I have used Gmail for several years and find it to be very well designed. Email is mundane and can also be stressful, particularly because of the inbox clutter produced by having multiple emails from various different sources. A well-designed email platform faces a daunting challenge in trying to streamline this amalgamation of information. Gmail does a great job of this – firstly, its three default filters on the main page (Primary, Social, Promotions), make all these categories very easily accessible while reducing the clutter in a meaningful way. For example, while scrolling through the primary tab, I probably want to focus on work-related emails and not be distracted by promotional emails, which Gmail recognizes and handles well. There are a lot of ways in which it allows you to absorb a good amount of information with a quick glance, thus reducing the number of cognitive cycles needed to process email efficiently – (1) the relatively new feature where attachment icons are displayed in the main inbox so that you can see the names and types of attachments without having to open the email (for a sufficiently low number of attachments); (2) easy tagging mechanisms with different colors so that you can make certain emails stand out; (3) nudge feature, in which Gmail automatically resurfaces an email you sent out a few days ago but did not receive a response on. It does a good job of algorithmically determining which emails would be relevant for this category; (4) minor but neat aesthetic feature – ability to set your own background theme, which can spark a bit of joy before delving into what tends to be a rather routine activity.
