    1

    Set up a signature in Gmail (on a computer)

    ~40s
    Open Gmail in a web browser. Click the gear icon (Settings) in the top right corner, then click See All Settings. Scroll down the General tab to find the Signature section. Click Create New. Give the signature a name (like "My Signature"), then type your signature text in the box below. Below the text box, find the dropdowns for "For New Emails Use" and "On Reply/Forward Use" — select your new signature from both menus. Scroll to the bottom of the page and click Save Changes.

    Quick Tip

    Quick Tip: The signature editor in Gmail on a computer lets you bold text, change font sizes, and add a photo. Keep it simple — plain text works perfectly and looks clean on all devices.

    Set up a signature in the Gmail app (on your phone)

    ~24s
    Open the Gmail app. Tap the three horizontal lines (menu) in the top left, then scroll all the way down and tap Settings. Tap your email address. Scroll down and tap Mobile Signature. Type your signature text — your name, phone number, and any other details. Tap OK or Save. Your signature will appear at the bottom of new emails you compose in the app.

    Set up a signature in iPhone Mail

    ~26s
    Open the Settings app on your iPhone and scroll down to Mail. Tap Signature. You will see a text box for your signature. Type your signature. If you have multiple email accounts set up, you can choose "Per Account" at the top to set different signatures for each account, or leave it on "All Accounts" for the same signature everywhere. Your signature will now appear in every new email you write in the iPhone Mail app.
    4

    Set up a signature in Microsoft Outlook app

    ~21s
    Open the Outlook app on your phone. Tap your profile photo or initials in the top left corner, then tap the gear icon (Settings). Scroll down and tap Signature. Toggle on the signature option, then type your signature text in the box. Tap the checkmark or Save. Outlook will add your signature to every new email you compose.
    5

    Test your new signature

    ~18s
    Open your email app and start composing a new message. Your signature should appear automatically at the bottom of the email body. If it does not appear, go back to the settings steps above and make sure the signature was saved correctly. Once confirmed, you will see it on every new email going forward.

    An email signature is text that appears automatically at the bottom of every email you send. Instead of typing your name and phone number at the end of every message, you set it up once and it is added for you every time.

    A typical email signature includes: - Your full name - Your phone number - Your email address - Optionally: your job title, the name of your business, your website, or a brief tagline

    Signatures are especially useful when emailing people who do not have your contact information, like a doctor's office, a contractor, or a new acquaintance. It removes the need to ever type "Best regards, Jane — 555-123-4567" manually.

    You can set up a signature in almost every email app. This guide covers three of the most common: Gmail (both in a web browser and the Gmail app), the iPhone's built-in Mail app, and the Microsoft Outlook app.

    Keep signatures concise. A signature with your name, phone number, and one or two other details is professional and quick for recipients to read. Very long signatures with lots of formatting can look cluttered on mobile devices.

    Setting up a signature takes about two minutes, and once saved you never have to think about it again.
