What to Do When Receiving a Self-Destructing Email on Other Providers What happens when you're using a different email provider, and you receive a self-destructing message from someone on Gmail? The answer is pretty simple; you don't actually get the message. Instead, you'll find a link to the message in your inbox. Check out the steps below to see how it works. Instructions below are for Yahoo, but the process should be similar on other email services like Outlook and Apple Mail. When you first open your inbox and see a confidential (self-destructing) message from Gmail, it'll look exactly like a normal message. Open it like you normally would. You'll notice you won't actually see the message. Instead, you'll see a note from Google saying this is a confidential message and telling you who sent it. It'll then have a link to let you access the message. Select View the email. A new tab will open, or your browser app will open on mobile. In the new tab, you'll see a message letting you know which email address the message was sent to. If you own the address, you can request the code needed to open it. Select Send Passcode to get the code. Back in your inbox, wait for a new message from Google, then open it to find the passcode for your message. Copy or memorize the code, then return to the message tab in your browser to enter the code. With the code entered, the browser tab will log you in and display the message for you. When you're done, select Sign Out.
