Why it lasted

  • It is the only identity layer the internet agreed on.
  • Every 'email killer' became another inbox that still forwards to email.
  • SMTP is ugly, federated, and older than the web. That is the moat.

Times it almost ended

  • Lotus Notes, Exchange-as-the-world, Wave, Inbox, Slack, ChatGPT: all tried to be the new email. Email kept the receipt.

What would finish it

  • A universal identity that is not an address. Phone numbers tried. They became 2FA for email.
