Email Checker

Clean and Validate your Email list with Email Checker

An email verifier, or email checker, is a tool to validate that an email address exists and can receive emails. Verifying is important before contacting new recipients to avoid bounces and protect your mail sender's reputation.

What is Emails Checker?

Email Checker is an advanced tool for verifying an email address. Just enter the email address and hit the check button. It tells you whether the email id is real or fake. It uses complex methods and 9 step algorithm to verify and validate email addresses in bulk. You can verify one email or upload a million email addresses list to get it cleaned. It uses the following methods to determine valid email addresses.
First, it checks for the email address format with IETF/RFC standard conformance.
Then make sure that the domain name is valid. We also check whether it’s a disposable email address or it has a valid DNS record.
In the final step, it fetches the MX records from the domain records and connects to the mail server (via SMTP and simulates message delivery) to ensure that the mailbox for this user/address actually exists.
