Superhuman Engineering with Emuye Reynolds

Email has become such a routine feature of knowledge work that we often take it- and the email clients we use for it- for granted. While advancements such as intelligent spam filtering have improved the experience, many email clients retain the same basic structure and offer a largely similar experience.

Superhuman is building a modern email client meant to reimagine email from the ground up. Superhuman is built to be fast, and seamlessly integrates insights from social networks such as Linkedin. It offers features such as undo send, AI triage, and mail status tracking. Superhuman even works offline, using Service Workers to serve cached assets when a network connection is not available. 

Emuye Reynolds is the Head of Engineering at Superhuman. She was formerly a Senior Software Developer at Apple and led the development of the UI for Apple TV UI. She joins the show today to talk about what’s lacking from traditional email clients, what engineering challenges her team faces when building across multiple platforms, and how Superhuman’s new features represent an evolutionary step forward for email client technology.
