Change Signatures settings in Mail on Mac

Use Signatures settings in Mail to create signatures you can add to messages you send.

To change these settings in the Mail app on your Mac, choose Mail > Settings, then click Signatures.

Option				Description
Left column				Choose signatures to work with by clicking All Signatures or an email account.
Middle column				The list of signatures in All Signatures or an account. To edit a signature for an account, click the account in the left column, then click a signature in the middle column. When All Signatures is selected, you can add an existing signature to another account by dragging the signature from the middle column to the account in the left column. You can use the same signature in more than one account.
Add , Remove				Create a new signature for the selected account or remove a signature. If you create a signature while All Signatures is selected in the left column, you must drag the signature to an account before you can use it.
Right column				Enter the text of your signature, change formatting, add images, and preview how your signature looks. To change the font or layout, turn text into links, or check spelling, use the Edit and Format menus in Mail. To add an image, drag one into the column. To quickly include your contact information, drag your card from the Contacts app into the column.
Always match my default message font				The selected signature uses the message font specified in Fonts & Colors settings.
Choose Signature				Select a default signature to automatically include in your messages for the selected account, or instead use all of the account’s signatures in sequential or random order.
Place signature above quoted text				Position your signature when you reply to or forward a message.

If you use iCloud Drive, your signatures are available on your other Mac computers that have iCloud Drive turned on and Mail selected in iCloud Drive options. See Use iCloud Drive to store documents.

If you need to send a signed PDF document, you can use Markup in Mail to create a handwritten signature and add it to the document. Or use the Preview app. See Fill out and sign PDF forms.
