Three ways to connect

Connector, webhook or raw REST: one permissions model

Native connectors for the tools you already run, signed webhooks for anything event-driven, and the REST API that both of them sit on.

Native connectors

Sequencers, CRMs and warmup networks connect over scoped OAuth: no code to write, and revocable from your workspace at any time.

Signed webhooks

Six fleet events post to your endpoint as they happen, signed so you can verify the sender. Nothing sits on a timer.

REST underneath all of it

Every action the console can take is an HTTP endpoint, authenticated with one key you can rotate whenever you want.

Build your own

No connector yet? It is one REST call away

Every action the console can take is a documented endpoint: buy a domain, generate a mailbox roster, subscribe to fleet events.

bash: provision a mailbox
# create a mailbox on an existing domain
curl https://api.infrabox.software/v1/mailboxes \
  -H "Authorization: Bearer $INFRABOX_KEY" \
  -H "Content-Type: application/json" \
  -d '{"domain":"sendwith.io","local_part":"mia","warmup":"standard"}'
webhook: mailbox.provisioned
{
  "event": "mailbox.provisioned",
  "created_at": "2026-08-27T14:02:11Z",
  "data": {
    "mailbox_id": "mbx_7f2ad91c",
    "domain": "sendwith.io",
    "address": "[email protected]",
    "warmup_status": "scheduled"
  }
}

Six events cover the whole fleet

Subscribe once and every change arrives as a signed POST. Nothing in your pipeline has to poll.

  • domain.verified

    DNS verification finishes for a sending domain.

  • mailbox.provisioned

    A mailbox is created and cleared to send.

  • warmup.completed

    A mailbox reaches the end of its ramp curve.

  • deliverability.alert

    Placement or reputation crosses a threshold you set.

  • message.bounced

    A send returns a hard or soft bounce code.

  • domain.blocklisted

    A monitored blocklist starts listing one of your domains.

How it connects

A connection is three steps and one scope

Access is narrowed at the moment you grant it, and revocable the second you change your mind.

  1. Step 1: Pick the tool

    Choose a connector from the directory, or generate an API key if you're building your own.

  2. Step 2: Grant a scope, once

    Hand it domains, mailboxes or events only, never the whole workspace, and never a password.

  3. Step 3: It syncs until you revoke it

    Sends, replies and health events move in both directions, and access ends the second you pull the key.
