Create an Email Signature in Mac Mail

This article shows you how to add an email signature in Mail for Mac OS X.

You can have multiple signatures to select from when you send an email. Signatures can be added automatically when you compose an email or you can choose a signature as the email is being composed.
To create a signature:

  1. Open Mail.
  2. Navigate to Preferences from the Mail application menu.
  3. Select the account from the left side bar and click Signatures.
  4. If you wish to add a signature for all accounts, select the All Signatures option. Otherwise adding a signature to a specific account, select that specific account.
  5. Click the + sign to add a new signature to the account. Name the signature so you know what it is and then add the signature in the right box. In the example below, we added two signatures: one named Signature #3 and one named Signature #4.
  6. From the drop down, you can choose a signature as the default for the mail account when composing a message. This signature is automatically added to each message you compose.
  7. To choose a signature when you compose a message, select Signature in the Compose a Message screen drop down. This signature is then added to your message.
