Opinionated email service from 37signals with a sender screener
HEY is a paid email service from 37signals, the makers of Basecamp, that rethinks how mail is triaged. First-time senders must be approved in the Screener, newsletters go to The Feed, receipts to the Paper Trail, and spy pixels are blocked automatically. It includes a calendar and supports custom domains for businesses, but works only with HEY addresses rather than existing Gmail or IMAP accounts.
