Email Validator

The email validator uses comprehensive regex pattern matching to verify that each email address follows the correct format: a local part, an @ symbol, and a valid domain with a top-level domain. It checks for common formatting errors like missing @ signs, invalid characters, double dots, and missing domain extensions.

Yes. You can paste multiple email addresses, one per line, and the tool validates all of them simultaneously. Each email gets an individual pass or fail status, and you see aggregate statistics showing the total count of valid and invalid addresses along with the validation rate percentage.

No. This tool validates email format and syntax only. It checks whether the email address is properly structured according to email standards. To verify whether an email actually exists and can receive messages, you would need an SMTP verification service, which involves sending a test signal to the mail server.

The validator detects missing @ symbols, spaces in the address, invalid special characters, missing or invalid domain names, missing top-level domains (like .com or .org), consecutive dots, addresses starting or ending with dots, and other structural issues that would prevent an email from being deliverable.
