Instantly verify if a domain accepts all emails — even invalid ones.
Want to check if a domain accepts all emails, even invalid ones? Our Catch-All Domain Checker uses real-time SMTP verification to detect whether a domain is configured to receive messages sent to any email address, regardless of validity.
