Imitate Email Chrome Extension
The Chrome Extension (and Firefox Extension) make it even easier though. Simply install the extension and it will put the embeddable email viewer in to every localhost tab by default.
No need to add anything to your front end. Just send emails to Imitate Email and they'll appear in your app.
Visit our Chrome extension in the Google Web Store by clicking this button and install the extension.
The extension will automatically enable the embeddable email viewer on all localhost tabs.
Enabling the viewer (non localhost)
To enable the viewer on non-localhost tabs you will need to enable that particular host from the extension settings. Simply click the extension button from the Chrome address bar and toggle to enabled.
