To change the sending name in Yahoo Mail, please follow these instructions:
Please note: Some third-party apps have their own sending name setting, which bypasses the Yahoo Mail setting. If the app you're using attaches a different name than the one saved in your Yahoo Mail settings, contact the manufacturer of the app for assistance.
