Frequently Asked Questions

What makes an email address valid?
A valid email has a local part (before @), an @ symbol, and a domain part (after @). The local part can contain letters, numbers, dots, hyphens, and some special characters. The domain must have a valid format and ideally exist.
Does this tool check if the email actually exists?
This tool performs syntax validation and basic domain checks. For deliverability verification, you would need additional services that can perform SMTP checks.
Are international email addresses supported?
Yes, this validator supports internationalized domain names (IDN) and Unicode characters in domains when international mode is enabled.
What are disposable email addresses?
Disposable emails are temporary addresses from services like 10minutemail. When enabled, this tool can help identify such addresses based on known disposable email domains.
How accurate is the domain validation?
The tool checks domain format and basic DNS existence. However, a domain existing doesn't guarantee the specific email address is valid - that requires deeper SMTP verification.
