    Note: If you're using Gmail on the desktop, you might need close the Gmail tab/window and open it again otherwise the newly installed add-on will not appear.

    On the web version of Gmail, add-ons appear on the right side of the screen. Click on the shopping cart icon to open the add-on.

  6. A new window will open that asks you to login to your Google account on merchantmail.app. It may seem odd to have to login in a second time, but this is required for maximum security. Click on the name of your Google account to proceed.

  7. All done!

    At this point, you should be able to start using the add-on. The image below shows a properly configured add-on. If the Gmail Add-on still shows the message asking you to sign into Google account on merchantmail.app, try looking at a different email or restarting Gmail.
