How to Setup Your Yahoo Mail Signature

Email signatures are a standard feature in most email applications, and you may add one to your Yahoo Mail account with a few changes to your settings.

Note that the process for changing your email signature varies slightly depending on if you are using Yahoo Mail or the Classic Yahoo Mail. Instructions for both versions appear here.

An email signature in Yahoo Mail is automatically appended at the bottom of every reply, forward, and new message you create.

A signature can include nearly anything; users often add their name and important contact information, such as email address, phone number, and a website address. You may even include marketing taglines, witty quotes, or links to your social media accounts, for example.

Adding a Yahoo Mail Signature

These instructions detail how to add an email signature in the updated version of Yahoo Mail.

  1. Open Yahoo Mail.
  2. Click the Settings icon in the upper right of the screen.
  3. From the menu, click More Settings.
  4. In the left menu, click Writing email.
  5. In the Writing emails section to the right of the menu, under Signature, locate the Yahoo Mail account you want to add a signature to and click the switch to the right of it. This action opens a text box beneath it.
  6. In the text box, enter the email signature you want to be appended to email messages that will be sent from this account.
    1. You have several formatting options, including bolding and italicizing text; changing the font style and font size; adding color to text, as well as a background color; inserting bullet points; adding links; and more. You can see a preview of how your signature will appear to the left, under Preview message.
  7. When you have completed entering your signature and are satisfied with its appearance, click Back to inbox in the upper left. Your signature is saved automatically, so there's no save button you need to press.

    All emails you compose will now include your signature.

    Adding an Email Signature to Classic Yahoo Mail

    If you're using the classic version of Yahoo Mail, follow these steps to create an email signature:

    1. Click the Settings button (it appears as a gear icon) in the upper right corner of the page.
    2. In the lefthand menu of the Settings window, click Accounts.
    3. To the right under Email addresses, click the Yahoo account for which you want to create an email signature.
    4. Scroll down to the Signature section and check the box next to Append a signature to the emails you send.
      1. Optional: Another checkbox available is labeled Include your latest Tweet from Twitter. If you check this box, an authorization window will open asking you to grant Yahoo Mail access to your Twitter account. This allows Yahoo Mail to read your Tweets, to see those you follow, to follow new people, to update your profile, and to post Tweets for you. It does not give Yahoo Mail access to your Twitter password or the email address associated with your Twitter account, nor does it give access to your direct messages on Twitter.
      2. Click Authorize app if you wish to grant Yahoo Mail access to your Twitter account to include your most recent Tweet in your email signature automatically.
    1. In the text box, enter your email signature. You may format text in your signature using bold, italics, different font styles and sizes, background and text colors, links, and more.
    2. When you are happy with your email signature, click Save at the bottom of the window.

    Yahoo Basic Mail

    There is a stripped-down version called Yahoo Basic Mail, and in this version there are no formatting options for emails or signatures. If you're in this version, your email signature will be in plain text.

    Disabling Your Yahoo Mail Signature

    If you no longer want to automatically include a signature in your emails, you can easily turn it off by returning to the signature settings.

    In Yahoo Mail, click Settings More Settings Writing email and click the switch next to your Yahoo Mail email address to toggle the signature off. The signature editing box will disappear; however, your signature is saved in case you want to reactivate it later. 

    In Classic Yahoo Mail, click Settings Accounts and click the email account for which you want to disable the email signature. Then uncheck the box next to Append a signature to the emails you send. The email signature box will gray out to indicate it is no longer active, but your signature is still saved in case you wish to reactivate it again in the future.

    Online Tools for Creating Email Signatures

    If you don't want to do all the setup and formatting of an email signature, tools are available that allow you to generate and apply an email signature template with a professional appearance. These tools often include additional features, such as formatted Facebook and Twitter buttons. 

    Some of the email signature tools may include a branding link back to the generator that is also included in your signature when you use their free versions—but the companies offer an option for you to pay to exclude the branding. They may also request additional information about you, such as your title, company, and how many people work at your company, for example, in exchange for using the free generator.

    HubSpot offers a free Email Signature Template GeneratorWiseStamp also offers a free email signature generator (along with a paid option to remove their branding).
