MyEmailVerifier verifies 99% emails accurately and wears the crown of the most accurate bulk email verifiers. Besides that, you'll get guaranteed delivery 99% times after sending your email list. 


Besides verifying Gmail, Hotmail, AOL & other business email services, there's a golden bonus for you. MEV is the only one to identify if the provided Yahoo/AOL address is active but disabled. Other email verifier services mark that as "active," which sounds pitiful. 


Fast, Multiple Validations, and Batch upload are the top features in their API integration, which help to verify email before it goes into your database (that's cool). Rather than just a cheap email verifier, MEV is a highly dependable one! While QEV offers 10k email verifications @$60, MEV offers the same @$21.6.


If you're a beginner seeking answers, then no worries! They provide a tremendous knowledge base. Besides, they provide special discounts to non-profits and educational institutes based on their best suitability.

What are the types of Email List Cleaning?

Real-time email list cleaning 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 sign-up forms, subscription box or a check out form on your website or blogs.

Most of the 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. There are a few notable email verifiers that offer free API for real-time email verification.

Bulk Email List Cleaning

Bulk email list cleaning is the process of 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 of time. Running an email list through bulk email verification checks and removes all kinds of bad emails, i.e. catchall, disposable, role-based, spam-trap and delivers back an email list with only legitimate emails.

Instead, the email data files are processed programmatically so that the marketers can focus on more important tasks for better email marketing.Only a handful of 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 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.
