How do I prevent images in my Apple Mail signature from appearing as attachments to the recipient?

3. Edit the Raw HTML of Your Apple Mail Signature

If you’re comfortable with HTML, you can manually edit your Apple Mail signature to include hosted images.

Steps:

1. Create a Signature in Apple Mail:
   • Go to Mail > Preferences > Signatures and create a new signature with placeholder content.
2. Locate the Signature File:
   • Navigate to the folder: ~/Library/Mail/V<version>/MailData/Signatures/.
   • Open the .mailsignature file associated with your signature using a text editor.
3. Insert Hosted Image URLs:
   • Replace image placeholders with hosted URLs:
   • html
   • Copy code
   • <img src="https://example.com/image.png" alt="Logo" style="max-width: 200px; height: auto;">

4. Lock the File (Optional):
   • To prevent Apple Mail from overwriting the changes, lock the file:
     • Right-click the .mailsignature file and select Get Info.
     • Check the Locked box.
5. Restart Apple Mail:
   • Relaunch Apple Mail to apply the changes.

Best Practices to Ensure Images Don’t Appear as Attachments

1. Always Use Hosted Images:
   • Avoid embedding images directly into the email body or attaching them as files.
2. Test Across Email Clients:
   • Send test emails to different email clients (e.g., Gmail, Outlook) to verify the images render correctly.
3. Compress Images:
   • Optimize the file size of your images to ensure faster loading and better compatibility.
4. Use HTTPS Links:
   • Ensure image URLs are secure (https://) to avoid them being blocked by email clients or firewalls.
