You’ll see an option labeled **Signature** with a toggle switch. If the switch is turned off, toggle it on to enable your signature. 2. Once enabled, a text box will appear where you can create or edit your signature. If you already have a signature, you can modify it here. ## **Step 5: Add Your Phone Number** 1. In the signature text box, type your desired signature. To add your phone number, you can write it directly under your name, like this: ![](https://support.800.com/hubfs/Knowledge%20Base%20Import/zd-33097417298189-3b13741f6748df7f-AD_4nXf7pPm8Yh-bqEWkeF9sCjsMxwdM_AUMdvwI5ZkSJpl8s_d3ijNsA24r-2.png) - You can also add additional contact details, such as an email address or website, if needed. Feel free to use formatting options like bold, italics, or different fonts to enhance the appearance of your signature. ## **Step 6: Save Your Changes** 1. Once you’ve finished adding your phone number and any other information, scroll down and click the **Save** button at the bottom of the screen. 2. Your changes are now saved, and your new signature, including your phone number, will automatically appear at the bottom of all outgoing emails. ## **Step 7: Test Your Signature** Finally, it's always a good idea to send yourself an email to make sure your phone number appears as expected. If you included a clickable link, test that it works on mobile and desktop devices. ## **Additional Tips:** - **Formatting:** You can format your signature with bold or italic text, change the font size, or add links by using the toolbar in the signature settings. - **Mobile Users:** Note that if you use the Yahoo Mail mobile app, you may need to adjust your signature settings separately on the app. The steps for mobile can vary, so be sure to check the app’s settings if needed.
