Mac OS X Mail and macOS Mail make it easy to insert text links into your email signature—all you have to do is type the URL. You can also add an image to your signature and add a link to it.

Add Text Links to Signatures in Mac OS X Mail or MacOS Mail

To insert a link in your Mac OS X Mail signature, just type the URL. Inserting anything that starts with http:// is usually sufficient for recipients to be able to follow the link. You can also set up some of the text in your email signature to link to a website or blog.

To link existing text in a Mac OS X Mail or macOS signature:

  1. Open the Mail application and click Mail in the menu bar. Select Preferences from the menu.
  2. Click the Signatures tab and select the account with the signature you want to edit in the left column of the screen. Select the signature from the middle column. (You can also add a new signature here by pressing the Plus sign.) 
  3. In the right panel, highlight the text you want to link in the signature. 
  4. Select Edit  > Add Link from the menu bar or use the keyboard shortcut Command + K.
  5. Enter the complete internet address including http:// in the field provided and click OK.
  6. Close the Signatures window.

Add Image Links to Signatures in Mac OS X Mail or MacOS Mail

  1. Size the image—your business logo, business card, or other graphic—to the size you want it to display in the signature.
  2. Open the Mail application and click Mail in the menu bar. Select Preferences from the menu.
  3. Click the Signatures tab and select the account with the signature you want to edit in the left column of the screen. Select the signature from the middle column.
  4. Drag the image you want to the signature screen.
  5. Click on the image to select it.
  6. Select Edit  > Add Link from the menu bar or use the keyboard shortcut Command + K.
  7. Enter the complete internet address in the field provided and click OK.
  8. Close the Signatures window.

Test the Signature Links

Test that your signature links were saved properly by opening a new email in the account with the signature you just added. Select the correct signature from the drop-down menu next to Signature to display the signature in the new email. The links won't work in your draft email, so send a test message to yourself or to one of your other accounts to confirm that the text and image links work properly.

Note that rich text links do not display in the plain text equivalent that Mac OS X Mail and macOS Mail automatically generate for recipients who prefer to read their mail in plain text.
