A Mac OS Mail signature is a customizable block of text and images that includes your name, title, contact information, logo, and more. It's automatically inserted at the end of your Email Messages sent via Apple’s Mail app.

A professional email signature can also include links to your home page, social media profiles, and even a handwritten signature on Mac for a personal touch.

Is the Mac Mail Signature Free?

Yes! If you're using Apple Mail, the built-in email signature generator free Mac users get is 100% free to use.

You can create and manage multiple signatures, assign them to different email accounts, and customize them using basic formatting tools.
