Features
Email infrastructure your agents can actually use
Inboxes, threads, search, and signed events behind one API — plus autonomous deliverability controls engineered for scale.
Get an inbox
How do agents get an inbox?
Give every agent an address of its own, then manage them like infrastructure.
Get an inbox
Inboxes by API
Create dedicated sending and receiving addresses instantly via SDK, REST API, or native MCP tools. One address per agent, persona, or campaign.
Get an inbox
Shared or custom domains
Start on @try.gork.email, then move agents onto a domain you verified. Each inbox can send from its own domain.
Get an inbox
One key per agent
Scoped keys restrict agents to designated inboxes. Rotate or revoke credentials with zero impact on the rest of your fleet.
Get an inbox
Send as your team, not ours
Move agents onto a domain you verified — Gork generates the SPF, DKIM, and DMARC records and watches DNS until they resolve. Your mail carries your reputation.
Work the thread
How does it handle replies?
The full loop over one API, with threads that stay intact.
Work the thread
Deliberate outbound
Send plain text or HTML, with attachments up to 10MB, an idempotency key for safe retries, and optional scheduling up to 30 days out.
Work the thread
Threads with real history
Retrieve entire conversation threads in chronological order. Automatic In-Reply-To and References headers guarantee clean threading across Gmail and Outlook.
Work the thread
Search and recall
Fast full-text search across subject, body, sender, and recipients with multi-attribute filtering by inbox, thread, and date range.
Work the thread
Attachments and drafts
Read incoming files, fetch bytes on demand, and compose in stages: drafts consume no send quota and leave the mailbox only when dispatched.
Connect your runtime
How does it connect to your stack?
Wire the mailbox into whatever your agent already runs on.
Connect your runtime
HMAC-Signed Webhooks
email.received, email.sent, email.bounced, email.complained, and email.unsubscribed — each HMAC-signed with SHA-256 for cryptographic verification.
Connect your runtime
Never miss a reply
Failed deliveries retry automatically with exponential backoff and every attempt is recorded in delivery logs so threads never stall.
Connect your runtime
Native MCP server
Run gork-mcp inside Claude Code, Cursor, or any MCP client. Your agent gets inboxes, mail, threads, search, sends, replies, and drafts as tools.
Connect your runtime
Works with any harness
REST, TypeScript SDK, Python package, MCP, or cURL. The email layer does not depend on which model or framework you picked.
Autonomous Reliability
How is deliverability protected?
Production safeguards and sender controls enforced server-side for autonomous workflows.
Autonomous Reliability
Quotas & Runaway Protection
Daily ceilings on free workspaces, monthly quotas and spend caps on paid, and a tripwire that pauses sending after a burst of unique recipients — so an accidental loop cannot burn your sender reputation.
Autonomous Reliability
Automatic Suppression Lists
Bounces and complaints are recorded server-side from provider events. Outbound sends to suppressed addresses are rejected before delivery is attempted, with zero custom tracking code.
Autonomous Reliability
Authenticated Sending
Every send is signed with DKIM and authorized by SPF and DMARC on your domain, and always ships a plain-text alternative alongside the HTML body.
Autonomous Reliability
Real-Time Reputation Monitoring
Server-side reputation thresholds monitor bounce and complaint trends continuously, protecting your verified domain standing 24/7.
Autonomous Reliability
Predictable Budget Controls
Configure explicit per-cycle spend ceilings. Workloads halt gracefully at defined limits without unexpected billing overages.
Autonomous Reliability
Persistent Storage & Retention
Emails and attachments remain securely archived and indexed for retrieval across all plans: from 1 GB on Free to 100 GB on Scale.
Two inboxes, every capability included
The free tier includes the full REST API, webhooks, MCP tools, and 1,000 emails a month.
