If you are a WhatsApp user, then you must know how to change email in the app. This is because if you do not have an email address set up in the app, then your messages will not be sent to the right people. To change your email address in WhatsApp, first open the app and sign in. Then, go to Settings and select Email. Under Email settings, you will need to set a new email address. Once you have set up your new email address, make sure that you are signed out of WhatsApp and then re-enter it into the app. Now that you have changed your email address in WhatsApp, all of your messages will be sent to the correct people!
