HEY UI design & app screens

HEY is Basecamp's opinionated email service that rethinks the inbox with screening, bundling, and a focus on intentional communication. It targets people frustrated with traditional email.

The design is distinctive and confident: the Imbox, Feed, and Paper Trail concepts reorganize mail entirely, with bold typography, generous spacing, and playful copy. Workflows like screening new senders are surfaced as first-class, opinionated interactions rather than buried settings.
