Disclaimer: Email verification is not 100% accurate.
A "Likely Exists: Yes" status can occur for catch-all addresses or if a server accepts all RCPT TO commands initially.
"Likely Exists: Unknown" often means a temporary server issue (like greylisting) or no conclusive SMTP response.
This tool respects a delay between checks to the same mail server to avoid being blocked.
Firewalls or strict mail server policies can prevent successful checks.
