For our first version, we are more driving this email product to a chatting product. So we don’t provide options for “Reply” and “Forward”.
Let me demonstrate the process from the very beginning.
As you can see from the picture below, our first version is pretty similar with FB Messenger. The reply area seems that it does not belong to the 20/80 principle. We had some discuss whether we should show all the options or only the most frequently used options. But for efficiently sending messages (pictures, voice, emojis), we decided to show them all for now. We will collect the data for user behaviors. Then we will improve the design from there.
A clearer user interface that helps users switch to "Reply" and "Forward".
