HEY is a from-scratch email service built by 37signals (the makers of Basecamp) around the idea that email should work the way you want, not the way senders want. The Screener requires approval before a new sender can reach you, the Imbox holds mail from people and services you care about, Paper Trail files away receipts and confirmations, and the Feed turns newsletters into a browsable, non-intrusive stream. HEY includes an integrated calendar, blocks tracking pixels used by marketers to spy on when and where you open email, and offers HEY World for publishing a personal blog straight from your inbox. It's available as a personal @hey.com account, a family plan, or HEY for Domains for teams who want the same experience on their own custom domain.
Posteo is an independent, Berlin-based email service that runs entirely on green energy and never displays ads or tracks users. It bundles email with calendar, address book, and notes functionality, and lets people sign up anonymously without providing personal information.
