How to Create & Add a Signature in Yahoo Mail

Brought to you by Exclaimer

Yahoo Mail continues to be one of the most widely used email clients worldwide. With approximately 227.8 million active users as of 2022, Yahoo Mail has been a mainstay of personal and business emails since its launch back in 1997.

No matter what type of user you are, it is best practice to create and add a signature in Yahoo Mail to accurately provide your contact details to external recipients. Including a Yahoo email signature is a great way to humanize your messages and tell people how to easily contact you. This personalized signature template will then appear on the bottom of every email you send.

For business communications, look to include the following details:

  • Full name
  • Job title
  • Phone number
  • Company name
  • Email address

Yahoo Mail does not apply signatures by default. This means you need to active the feature within the email client itself. This can be done by either logging into Yahoo Mail on a desktop or on the Yahoo Mail mobile app.

How to add a signature in Yahoo Mail on a desktop

1. Sign in to your Yahoo Mail account from a web browser (via yahoo.com).

2. Select Settings in the top right corner of the screen.

3. From the dropdown, click More Settings.

4. Select Mailboxes.

5. From the mailbox list, choose the email address you want the Yahoo signature to be applied to.

Choose the email address you want to use to add a signature in Yahoo Mail.

6. Scroll down to the Signature box. This will likely be greyed out, so click the Signature toggle switch to activate the signature editor.

Active the Yahoo signature text box.

7. In the signature section where it says, “Write something…”, add your signature content. When you add a signature in Yahoo Mail, think about the text, formatting, and imagery. The tools available will let you create a basic professional email signature template.

Write the content for your Yahoo email signature

You should also consider including links to specific calls-to-action (CTAs) in order to make your Yahoo signature offer more to recipients. Links to your website and important content will help drive more valuable conversations.

To include add an image such as a social media icon to your Yahoo email signature, you will need to use a third-party signature generator. You cannot natively use HTML images when adding a signature in Yahoo Mail.

8. When you’re having with your Yahoo Mail signature, click Save.

8. When complete, tap the back arrow in the top left of your screen to save your new Yahoo signature.
