Frequently Asked Questions
What email validation rules does this tool follow?
Our validator follows RFC 5322 standards for email syntax validation, including proper local and domain part checking, special character handling, and internationalized domain name support. It also checks for common formatting errors and provides suggestions for corrections.
Can I validate multiple email addresses at once?
Yes! The bulk validation feature allows you to paste or upload lists of email addresses for batch processing. Results include detailed validation reports with pass/fail status, error types, and suggested corrections for each address.
Does the validator check if email addresses actually exist?
The validator performs comprehensive syntax checking and domain validation. While it doesn't perform live SMTP verification (which would require server resources), it identifies syntax errors, invalid domains, and common typos that cause bounce rates.
What types of email validation errors can be detected?
The validator detects syntax errors, missing @ symbols, invalid domain formats, consecutive dots, invalid characters, length violations, and common typos. It also provides specific error messages and suggestions for fixing invalid addresses.
