Overview

Disify is a free, no-auth API that checks whether an email address or domain belongs to a known disposable or temporary email service. It helps protect sign-up forms and contact forms from throwaway addresses with a simple GET request. No API key is required, making it the fastest way to add disposable email detection to your app.

💡

Beginner Tip

You can check an email in one GET request with no setup at all — just replace the email in the URL path and you get a JSON response instantly. Cache results for the same domain to avoid redundant requests, since disposable domain status rarely changes.

Available Data

email delivery status
message ID
bounce/complaint data
open/click tracking

Example Response

JSON Response 
{
  "message_id": "msg_abc123def456",
  "status": "delivered",
  "to": "[email protected]",
  "subject": "Welcome!",
  "timestamp": "2025-01-15T10:30:00Z"
}

Field Reference

format Whether the email address has a valid format
dns Whether the email domain has a valid DNS record
disposable Whether the email domain is a known disposable or temporary email provider
alias Whether the address appears to be an alias or forwarding address
domain The domain portion extracted from the email address

Implementation Example 

const url = "https://www.disify.com/";
const response = await fetch(url);
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);
