A privacy email provider is building email for AI agents, with JMAP, PoW signups and 2,000 accounts

A privacy email provider says it has built email specifically for AI agents, not for humans managing inboxes.
- It uses JMAP because models can already write it without reading docs, and it avoids vendor lock-in.
- Signup uses proof-of-work plus reputation scoring instead of CAPTCHA to slow mass account creation and quarantine spam.
- The team split large emails by sending headers through Kafka and bodies through object storage, then reassembling them on the consumer side.
- The site serves humans a normal landing page, while non-browser agent requests get plaintext setup instructions, including MCP or Skill install commands.
- E2EE is still on the roadmap because agents need plaintext to act on messages.
- The team says it has around 2,000 accounts and is growing by 10–30 a day.
