API at a Glance

ResourceWhat You Can Do
SeedsList, retrieve, and manage seed email addresses. Trigger shuffles (in-place, by provider, or custom) and check cooldown status.
SendersCreate and configure sender profiles with domain, tag, and engagement presets (warmup, repair, boost, protect, or custom rules).
BroadcastsPull placement data for every send — primary, promotions, and spam breakdown by provider (Gmail, Yahoo, Outlook, and more).

Quick Start

Authenticate with your API key and start managing seeds in seconds.

# List your seed email addresses
curl -X GET "https://api.inboxally.com/v3/seeds" \
  -H "X-API-KEY: your-api-key" \
  -H "Accept: application/json"

Response:

{
  "data": [
    {"email": "seed-0041@inboxally.net", "provider": "gmail", "status": "active"},
    {"email": "seed-0042@inboxally.net", "provider": "outlook", "status": "active"},
    {"email": "seed-0043@inboxally.net", "provider": "yahoo", "status": "active"}
  ],
  "next_page_token": "eyJsYXN0X2lkIjo0M30"
}

Add these addresses to your ESP as contacts, include them in your sends, and InboxAlly handles the rest.

Authentication

All API requests use the X-API-KEY header. Generate your key from My Account → API in the InboxAlly dashboard and include it in every request. Keys are account-scoped — keep them server-side and never expose them in client code.

What You Can Build

The API gives you the building blocks to embed deliverability into any product or workflow. Here are some examples:

Automated onboarding — When a new client signs up for your platform, use the Senders endpoint to create a sender profile and the Seeds endpoint to pull seed addresses. Import seeds into the client’s ESP automatically, so deliverability improvement starts from day one.

Placement monitoring dashboard — Use the Broadcasts endpoint after every send to pull inbox placement data broken down by provider. Display Gmail, Outlook, and Yahoo placement rates inside your own product — no need to build placement detection from scratch.

Multi-client management — Agencies can use the API to manage seeds and senders across dozens of client accounts from a single script. Rotate seed lists, trigger shuffles, and pull placement reports for every client without logging into the InboxAlly dashboard.

CI/CD pipeline integration — DevOps teams can add deliverability checks to their deployment pipeline. After pushing a new email template, automatically trigger a broadcast and check placement results before scaling the send.

Who Uses the API

  • Email service providers adding deliverability features
  • Agencies managing multiple client accounts
