Email Checker
Free email checker to verify whether an email address is valid, real and able to receive mail.
Enter an email address and press Check to see the result.
How does it work?
- We check the address. First we make sure the email is written correctly.
- We check the domain. Then we confirm the domain is real and able to receive email.
- We check the mailbox. Finally we check with the mail provider whether that inbox actually exists.
What the result means. Valid: the address looks good and can receive email. Invalid: the address does not exist or cannot receive email. Risky: it may work, but we cannot fully guarantee it. Unknown: we could not get a clear answer this time.
Why use the VerifyMail email checker?
Sending messages to invalid addresses increases bounce rates and damages your sender reputation. Our free email checker verifies an email address in real time, so you only keep contacts that can actually receive mail.
- Lower bounce rates — catch invalid and non-existent addresses before you hit send.
- Protect your sender reputation — fewer bounces mean better inbox placement.
- Catch typos instantly — we suggest the right domain when someone writes “gmial.com”.
- Flag risky contacts — disposable, role-based and catch-all addresses are identified for you.
Email checker FAQ
An email checker is a free online tool that verifies whether an email address is valid and able to receive mail. VerifyMail checks the address format, confirms the domain has valid MX records, and asks the mail server whether the mailbox exists — without sending a message.
Yes. You can check email addresses for free, with no sign-up required.
It is highly accurate for most domains. We validate the syntax, the domain and its MX records, and the mailbox in real time. Some providers hide mailbox status (catch-all), so those results are marked “Risky” rather than guessed.
Yes. The checker talks to the mail server using the SMTP protocol to confirm whether a mailbox exists, so no email is ever sent to the person being checked.
Valid: the address exists and can receive mail. Invalid: it does not exist or cannot receive mail. Risky: it may work but cannot be fully guaranteed, for example on catch-all domains. Unknown: we could not get a clear answer this time.
