Email validator by DNSChecker is a free online utility that helps you check whether an email address is valid and capable of receiving emails. Our email verification tool performs multiple tests to validate an email address and give you a detailed report on email status - risk profile, delivery confidence, etc.
Email verification is the process of checking an email address before sending emails. This verification helps in spotting inactive, fake, or risky email addresses that can increase your email bounce rate.
To verify email addresses, our tool performs various checks. Based on these checks, it assesses the deliverability risk of an email address. Checks performed by our email verifier primarily include:
Our email address validator also detects disposable, catch-all, and role-based email addresses. This helps you easily identify risky or undeliverable emails.
To verify an email address:
You will get a summary stauts right on your screen, clearly telling whether the email is deliverable and safe to send or risky. You can download the complete email verification report as a PDF.
When you use our email address checker to validate an email address, you get detailed results for every check performed.
The tool clearly shows you the email verification status right at the top. Here, the tool tells you whether the email inbox is reachable and safe to send to.
Our email address validator calculates a risk score on a scale of 0 to 100. It labels the email address as Negligible, Low, Moderate, High, or Severe risk.
Our email checker also estimates a delivery confidence score on a 100-point scale. A higher score indicates that the email address will likely receive messages.
To authenticate a domain email setup, our email verifier checks six email authentication records: SPF, DKIM, DMARC, MTA-STS, TLS-RPT, and BIMI. You get to know whether each record is present or missing.
Advanced users can review the SMTP transcript to see the communication between the tool and the mail server. This information can help troubleshoot email verification and delivery issues.
In addition to basic checks, our email address validator provides a detailed report based on 9 validation tests. You get a preview of how many validation tests an email address passed and how many require attention.
Validates the email address syntax. Identifies missing characters, invalid symbols, and formatting errors that can prevent email deliverability.
Checks domain emails against role accounts. Email checker tells you whether the address belongs to a role-based account, such as admin@, info@, support@, or sales@.
Tells if email addresses come from temporary email services that users create for short-term use. Disposable email addresses are not suitable for long-term communication.
Identifies email addresses from popular public email providers such as Gmail, Outlook, Yahoo, and similar services. Helps you distinguish between business and personal email addresses.
Parked domains or inactive mail servers may not accept incoming emails. Our email verification tool checks mail exchange (MX) records and tells whether the provided address is active and valid.
Checks whether the domain's mail server is reachable through the Simple Mail Transfer Protocol (SMTP). A successful connection indicates that the mail server is active and capable of receiving emails.
Verifies whether the email mailbox exists and appears able to receive messages. This check helps identify inactive or unavailable email addresses before you send emails.
Checks whether the domain uses a catch-all mail server that accepts emails sent to any address under the domain. This helps you identify domains where mailbox verification may be less reliable.
Our email address validator is a free utility that works without any login or registration. It offers features that help you determine whether you sent an email to a valid address.

Email validation is the process of checking whether an email address is valid, active, and safe to send emails to. It also involves checking that the email address is correctly formatted, belongs to a valid domain, and appears capable of receiving emails.
Email verification helps reduce bounced emails by letting you keep your mailing list clean of inactive and risky email addresses. It also helps improve email deliverability and protect your sender reputation.
A disposable email address is a temporary email account created for short-term use. These email addresses are often used when you need to avoid sharing a permanent email address.
Sending emails to invalid or inactive addresses increases bounce rates. An increase in bounce rate can affect your sender reputation. Email validation helps you remove invalid and inactive addresses before sending emails. This way, bounce rate will be reduced, and your sender reputation will remain protected.
