What is a Disposable Email?

A disposable email address, often referred to as DEA, is a type of service that creates unique or random email addresses for each use or entity. These email addresses are typically used only once and are not intended to receive future emails. While disposable email addresses can be used for spam, they also serve legitimate purposes. Some users employ them to protect their privacy or manage their online identities. However, for application developers, the use of disposable email addresses can lead to issues such as spam sign-ups, fraud, and reduced engagement.

Fugue Solutions Disposable Temporary Email Domain Checker API

The Disposable Temporary Email Domain Checker API by Fugue Solutions helps you block disposable email domains and secure your platform with ease. By integrating this API, you can ensure that your application interacts only with valid, resolvable email addresses, enhancing user verification and reducing spam.

Why Block Disposable Emails?

If your application allows sign-ups or interactions using disposable email addresses, it may face several challenges:

Increased Fraud: Disposable emails are often used by spammers or malicious users to create multiple accounts for fraudulent activities.
Reduced Engagement: Since disposable emails are temporary, any communication sent to these addresses may never be seen by the user, leading to ineffective communication.
Spam Prevention: Blocking disposable emails helps maintain the integrity of your user base, ensuring that only legitimate users interact with your platform.

Key Features of the API

Blocklist Verification: The API checks if a domain, or any of its subdomains, is listed in a blocklist of known disposable and malicious domains.
MX Record Validation: The API verifies if the domain has valid MX records, confirming its ability to receive emails.
Simple Integration: Easily integrate the API into your Node.js application with straightforward endpoints and reliable performance.
Real-Time Results: The API provides instant responses, allowing you to make real-time decisions during user registration or email verification processes.

Step-by-Step Guide to Integrating the API in Node.js

Step 1: Get a RapidAPI Account

To get started, you need a RapidAPI account. RapidAPI is a platform that allows you to access various APIs, including the Disposable Temporary Email Domain Checker API.

Sign up for a RapidAPI account.
Once signed in, navigate to the Disposable Temporary Email Domain Checker API.
Subscribe to the API to get your API key, which will be used to authenticate your requests.

Step 2: Set Up Your Node.js Environment

Ensure you have Node.js installed on your system. If not, you can download it from Node.js official website.

Initialize a new Node.js project:

mkdir email-checker
cd email-checker
npm init -y

Install the axios package, which will be used to make HTTP requests to the API:

npm install axios

Step 3: Create a Node.js Script to Check Email Domains

Create a file named checkEmailDomain.js in your project directory and add the following code:

const axios = require('axios');

const checkEmailDomain = async (domain) => {
    try {
        const response = await axios.get(`https://disposable-temporary-email-domain-checker.p.rapidapi.com/${domain}`, {
            headers: {
                'x-rapidapi-host': 'disposable-temporary-email-domain-checker.p.rapidapi.com',
                'x-rapidapi-key': 'YOUR_RAPIDAPI_KEY' // Replace with your actual API key
            }
        });

        const data = response.data;
        console.log(`Domain: ${data.name}`);
        console.log(`Blocked: ${data.blocked}`);
        if (data.unresolvable) {
            console.log('Unresolvable: Yes');
        } else {
            console.log('Unresolvable: No');
        }
    } catch (error) {
        console.error('Error checking domain:', error);
    }
};

// Example usage
checkEmailDomain('mailinator.com');

Replace 'YOUR_RAPIDAPI_KEY' with your actual API key obtained from RapidAPI.

Step 4: Run the Script

Execute the script using Node.js:

node checkEmailDomain.js

Example Outputs

When the domain is not blocked:

Domain: gmail.com
Blocked: false
Unresolvable: No

When the domain is blocked:

Domain: mailinator.com
Blocked: true
Unresolvable: No

When the domain is unresolvable:

Domain: gmail.con
Blocked: false
Unresolvable: Yes

Use Cases

Email Verification: Integrate this API into your sign-up process to ensure users provide valid, non-disposable email addresses.
Spam Prevention: Prevent bots or malicious users from signing up with disposable emails often used in spam or fraudulent activities.
Email Campaigns: Ensure your email marketing campaigns are sent to legitimate, resolvable domains to increase effectiveness and engagement.

API Overview

The Disposable Temporary Email Domain Checker API allows you to determine whether a given domain should be blocked based on a continuously updated blocklist of known disposable, temporary, DDNS, and malicious email domains. It also checks if the domain is resolvable by verifying the presence of MX (Mail Exchange) records.

Blocklist Verification: Identify whether a domain, or any of its subdomains, is listed in an extensive blocklist of known disposable email providers.
MX Record Validation: Confirm that a domain can receive emails by checking for valid MX records.

Simple Integration and Free Plan

The API offers a generous free plan for small projects, making it easy to start filtering domains with minimal setup. For more details, visit Fugue Solutions.
