Email Verification API — Validate Emails Before Sending

Bad email addresses cost you money. Every bounced email hurts your sender reputation, wastes resources, and can get your domain blacklisted. An email verification API catches bad addresses before they cause damage.

What Gets Checked

Our email verification API runs multiple checks:

1. Format validation — is the syntax correct? 2. MX record lookup — does the domain accept email? 3. Disposable detection — is it a throwaway address (Guerrilla Mail, Mailinator, etc.)?

Quick Start

`bash curl -X POST https://api.16761.tech/verify-email \ -H "Authorization: Bearer YOUR_API_KEY" \ -H "Content-Type: application/json" \ -d '{"email":"test@gmail.com"}' `

Response:

`json { "email": "test@gmail.com", "valid": true, "format": true, "mx": true, "disposable": false } `
