Create a Signature in Apple Mail

  1. To create a signature in Mail, select Preferences from the Mail menu.
  2. In the Mail Preferences window, click the Signatures icon.
  3. If you have more than one email account, select the account for which you want to create a signature.
  4. Click the plus (+) icon near the bottom of the Signatures window.
  5. Enter a description for the signature, such as Work, Business, Personal, or Friends. If you want to create multiple signatures, be sure to use descriptive names, to make it easier to tell them apart.
  6. Mail will create a default signature for you, based on the email account you selected. You can replace any or all of the default signature text by typing or copy/pasting new information.
  7. If you want to include a link to a web site, you can enter just the main part of the URL, rather than the entire URL. For example, mybusiness.com rather than http://www.mybusiness.com or www.mybusiness.com. Mail will turn it into a live link.
  8. If you would like to add an image or vCard file to your signature, drag the image or vCard file to the Signatures window. Take pity on the recipients of your email, and keep the image fairly small.
  9. Put a check mark next to “Always match my default message font” if you want your signature to match the default font in your messages.
  10. If you want to select a different font for your signature text, highlight the text, and then select Show Fonts from the Format menu.
  11. Select the font, typeface, and font size from the Fonts window. Your selection will be reflected in the Signatures window.
  12. If you want to apply a different color to some or all of the text in your signature, select the text, select Show Colors from the Format menu, and then use the slider to select a color from the color wheel.
  13. When you reply to an email message, your response will usually include text quoted from that message. If you want your signature to be placed above any quoted text, place a check mark next to “Place signature above quoted text.” If you don’t select this option, your signature will be placed at the very bottom of the email, after your message and any quoted text, where the recipient may never see it.
  14. When you’re satisfied with your signature, you can close the Signatures window, or repeat the process to create additional signatures.

Apply a Default Signature to an Email Account

  1. To select a default signature, select Preferences from the Mail menu.
  2. In the Mail Preferences window, click the Signatures icon.
  3. If you have more than one email account, select the account you want to apply a signature to.
  4. From the Choose Signature dropdown menu at the bottom of the Signatures window, select the desired signature.
  5. Repeat the process to add default signatures to other email accounts, if any.
  6. Close the Signatures window.

Apply a Signature on the Fly (Ad Hoc)

  1. If you don’t want to apply a default signature to an email account, you can instead select a signature on the fly.
  2. Click the New Message icon in the Mail viewer window to create a new message.
  3. On the right side of the New Message window, you’ll see a Signature dropdown menu. After you finish writing your message, select the desired signature from the Signature dropdown menu, and it will magically appear in your message. The Signature dropdown menu is also available when you reply to a message.
  4. If you selected a default signature for an email account, but you don’t want to include the signature in a particular message, just select None from the Signature dropdown menu.
