Accurate and Secure Email Address Validation Tool

Our email validator is a free tool for checking email addresses. It checks the email's format and the domain's validity. It also checks the mail server (MX record). This ensures the email address is active and can receive messages.

This tool is great for developers, marketers, and security experts. It helps improve email delivery rates and prevent fraud. It also keeps mailing lists clean.

Key Features of the Email Validator

• ✅ Syntax and Format Check—Makes sure the email follows the right structure

• ✅ Domain Verification—Checks if the domain exists and can be found online

• ✅ MX Record Lookup – Finds the mail servers for the domain

• ✅ SMTP Validation (Non-Intrusive) – Sends a test message to see if the email can receive mail (optional)

• ✅ Typo Detection – Finds common spelling mistakes in domain names (e.g., gmail.con → gmail.com)

Blacklist Check (optional)	Flags known disposable or spamtrap domains
