About HEY

HEY is an email service from 37signals, the company behind Basecamp. It rethinks the inbox with sender screening, in which people you have not approved cannot land in the main inbox, and with bundles that group types of mail together, so users deal with email on their own terms.

The vendor frames HEY as a privacy-respecting alternative to the large email providers and has also released a calendar app, a service for using HEY with custom domains, and tools for AI agents and a command-line interface. It is a hosted service, so there is nothing to self-host.

HEY is sold on subscription, with a 30-day free trial that needs no credit card, and the plans are on the pricing page. It suits individuals and small teams willing to switch from Gmail, Outlook or other providers to a different way of handling email.
