Mail by develate
Get started
Mailbox infrastructure built for AI agents

Let agents use email. Keep control.

Mail by develate sits between AI agents and real mailboxes. Agents get only permissions you grant—never mailbox or SMTP credentials.

One policy

Same safety rules across every interface.

Zero shared secrets

Agents never receive IMAP or SMTP credentials.

Every action recorded

Allowed, denied, confirmed, and executed.

How it works

A checkpoint for every mailbox action.

Your agent asks. Mail by develate decides what happens next—using grants, policies, quotas, and confirmation rules you control.

  1. 01

    Agent submits an action

    Search, read status, or send through REST or MCP.

  2. 02

    Control plane evaluates it

    Grant ancestry, policy, target, and quota checked together.

  3. 03

    Safe outcome, fully recorded

    Execute, deny, or pause for human confirmation—with audit proof.

Safety by design

Useful autonomy without blind trust.

Safety is part of execution path—not a prompt your agent can ignore.

Scoped grants

Give each agent only actions, mailboxes, and targets it needs. Revoke anytime.

Human checkpoints

Require approval for sensitive actions before anything reaches your mail server.

Hierarchical quotas

Cap activity across parent and child grants. Delegation never expands authority.

Tamper-evident audit

Append-only, hash-chained events show who requested, approved, and executed what.

Connect your way

One control panel. Three ways in.

REST, MCP, and dashboard share same policies, confirmations, quotas, and audit history.

REST API MCP server Web dashboard
POST /api/v1/actions 202 ACCEPTED 
{
  "action": "mail.send",
  "mailbox": "support",
  "payload": {
    "to": "customer@example.com"
  }
}
Pending confirmation

Every request receives an opaque action ID.

Ready when your agents are

Put your inbox behind a proper control panel.

Connect a mailbox, define agent permissions, and keep every action visible.
