option.


  • STEP 4: In the Account Settings window, go to the Signature Text section. IMPORTANT In order to use HTML code you need to check the Use HTML box.


  • STEP 5: Paste your HTML code into the Signature Text field by pressing Command + V.


  • STEP 6: Close your account settings window and compose a new email or reply to an email. Your email signature should be automatically inserted into your emails.
