How Email Verification Works

Syntax Checking - Syntax check is the very first step of email verification process. It is merely checking the format of an email according to pre-defined standards. If an email does not meet the specified format criteria, it will be marked as invalid.

Domain/MX Records - MX record (A mail exchanger record) is a record in the DNS that specifies a mail server responsible for accepting emails on behalf of the recipient's domain. An email address with missing MX record will be marked as invalid by bulk email verifier.

Role-based email detection - Role-based account belongs to a group of people, and mailing to them may get you blacklisted with some ISPs.

Email verifier detects and marks such email accounts from the list to prevent you from mailing to such harmful email accounts.

Disposable/Temporary email detection - As the name says, temporary email accounts are just created to bypass the sign-up or login forms. Such type of emails is destroyed automatically after some time.

Catchall server detection - Catchall email server is configured to receive/accept all emails sent to a specified domain.

Spam-trap detection - There is a possibility of the existence of spam trap in an email list. Removal of spam trap is essential for a hygienic mailing list.

Greylisting verification - Just like whitelisting and blacklisting, greylisting is another method of spam fighting. The mailbox of greylisted email account rejects the email from an unknown IP with a "try again later" message. This means that the email is delayed until it is sent again.

Mailbox Confirmation - It is the final step of email verification process. The email verifier utilizes SMTP protocol to contact the mail server and validate if the mailbox can receive messages.

Why Verify Emails?

After the email verification is completed, a list with deliverable and safe-to-send status is available for downloads that will cause fewer bounces.
