Best for
  • Workflows where AI agents need their own email inbox for autonomous operation.
  • Automated email handling without human intervention, especially with Claude, Codex, Cursor, etc.
  • Developers who prefer standard protocols (JMAP) to avoid vendor lock-in.
  • Developers using Hostinger services.
  • Users who want to automate hosting tasks through AI assistants.
Not for
  • Scenarios requiring human review of every email, since agents can autonomously send and receive.
  • Mission-critical email for enterprises that cannot rely on third-party deliverability guarantees.
  • Organizations that need full control over their email infrastructure or offline operation.
  • Users not on Hostinger.
  • Those needing to manage other cloud providers.
Required permissions
  • Read and write local credential files (default at `~/.atomicmail/credentials.json`).
  • Network access: communicate with Atomic Mail's auth service and JMAP API.
  • Environment variables: may require `ATOMIC_MAIL_API_KEY` to skip registration.
  • Requires a Hostinger API token or OAuth authorization.
  • Can read and modify domains, hosting resources, etc., depending on token scopes.
Risks and side effects
  • API keys stored locally could be misused if leaked.
  • Email content is untrusted; agents might be tricked into executing malicious instructions (e.g., phishing).
  • Service is in alpha with storage quotas and rate limits; may be unstable.
  • Dependency on external service; if Atomic Mail is down, agent email functionality is affected.
  • High-risk operations (e.g., deleting websites) are irreversible.
  • API token leakage could allow misuse of resources.
  • Mistakes could cause website or service outages.
