Everything you need to build with email
IMAP Sync
Real-time mailbox synchronization with incremental sync, thread reconstruction, and full-text search.
Send & Reply
Compose, reply, and manage drafts through a clean API. Attachments, HTML, and plain text supported.
Multi-Provider
Gmail, Outlook, Yahoo, iCloud — connect any provider with built-in presets or custom IMAP/SMTP settings.
Credential Protection
OAuth and password credentials stay on the server. API tokens with scoped permissions ensure LLMs never see raw credentials.
MCP Server
First-class Model Context Protocol support. Let AI agents read, send, and manage email through standard MCP tools.
CLI & API Tokens
Full-featured CLI for automation and scripting. Scoped API tokens with granular per-account, per-action permissions.
