What is Email Verification

Email verification is a way to check for the validity of an email address. Without it, a business may have a mailing list of a hundred thousand addresses, and they could all be irrelevant. It helps you identify which emails are functional in order to maximize delivery effectiveness. This process can be done for a single address or in bulk.

Why You Need Bulk Email Verification

There are quite a number of reasons why you need bulk email verification. For starters, it will help you weed out malicious and fake emails. Would you rather continue sending emails to addresses that don't work or would you rather have control over your email deliverability? Cleaning your mailing list is indeed needed if you want to make the most out of your mail campaign.

It also allows you to avoid spam traps that can make your future emails be marked as spam. Spam traps are created to lure spam message senders. Any message sent to such addresses will automatically be marked as spam by service providers. As a business who relies on email marketing, the worst thing that can happen to you is having your emails end up in the spam folder.

How Bulk Email Verification Works

Each free bulk email verifier has its own algorithm for performing the validation process. It makes use of multi layer testing to check irregularities, intricate algorithms, and artificial intelligence in identifying fake mail addresses or spam traps. After a successful email validation, fake emails are weeded out of your mailing list.

The validation process involves mail address syntax check following IETF standards, domain/mx record check, role based account detection, disposable address detection, spam trap detection, DNSBLs and URI DNSBLs for blacklisting, and simple mail transfer protocol. In the end, your mailing list will only have addresses that are worth marketing to.
