Free Bulk Email Verification: All You Need To Know In 2022 (2023)

What is Email Verification

Email verification is a way to check 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

Bulk email verification can make or break your email marketing campaigns so that your business can achieve its revenue goals. When you use a bulk email verifier to clean up your list, you essentially remove all invalid addresses so that your marketing emails make it to the eyes of potential customers. This increases your odds of a successful email campaign while also helping you target your ideal audience.

Free bulk email verification tools also help you maintain a healthy sender score by removing spam traps from your list. Since spam traps (or honeypots) essentially monitor email distributions to look for spam, emailing these addresses can quickly land all of your marketing emails into the spam folders of everyone on your distribution list, which hurts your overall marketing efforts. By simply removing honeypots from your list, you can easily maintain a healthier sender reputation.

Of course, a bulk email verifier can also help your budget. Since most email marketing platforms charge based on the number of addresses you send each email to, you want to make sure you’re not paying for addresses that won’t net you any returns on your investment. Cleaning up your list will save you money in the long run, which makes it a wise investment.

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 validation, fake emails are weeded out of your mailing list.

The validation process involves a 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 other words, free bulk email verifier software takes the mailing list you provided (either as a .CSV document or as a list of mail addresses separated by commas) and removes all of the following:

  • Duplicate emails
  • Invalid domains
  • Improperly formatted addresses
  • Role-based accounts
  • Disposable addresses
  • Honeypots or other bots

Once the bulk email verifier has completed its job, you can then re-export your list so it’s ready for your next marketing campaign.In the end, your mailing list will only have addresses that are worth marketing to, which will hopefully net you increased conversion rates and higher profit margins.

Of course, you want the best email verification service you can get without increasing your expenses beyond the increased profits you’ll net from an efficient email marketing list.
