What are the types of Email List Cleaning?

Real-time email verification through API

Real-time email list cleaning API is used to validate email addresses on a real-time basis, i.e., emails are checked when they are entered in signup forms, subscription boxes, or checkout forms on your website or blogs.

Most email verification vendors combine their API plans with bulk verification plans, e.g., real-time API verification is also available if you sign up with their bulk verification plans. In addition, a few notable email verifiers offer free API for real-time email verification.

Bulk Email Verification

Bulk email list cleaning means cleaning an entire email database at once. The email database can have any number of emails in thousands, millions, etc. You can upload an entire list of email addresses in .csv or .xls format. A list of 1 million email addresses is usually processed in less than 24 hours. Running an email list through bulk email verification checks and removes all kinds of nasty emails, i.e., catchall, disposable, role-based, spam-trap, and delivers back an email list with only legitimate emails.

Bulk Email List Verification through API

Unlike uploading & batch cleaning, bulk cleaning API removes the manual process of uploading, cleaning, and downloading the files. Instead, the email data files are processed programmatically so that the marketers can focus on more critical tasks for better email marketing. Unfortunately, only a few email list cleaning companies offer bulk cleaning through API, i.e., MyEmailVerifier, ZeroBounce, EmailChecker, and HuBuCo.

Email List Cleaning: How it Works?

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

Syntax Checking

A 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. Verifier tools will mark an email invalid if it does not meet the specified format criteria.

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 the bulk email verifier.

How does it work icon

Role-based email detection

The role-based account belongs to a group of people, and mailing them may get you blocklisted 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 created to bypass the sign-up or login forms. Such types of emails got 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 a spam trap in an email list. Therefore, the removal of spam traps is essential for 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. It 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.
