What Is HEY and What Makes It Different From Gmail, Outlook, and Apple Mail?

Updated

HEY is an email and calendar service from 37signals that rethinks the inbox around a single premise: only the people you want email from should be able to reach you. That's a different starting point from Gmail, Outlook, and Apple Mail, which accept mail from anyone and then ask you to sort, search, and filter it. If you're deciding whether to move your primary address, the practical question is whether you want a service that screens senders up front rather than one that gives you more tools to manage an open floodgate.

The core idea: screen senders, don't sort messages

Most email services assume anyone can email you, and your job is to store, sort, search, and categorize what arrives. HEY inverts that. As Ezra Klein put it in a testimonial on HEY's site, "HEY assumes that only the people you want email from should be able to email you."

That single design choice drives most of what feels different:

  • Screening happens before the inbox, not after. New senders are evaluated rather than dumped into a pile you clean later.
  • The inbox is a curated space, not a firehose you triage.
  • Privacy and time protection are treated as the default, not features you configure.

Mike Davidson framed it as: "If you designed email from scratch such that it vigorously protected your privacy and your time, this is what it would look like."

What HEY includes

HEY is both email and calendar. The site's headline is "We finally fixed your email + calendar!" and it explicitly notes "HEY has a calendar now!" So if you're comparing it to Gmail or Outlook, you're comparing a combined mail-and-calendar product, not mail alone.

The positioning is direct: "Gmail, Outlook, and Apple got complacent and took their eye off the ball. Then along came HEY." That's marketing language, but it tells you the intended audience — people who feel the big providers stopped meaningfully improving.

How it differs from Gmail, Outlook, and Apple Mail

Dimension Gmail / Outlook / Apple Mail HEY
Who can reach you Anyone, then you filter Only senders you want (screening first)
Default posture Open inbox, manage the volume Curated inbox, protect your time
Scope Mail (calendar often separate or bundled differently) Mail + calendar together
Design stance Incremental features on a long-standing model Rebuilt from scratch, per the site

The testimonials on HEY's page consistently describe it as a "rethinking" rather than an add-on. Adrian Holovaty called it "a complete rethinking of email, full of bold, brilliant ideas," and Kevin Rose described it as "a beautiful rethinking of everything wrong with email."

What to check before switching

  • Trying it costs nothing to start. HEY offers a 30-day free trial with "no obligation, no CC required." That's the lowest-risk way to test whether the screening model fits how you work.
  • Pricing is a separate page. The site links to a Pricing page, so check current plans and terms there rather than assuming a tier.
  • Migration is a real consideration. Tens of thousands of people have switched from Gmail, Yahoo Mail, Outlook, and other services, per the site — but moving a primary address is a decision about your contacts and workflows, not just the app.
  • The model is opinionated. If you rely on receiving mail from unknown senders (forms, cold outreach, signups), confirm how HEY handles those cases before committing.

Who this is for

HEY suits people who are tired of managing an open inbox and want the service to make the "should this reach me?" decision earlier. It's less suited to anyone whose work depends on unfiltered inbound mail from strangers. The clearest way to decide is to use the 30-day trial and see whether screening-first feels like relief or restriction.
