I paid $30 per month for email. Superhuman vs HEY. One was worth it. Spending significant money on an email client sounds crazy to people who use default free Gmail. But if you process fifty to one hundred client messages daily, email is your primary workstation. I used both Superhuman and HEY for six months each to see which philosophy actually delivers inbox sanity.
Superhuman is built for speed and keyboard shortcuts, while HEY from 37signals was built to protect your attention through strict consent-based screening.

1. Working with Existing Accounts vs Full Migration
In my hands-on testing of superhuman vs hey, the results confirmed clear performance distinctions. The biggest hurdle with HEY is that you must change your email address to @hey.com or configure complex domain forwarding. For established business owners with years of contacts, that migration is a massive headache.
When evaluating superhuman vs hey for day-to-day work, usability is just as critical as raw features. Superhuman connects directly to your existing Google Workspace or Microsoft Outlook account in thirty seconds. All your existing labels, archives, and contacts remain untouched.
