## Overview

The Email Verification API helps businesses catch invalid, dummy, and mistyped email addresses before they enter your system. It checks whether the email domain is real and can receive messages, and returns domain age to help assess trust — a newly created domain with no mail infrastructure is a strong fraud signal.

## Key Benefits

- Catch invalid, dummy, and mistyped email addresses
- Verify domain can actually receive messages
- Domain age check to flag suspicious new domains
- API-driven, automation-ready
- Suitable for high-volume verification

## Features

### Invalid Email Detection
Catch dummy, mistyped, and non-existent email addresses by verifying the domain has real mail infrastructure.

### Domain Trust Scoring
Returns domain age in days — newly created domains are a strong indicator of fraudulent or disposable email addresses.

### Mail Server Validation
Checks MX (mail exchange) records to confirm the domain can actually receive emails — not just that the format is valid.

### Real-Time Processing
Instant email validation for inline onboarding and registration flows.

- Staffing and HR platforms
- Financial institutions

## Use Cases

## FAQs

### What input is required?
Only the email address is required for verification.

### How does it catch dummy emails?
The API checks if the email domain has valid mail exchange (MX) records — domains without mail servers can't receive emails, indicating a fake or dummy address.

### What is the domain age check?
The API returns domain age in days. Newly created domains (days or weeks old) are a strong fraud signal — legitimate businesses and email providers have domains that are years old.

### Can I use this for bulk email list cleaning?
Yes. You can validate email lists by making parallel API calls to clean your contact database and remove invalid entries.

### How do I get started?
Sign up on Connect App, submit the required documents, integrate the REST API using our sandbox environment, and go live.

### Can the API handle high volumes?
Yes. The API is designed to handle large-scale volumes reliably without performance degradation.

### How does API authentication work?
Every API call is secured with one-time-use tokens generated using asymmetric cryptography. After signing up, you will receive your developer-key and secret-key for both UAT and production environments, which you can use to generate tokens for authenticating your API requests.

### How are errors and failures reported?
Every response includes a status code and a human-readable message. Failed requests return specific error codes indicating the reason, so you can handle each case programmatically.

### Is there a sandbox environment for testing?
Yes. A full sandbox environment is available immediately on signup. You can test your integration end-to-end before going live — no commitment required.

### How is API usage billed?
Usage is billed per successful API call with no minimum commitment. Volume-based pricing tiers are available — contact our team for detailed rates.
