Introduction

Overview

The Check-Mail.org API is an easy and robust API designed to help developers validate email addresses and domains efficiently. Its primary purpose is to prevent fraud and abuse, and enhance data quality.

Key Features

  • Block Disposable Domains: Prevent sign-ups with temporary email addresses.
  • Detect Invalid Emails: Ensure email addresses are syntactically correct.
  • Advanced Heuristics: We use multiple advanced heuristic methods to detect and block both invalid, and disposable temp emails in real-time.
  • Risk Score Assessment: Receive a risk score (1-100) based on multiple live-updated factors.
  • Domain-Only Submissions: You can submit just the domain to limit processing of personal data, for example for GDPR compliance.

Use Cases

  • Fraud Prevention: Block fake or malicious accounts.
  • Email Marketing: Improve deliverability and engagement rates.
  • Security Enhancement: Identify high-risk users using the risk score.

How It Works

The basic workflow is really simple:

  1. Submit an Email or Domain: Send a full email address or just the domain, with a simple HTTP GET request.
  2. Receive a Response: Get a JSON response with fields like block, valid, disposable, and risk.
  3. Interpret the Data: Use the response to make informed decisions in your application.
