Learn how Lokaal India's free real-time validator helps you protect sender reputation and maximize inbox deliverability.
Our pipeline tests the email in 3 stages: first, it checks syntax against RFC specifications. Next, it queries global DNS servers for active MX (Mail Exchange) records. Finally, it performs a live SMTP handshake with the recipient mail server up to the RCPT TO command to check if the mailbox exists, without ever sending an email.
No, absolutely not. The tool opens a direct socket handshake with the recipient mail server and terminates the connection before the DATA command. The recipient will never receive any notification or spam.
Safe means the mailbox is confirmed active and deliverable. Risky indicates catch-all domains, role accounts (like admin@ or info@), or full inboxes. Invalid means the mailbox does not exist, the domain is dead, or the address has syntax errors.
Yes! Use our Bulk CSV Validator to verify up to 50,000 email addresses in parallel. You can download clean lists with all dead emails automatically removed.
