Hey

37signals

The opinionated inbox that screens strangers: Imbox, Feed, Paper Trail — Superhuman's opposite, now with Hey World and a refusal to become a chatbot.

Product preview

Overview

Hey is the inbox that treats AI as optional and strangers as the problem: you screen once, the Feed is not the Imbox, newsletters do not steal the morning. Superhuman is speed; Shortwave is Gmail-plus-AI; Hey is a religion.

You will migrate. Your company may refuse. For personal mail that was drowning, it is still the product that changed the shape. For a Workspace tenant, it is a side account.

Pros / Cons

Pros

Strangers never hit the Imbox twice
Newsletters live in the Feed, not the morning
Paid, no ads, 37signals opinions
Still the shape-changing personal inbox

Cons

Migration, and work mail may refuse
Not an AI-draft inbox
A religion, not a Workspace default

Who it's for
