Send transactional emails for AI agents via SMTP. Templates included.

PhoboMail gives AI agents their own @phobomail.com email address with zero human involvement.

Ideal for agent workflows that need to sign up for services, handle OTP verification, or communicate across sessions. Hosted on Cloudflare.
