What is an Email Signature in Outlook?
A signature in Outlook is a personalized block of text, images, or links that automatically appears at the bottom of your outgoing messages. Think of it as your digital business card; it typically includes your name, job title, and phone number, but it can also feature a company logo or social media icons. Instead of typing your sign-off every time you hit “Send,” setting up a signature ensures your emails always look professional and provide recipients with an easy way to find your contact details.
