What is email verification?
Email verification is the process of checking if an email address exists, is valid, and can receive mail. It helps you identify typos, invalid domains, and non-existent accounts before you hit send.
Does this tool send an email to the recipient?
No. Our validation process is “stealthy.” We perform syntax checks, verify DNS records (MX), and ping the SMTP server to confirm the mailbox exists without ever sending an actual message to the contact.
Why is checking email validity important?
Sending emails to invalid addresses leads to “Hard Bounces.” If your bounce rate exceeds 3-5%, ISPs (like Google) will flag your domain as spammy, ruining your sender reputation and causing your future emails to go to the spam folder.
What are “Risky” or “Disposable” emails?
Our tool detects temporary addresses (like 10-minute mail) often used by bots or fraudsters. It also flags “Catch-all” servers and potential “Spam Traps,” which are dangerous addresses used by ISPs to catch spammers.
