Email List Cleaning : How it Works?

Email list cleaning is a process of running an email through vivid steps to validate the same. Here is a detailed email verification process.

Syntax Checking

Syntax check is the very first step of the 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 a missing MX record will be marked as invalid by bulk email verifier.

How does it work icon

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 email 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 a spam trap is an email list. Removal of spam trap is essential for an email list hygiene

Greylisting verification

Just like whitelisting and blacklisting, greylisting is another method of spam fighting. The mailbox of the 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 the email verification process. The email verifier utilizes the SMTP protocol to contact the mail server and validate if the mailbox can receive messages.
