Native mail integrations

Connect the mailbox you already have.

Use Google Workspace through tenant-owned Google OAuth or keyless service-account domain-wide delegation, Outlook.com and Microsoft 365 through Microsoft OAuth, Fastmail through JMAP, Helpmonks through its native API, or any standard IMAP mailbox with SMTP for sending. MCP-compatible clients connect over OAuth for mail search, triage, summaries, draft suggestions, routing, and approval review.
