  2. Copy the entire signature
  3. Go to Settings → Mail → Signature
  4. Paste the signature
  5. Shake to undo automatic formatting changes
  6. Quickly tap elsewhere to save
Note: This method may lose some formatting. Icons might appear as attachments.

Option 3: Email to Yourself

  1. Create signature on computer
  2. Email it to yourself
  3. Open on iPhone and select all
  4. Copy the signature
  5. Paste in Settings → Mail → Signature

<head>
<meta charset="UTF-8">
</head>
<body>
<div>
<!-- Your signature content -->
<p>John Smith<br>
Marketing Director<br>
Company Name</p>

<!-- Social Icons -->
<table cellpadding="0" cellspacing="0" border="0">
<tr>
<td style="padding-right:5px;">
<a href="https://linkedin.com/in/profile">
<img src="https://www.niftybuttons.com/icons/linkedin.png"
width="24" height="24" alt="LinkedIn">
</a>
</td>
<td style="padding-right:5px;">
<a href="https://twitter.com/handle">
<img src="https://www.niftybuttons.com/icons/twitter.png"
width="24" height="24" alt="Twitter">
</a>
</td>
</tr>
</table>
</div>
</body>
</html>

  2. Close Mail completely
  3. Open Terminal

    cd ~/Library/Mail/V*/MailData/Signatures/

Troubleshooting Common Issues

Solutions:
  • Enable "Load remote content" in Mail → Settings → Viewing

  • Consider embedding images as base64 data URIs
  • Check recipient's email client compatibility

Solutions:
  • Lock the signature file after editing (see Advanced Method)
  • Ensure "Always match my default message font" is unchecked
  • Don't edit the signature in Mail after adding HTML
  • Use our signature generator for stable formatting

Solutions:
  • Use externally hosted images instead of embedded
  • Ensure images are properly linked with <img> tags
  • Use PNG format with transparent backgrounds

Solutions:
  • Use iCloud Mail for automatic syncing
  • For other accounts, set up signatures separately
