Are there any watermarks on the output?
No watermarks, ever. Unlike some other free tools that add branding to your output, Email Validator gives you clean, watermark-free results every time.
How does email validation work?
Email Validator checks email syntax, domain MX records, and disposable email patterns. It doesn't send any emails to the address, so the recipient will never know their address was checked.
Is this tool really free to use?
Yes, Email Validator is 100% free with no hidden fees, no premium tiers, and no usage limits. You can use it as many times as you want without ever paying.
Do I need to create an account?
No account or registration is required. Just open the tool and start using it immediately. We don't collect your email or personal information.
