What DeoMail is
DeoMail provides custom-domain email hosting through a webmail inbox, with forwarding, automation, message controls, AI assistance, and an API. Incoming mail can be routed to Gmail or Outlook. Fire automations can trigger webhooks, Slack messages, or HTTP requests when matching rules are met, with listed integrations including Discord, Telegram, Sheets, Twilio, Zapier, n8n, and Make. Fade messages can expire or be revoked, with optional passwords and view limits. Fingerprint adds cryptographic verification and a QR code for checking whether a message changed. Flow classifies mail, summarizes threads, and drafts replies using an LLM, either through managed AI or your own key. The REST API handles sending, reading, and managing email with scoped permissions. DeoMail states that mail is encrypted in transit and storage under a zero-access policy, and lists TOTP two-factor authentication, PIN lock, login alerts, session management, and trusted devices. The free plan includes one mailbox, one custom domain, 500 MB storage, unlimited incoming mail, and 100 outgoing messages per day. IMAP is supported.
