  4. Paste Your Signature — Click inside the signature editor box and press Ctrl+V (or Cmd+V on Mac) to paste your copied signature.
  5. Set as Default — Under "Signature defaults", select your new signature for both "For new emails use" and "On reply/forward use".
  6. Save Changes — Scroll to the bottom of the page and click "Save Changes".

OOutlook (Web & Desktop)

Outlook on the Web (outlook.com)

  1. Open Settings — Click the gear icon in the top-right, then click "View all Outlook settings".
  2. Navigate to Signatures — Go to Mail → Compose and reply.
  3. Edit Your Signature — Click inside the signature editor and press Ctrl+V to paste.
  4. Set Defaults — Choose your signature for new messages and replies, then click "Save".

Outlook Desktop (Windows)

  1. Open Signature Settings — Go to File → Options → Mail → Signatures.
  2. Create New — Click "New", give it a name, and paste your signature into the editor with Ctrl+V.
  3. Set Defaults — Select your signature under "New messages" and "Replies/forwards", then click OK.

Tip: In Outlook Desktop, you may need to use Ctrl+Shift+V or right-click and choose "Keep Source Formatting" to preserve the design.

AApple Mail (macOS)

  1. Open Preferences — In Apple Mail, go to Mail → Settings (or Mail → Preferences on older macOS versions).
  2. Go to Signatures Tab — Click the "Signatures" tab at the top of the settings window.
  3. Add a New Signature — Select your email account on the left, then click the "+" button at the bottom.
  4. Paste Your Signature — Click in the right-hand preview pane and press Cmd+V to paste your signature.
  5. Uncheck "Always match my default font" — This is important. If this box is checked, Apple Mail will strip your signature's formatting.
  6. Set as Default — At the bottom, set "Choose Signature" to your new signature.

Important: You must uncheck "Always match my default message font" in the signature settings, otherwise your formatting will be lost.

TThunderbird

  1. Open Account Settings — Go to Edit → Account Settings (or Tools → Account Settings on some systems).
  2. Select Your Account — Click on your email account in the left sidebar.
  3. Enable HTML Signature — Tick the box that says "Use HTML" below the signature text area.
  4. Paste the HTML — Paste your copied signature into the signature text area using Ctrl+V.
  5. Click OK — Your signature will now appear on all new emails and replies.

Tip: Make sure "Use HTML" is checked. Without it, Thunderbird will display the raw HTML code instead of the formatted signature.

Troubleshooting

Images not showing?

Make sure your image URLs are publicly accessible. Images hosted behind a login, on localhost, or as base64 data will not display in most email clients. Use a service like Imgur, Cloudinary, or your company's website to host images.

Formatting looks wrong after pasting?

Some email clients strip formatting when pasting. Try using Ctrl+Shift+V (paste without formatting) and then re-paste with Ctrl+V. In Apple Mail, make sure "Always match my default message font" is unchecked.

Signature looks different on mobile?

Email signatures on mobile devices may appear differently due to smaller screens. Our templates use table-based layouts that work well on both desktop and mobile, but very long signatures may wrap differently on smaller screens.
