Hello elmoshamu,

"Create and use email signatures in Mail on Mac

You can create prepared text, called a signature, to include when you send email messages. For example, you can create one signature for your work email and another signature for your personal email.

Create signatures

1. In the Mail app  on your Mac, choose Mail > Settings, then click Signatures.
2. In the left column (account list), select the email account where you want to use the signature.
3. If All Signatures is selected when you create a signature, you need to drag the new signature to the desired email account before you can use it.
4. Click the Add button  below the middle column.
5. In the middle column (signature list), type a name for the signature. 
6. This name appears in the Signature pop-up menu when you write a message.
7. In the right column (the preview), do any of the following to create your signature:

• Edit your text: Click Edit in the menu bar to paste text, turn text into links, and check spelling and grammar.
• Format your text: Click Format in the menu bar to change the font and color, change text alignment, and add lists.
• Add an image: Drag an image into the preview area.

If you want your signature to appear after the original text of messages you reply to or forward, deselect the “Place signature above quoted text” checkbox.

Delete signatures

1. In the Mail app  on your Mac, choose Mail > Settings, then click Signatures.
2. Select a signature in the middle column, then click the Remove button . 

When you delete a signature from All Signatures, it’s deleted from any account that uses it.

Automatically add a signature to emails

You can choose a signature to automatically add to messages you send.

1. In the Mail app  on your Mac, choose Mail > Settings, then click Signatures.
2. Select an account in the left column.
3. Click the Choose Signature pop-up menu, then choose a signature. 
4. If you have more than one signature for an account, Mail can automatically alternate between them—choose At Random or In Sequential Order from the pop-up menu. 

If you want to stop having a signature automatically added to your messages, click the Choose Signature pop-up menu, then choose None.

Note: A signature isn’t automatically added to messages you send from a unique, random address created with Hide My Email.

Add a signature to emails yourself

1. In the Mail app  on your Mac, click the Signature pop-up menu in the message you’re writing. 
2. Choose a signature.
3. If an expected signature isn’t in the Signature pop-up menu, or the menu isn’t showing, choose Mail > Settings, click Signatures, then verify the signature has been added to the correct email account.

Remove a signature from emails

1. In the Mail app  on your Mac, in a message you’re writing, click the Signature pop-up menu.
2. Choose None.

Depending on how a recipient’s Mail server handles signatures, your signature may appear as an attachment or image to the recipient.

If you use iCloud Drive on your Mac and other devices, and have Mail selected in iCloud Drive options, your signatures are automatically updated and available on those devices. 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. You can also use the Preview app to fill out and sign PDF forms."

We hope this helps.

Cheers!
