Application Design

User Interface

This application has a user interface that executes in the chrome extension popup window. The popup window is easy to access but also places limitations on the maximum size of each view.

There are currently 2 main views: inbox and message.


inbox displays a list of received messages; this is the default view that is displayed to user.

displays current address
button to copy current address
button to request new address
button linking to more apps


Empty states

There are two possible scenarios where no list of messages will render: when mailbox is empty or when mail server is unavailable.

When mailbox is empty, inbox view should, in the place of list of messages, render a message stating there are no messages.

When mail server is unavailable, current address and button to request new address should be disabled or unavailable since these rely on mail server availability. In addition, message should be displayed to user to explain why connection is failing and certain features are currently unavailabile.


message displays the contents of a single message. User cannot navigate to this view directly. Instead user must choose a message from inbox view, which then redirects user to message view.

Blocking images

With HTML emails any images are initially blocked until user explicitly requests for them to be shown by clicking a button. Once images are displayed, on subsequent views of the same message, the images will be rendered normally.
