Embed Email Health Checks

Add a free email authentication health widget to your product, control panel, or documentation. Your customers see SPF, DKIM, DMARC, and MX status at a glance — zero engineering on your side.

Zero engineering

Drop in a single iframe tag. We handle the DNS queries, analysis, and rendering.

Reduce support tickets

Customers self-diagnose email issues before contacting you. "Check your email health" becomes a one-click action.

Competitive differentiation

Show customers you care about email deliverability. Health checks build trust.

White-label ready

Dark and light themes. Summary or compact mode. Fits any product design without custom styling.

Live Preview

Enter any domain to see the widget in action. Add DKIM selectors for a complete check.

Get the Embed Code

Copy this snippet into your HTML. Replace YOUR_DOMAIN with the customer's domain and YOUR_TOKEN with your partner embed token.

<iframe
  src="https://tools.mxio.io/embed/health?domain=YOUR_DOMAIN&token=YOUR_TOKEN&mode=summary&theme=dark"
  width="100%"
  height="320"
  style="border:none"
  title="Email Health Check"
></iframe>

Anonymous embeds (no token) work immediately at 10 requests/min. Partner tokens get 30-60 req/min depending on review status.

Parameters

Param	Required	Description
`domain`	Yes	Domain to check (e.g. `example.com`)
`token`	No	Partner embed token for higher rate limits and attribution
`selectors`	No	Comma-separated DKIM selectors to check (max 5, e.g. `google,selector1`)
`mode`	No	`summary` (default) or `compact`
`theme`	No	`dark` (default) or `light`

JSON API

Need raw data instead of an iframe? Use the JSON endpoint with your API key.

curl -H "Authorization: Bearer YOUR_API_KEY" \
  "https://tools.mxio.io/api/tools/embed/health?domain=example.com&selectors=google,selector1"

Returns a JSON response with overall_status, individual check results (SPF, DKIM, DMARC, MX), and areport_url linking to the full report. JSON API users must display “Powered by mxio.io” attribution with a link back to mxio.io.
