The native macOS email client built for autonomous agents. DarkMail gives AI assistants structured, permission-aware access to email while keeping humans in control. Built natively for macOS with speed, privacy, and automation at its core.
Traditional email clients were designed for people. DarkMail was designed for AI systems that need structured access to conversations, attachments, metadata, permissions, and workflows.
Interface matters. Infrastructure changes everything.
This is the email layer for autonomous software.
Every AI assistant gets its own mailbox. Separate identities. Separate permissions. Separate history.
Give an agent exactly what it needs. No more.
DarkMail understands threads. Your AI receives the entire conversation — not disconnected messages.
Every message becomes structured data: sender, recipients, intent, attachments, metadata, priority, entities.
AI drafts. You approve. One click.
Runs natively on macOS. No Electron. Fast. Private. Yours.
Email arrives in your inbox.
Structures and understands the message.
Analyzes context and determines intent.
Agent creates drafts, tasks, or updates systems.
You review and approve when needed.
Message sent with full context and confidence.
Markus needed a way to interact with email like an operating system — not like a person.
DarkMail became the communication layer between AI agents and the outside world.
Now every message can become work.
let emails = try await darkmail.inbox(.salesAgent)
let urgent = emails
.filter { $0.priority == .high }
.withAttachments()
let result = try await markus.reply(
to: urgent,
using: salesAgent,
approval: .required
)
Built with modern macOS technologies for speed, reliability, and efficiency.
Your data is yours. Always.
DarkMail ships the way underground software always did — no app store, no cloud dashboard, no managed service. One disc image. Your machine. Your rules.
Download the DMG installer, drag it into Applications, and own your email infrastructure. No accounts, no telemetry, no middlemen.
Email hasn't fundamentally changed in decades. Humans still manually classify, summarize, draft, and respond to thousands of repetitive messages.
AI changes the interface.
DarkMail transforms email into structured tasks that autonomous assistants can understand, reason about, and execute — while keeping the user in complete control.
DarkMail can run alongside or replace Apple Mail. It connects to the same IMAP/SMTP accounts but adds AI agent capabilities on top.
Yes. DarkMail works with any IMAP/SMTP provider including Gmail, Outlook, Fastmail, Proton, and custom domains.
Only if you enable Autopilot mode. By default, all AI-drafted messages go through the human approval queue first.
Yes. DarkMail caches everything locally. You can read, search, and draft offline. Sync happens when you reconnect.
The core engine is open source on GitHub. The Pro and Enterprise features are commercial.
