> Proprietary Clients: You cannot use your own email client to access Hey. The stated justification for this is just lazy imo. Even Gmail which launched with a then unique labels and smart organization still allows IMAP support. The Screener could very well have been a mapped IMAP folder, and you could just move to Inbox to accept new emails in. When you build on top of an open protocol and then refuse interoperability, it reeks of an old Microsoft playbook.

I’d actually flip this around—I don’t see any reason Hey couldn't and shouldn't just be an email client, which could work with any existing service.

Unless it's a strategy to lock in users. No deal for me, thanks.
