ℹ️ Overview & Capabilities of Email Validator

Toolora Email Validator checks whether an email address is syntactically valid and backed by active mail servers. Sending campaigns to invalid or dead email addresses damages sender reputation, increases spam complaint scores, and causes email service providers (Gmail, Outlook, Yahoo) to route your emails to the junk folder.

Our validator verifies RFC 5322 syntax compliance, queries DNS MX records to confirm the recipient domain has active mail exchangers, and checks for common typos.

❓ Frequently Asked Questions

Does this tool send a test email to the recipient?
No. Our validator queries DNS MX records and validates mail server handshakes without sending any actual email to the recipient's inbox.
Why did an email fail validation even if the domain exists?
If a domain has an active website but no configured MX (Mail Exchanger) DNS records, it cannot receive emails and will fail validation.
