Connect AI email agents to your CI/CD system, alerting stack, and incident workflows. Programmable, observable, and resilient — without sacrificing operational control.
Generic mail APIs were designed for transactional messages, not operational workflows. They lack observable send queues, have no concept of agent-safe permissions, and give DevOps teams no way to distinguish a human-composed email from one generated by an automated agent. When a deployment fails at 2am and your incident response pipeline needs to notify stakeholders, route escalations, and log everything to your audit trail, you need infrastructure that behaves like infrastructure — not a marketing email service bolted onto a REST endpoint.
MultiMail provides a REST API and MCP server purpose-built for agents operating in production pipelines. Every send goes through an observable queue you can inspect and cancel. Every action produces a structured audit event. The monitored oversight mode is a natural fit for DevOps: agents send autonomously, but every delivery is visible to your team in real time. You can hook MultiMail into a Cloudflare Worker, a GitHub Actions step, or an existing alerting stack without changing your queue or on-call tooling.
A deployment completion, failed health check, or PagerDuty escalation fires a webhook or queue message. Your agent receives the event payload — build SHA, environment, affected services, timing data — and begins composing context.
The agent calls your monitoring APIs to gather incident links, rollout timing, and health check results, then drafts a structured summary. No template required — the agent produces the message body from live data.
For routine deploy summaries, the agent posts to a monitored mailbox (POST /v1/mailboxes/{mailbox_id}/send) and the message goes out immediately. For high-severity incidents, route through a gated_send mailbox so a human approves before delivery to stakeholders outside your org. Oversight mode is a property of the mailbox, not a per-send field.
Every send produces a delivery event you can consume via webhook or poll with GET /v1/mailboxes/{mailbox_id}/emails. GET /v1/oversight/pending shows any messages still awaiting approval. POST /v1/mailboxes/{mailbox_id}/emails/{email_id}/cancel lets you pull a queued send before delivery if the incident resolves.
MultiMail logs every agent action — who sent, what oversight mode was active, delivery status, and any approval events — giving you a complete record for postmortems and compliance reviews.
Pick your platform, copy the prompt, and paste it to your AI agent — it sets up MultiMail and builds the whole flow. Nothing to fill in.
Every outbound message held under a gated mode enters a queue you can inspect with GET /v1/oversight/pending and cancel with POST /v1/mailboxes/{mailbox_id}/emails/{email_id}/cancel. If an incident resolves before your notification sends, you can pull the message. Generic SMTP relays offer no equivalent.
Configure monitored mode for routine deploy summaries and gated_send for P0 escalations — in the same pipeline, using the same API. No separate tool for 'high-trust' vs 'low-trust' sends.
Every agent action produces a timestamped audit event: who sent, which oversight mode was active, whether approval was required, and delivery status. Feeds directly into postmortems and SOC 2 evidence collection.
MultiMail's API runs on Cloudflare's global network. If you deploy your incident-response logic in Cloudflare Workers, your email calls stay on-network with sub-5ms routing latency in most regions.
Receive alert emails from external monitoring systems into a dedicated MultiMail mailbox and route them into PagerDuty, Slack, or your own queue via webhook. GET /v1/mailboxes/{mailbox_id}/emails and GET /v1/mailboxes/{mailbox_id}/emails/{email_id} let agents poll and triage inbound ops mail programmatically.
