Custom Email, Organizations & Teams, Agent Chat & DataSheet

Owlu's biggest release yet: custom & self-hosted email, organizations and shared mailboxes, a conversational agent with dedicated screens, typed DataSheets, and a mail engine rebuilt on NWConnection.

  • Custom & self-hosted email: connect any custom-domain or company IMAP account via a full-screen setup wizard, with real-time IDLE delivery and Owlu-hosted mailboxes gated behind DNS domain-ownership verification
  • Organizations & Teams: redesigned member invites (production-grade emails + web landing), shared mailboxes and addresses, and Owlu-hosted organization domains
  • Agent chat: dedicated compose-confirm and find-mail screens backed by MCP tools, recommended-workflow preset cards, resumable build agents, and cross-domain unified search
  • Workflows & DataSheet: typed columns with CSV persistence, one-source → multiple-rows distribution, web-search fan-out, approval cards showing real node results, and a per-node sending-account picker
  • Attachments: large-attachment sending via OneDrive offload (Outlook) and a unified end-to-end download path
  • Mail engine: MailCore IMAP transport migrated to NWConnection (11 operations), one-click List-Unsubscribe, and UIDVALIDITY change recovery
  • Outlook: real-time Sent folder, self-send identity rotation & restore, and Graph draft server sync
  • Permissions & reconnect: a universal permission gate with a Settings grant window, plus active 'reconnect account' banners
  • Fixed crashes on new-mail receipt, account unlink, and draft restore
  • Sending: double-send idempotency guard, optimistic background send, and removal of the Gmail delete 'flicker'
  • AI summaries: fixed summaries that never arrived or stayed stuck until restart (WebSocket reconnect)
  • Calendar: remind rows now render, event start/end timezones corrected, and duplicate schedule rows removed
  • Security: raw email addresses removed from telemetry, account-deletion cascade hardening; signed, notarized & Gatekeeper-verified
