Add a signature so your name appears at the bottom of every email

A signature in Yahoo Mail is a block of text that appears automatically at the end of every message you send. It usually contains your name, phone number, job title, or any other information you want recipients to see. You set it once in your settings, and Yahoo Mail adds it to outgoing emails without you having to type it each time.

The process takes about two minutes and works the same way whether you use Yahoo Mail on a computer or phone. You can create one signature that applies to all your emails, or set different signatures for different email accounts if you have more than one.

Key Takeaways

  • Signatures are created in Yahoo Mail settings, not in the compose window, so the change applies to all future emails.
  • You can include line breaks, your phone number, a website, or any text you want — but not images or formatted fonts.
  • If you have multiple Yahoo Mail accounts, each account has its own separate signature.
  • You can turn your signature off for individual emails if you need to send a message without it.

Create a signature on a computer

Open Yahoo Mail in your web browser and look for the gear icon in the top right corner of the screen. Click it and select Settings from the dropdown menu. This opens your account settings page.

On the left side of the settings page, click Composing email. Scroll down until you see the Signature section. In the text box under "Signature", type whatever you want to appear at the bottom of your emails. You can include your name, phone number, a job title, or a short message — whatever makes sense for your situation.

Once you have typed your signature, scroll to the bottom of the page and click Save. Yahoo Mail will now add your signature to every email you send going forward. You do not need to do anything else — it happens automatically.

Create a signature on your phone

Open the Yahoo Mail app on your phone. Tap the three horizontal lines (called a menu icon) in the top left corner. Scroll down and tap Settings.

Look for your email account in the list and tap it. Then tap Signature. Type your signature in the text box that appears. When you are done, tap Save or the back arrow to return to settings. Your signature is now active on your phone.

Edit or remove your signature

To change your signature later, go back to the same place you created it. On a computer, open Settings, click Composing email, and find the Signature section. Delete the old text and type the new signature, then click Save. On your phone, follow the same steps through Settings and tap your account, then tap Signature and make your changes.

To remove your signature entirely, delete all the text in the signature box and click Save. Yahoo Mail will stop adding a signature to your emails. You can add one back at any time by following the same steps.

What you can and cannot include in a signature

Yahoo Mail signatures accept plain text only. You can type your name, phone number, email address, website URL, job title, or a short personal message. You can press Enter to create line breaks, so your signature can span multiple lines if you want it to.

You cannot add images, colored text, bold or italic formatting, or special fonts to a Yahoo Mail signature. If you paste formatted text from another program, Yahoo Mail will strip away the formatting and leave only the plain text. This keeps signatures simple and ensures they display the same way for everyone who receives your email.

Send an email without your signature

Sometimes you may want to send a message without your signature attached. When you are composing an email, look for a small dropdown arrow or menu icon near the signature area at the bottom of the compose window. Click it and select the option to remove or turn off the signature for that email only.

This setting applies only to that single message. Your signature will be back on the next email you send. If you cannot find this option in your compose window, you can manually delete the signature text before sending — just highlight it and press Delete.

Troubleshooting signatures that do not appear

If you created a signature but it is not showing up on your emails, first check that you clicked Save after typing it. Many people type their signature and forget to save, so the change never takes effect. Go back to Settings, Composing email, and verify that your signature text is still there.

If your signature is saved but still not appearing, try logging out of Yahoo Mail completely and logging back in. Sometimes the change does not take effect until you refresh your session. If you are using the Yahoo Mail app on your phone, try closing the app completely and opening it again.

Another common issue: if you have multiple Yahoo Mail accounts, make sure you are checking the right account. Each account has its own separate signature, so a signature you created on one account will not appear on emails from a different account.

Frequently Asked Questions

Can I have different signatures for different types of emails?

Yahoo Mail does not support multiple signatures within one account. You have one signature that appears on all emails from that account. If you need different signatures for work and personal emails, you would need to create a separate Yahoo Mail account for each purpose.

Will my signature appear on emails I forward or reply to?

Yes. When you reply to or forward an email, your signature appears at the bottom of your new message, below the original email text. If you do not want your signature on a particular reply, you can delete it manually before sending.

What happens to my signature if I change my password?

Your signature is separate from your password and will not be affected by password changes. It stays in place and continues to appear on all your emails.

Can I use special characters or emojis in my signature?

Yes, you can type special characters and emojis directly into the signature box. They will appear in your emails the same way they appear when you type them. Keep in mind that some older email programs may not display emojis correctly, so test with a recipient if you are unsure.

Is there a character limit for signatures?

Yahoo Mail does not publish a specific character limit, but signatures work best when kept short — typically under 500 characters. Very long signatures can make emails harder to read and may cause display issues on some devices.
