What DeoMail is
DeoMail is a web-based email host for custom domains, with a modern inbox and tools for managing incoming and outgoing messages. Incoming mail can be forwarded to an external address such as Gmail or Outlook. Fire runs actions when incoming emails match rules, including webhooks, Slack messages, and HTTP requests; its listed integrations include Slack, Discord, Telegram, Sheets, Twilio, Zapier, n8n, and Make, along with webhook-compatible tools. Fade lets users set messages to expire or revoke them, with optional passwords and view limits. Fingerprint provides cryptographic email verification and a QR code recipients can use to check whether a message was changed. Flow classifies incoming mail, summarizes threads, and drafts replies with an LLM, using either managed AI or a key supplied by the user. A REST API supports sending, reading, and managing email, with scoped API-key permissions. DeoMail states that email is protected with TLS in transit, encrypted storage, and a zero-access policy. It also 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 of storage, unlimited incoming mail, API access, one Fix per day, and a 100-message daily sending limit. IMAP is supported.
