Overview
Mailsac lets you create disposable email addresses and read incoming messages via API — ideal for testing email-sending features in your app. You can check any @mailsac.com inbox without creating an account first. Use an API key for higher rate limits and private inboxes.
Beginner Tip
Public @mailsac.com inboxes are readable by anyone who knows the address, so never use them for sensitive data. For private inboxes, use a paid plan and set a custom address.
Available Data
The kind of data this API exposes, based on its documentation. We could not call the endpoint to confirm the exact field names.
Example Response
Illustrative shape only — we were not able to call this endpoint (it requires credentials or exposes no public sample URL), so the fields below show the kind of data this API returns rather than a recorded response.
{
"message_id": "msg_abc123def456",
"status": "delivered",
"to": "[email protected]",
"subject": "Welcome!",
"timestamp": "2025-01-15T10:30:00Z"
} Field Reference

Calls a real endpoint of this API. Replace any placeholder credentials with your own key.
const url = "https://mailsac.com/api/addresses/[email protected]/messages"; // Replace headers or query params with the values required by this API. const response = await fetch(url, { headers: { "X-API-Key": "YOUR_API_KEY" } }); if (!response.ok) throw new Error(`Request failed: ${response.status}`); const data = await response.json(); console.log(data);
