What Is a Bulk Email Verifier (and How Do They Work)?

Bulk email verifiers are vital online tools for any person or company using and sending mass emails.

These verifiers scan email addresses, verifying that each is a valid address, within seconds. With an email verifier, you’ll know that you’re sending emails to valid addresses, avoiding bouncing problems and extra costs for hosting unused addresses.

These tools verify email addresses through a series of processes that depend on the tools themselves, so they can confirm that the email addresses are valid.

The process usually looks something like this:

  1. Syntax check: verifies that the email address is properly written and formatted.
  2. Domain and records check: verifies that the email address domain is valid, meaning the website hosting the email is a valid website.
  3. Role-based detection: checks and flags email addresses that aren’t necessarily from an individual, like “no-reply,” “admin,” “sales,” etc.
  4. Throwaway check: verifies that the email address isn’t a disposable address meant for collecting spam.
  5. Spam trap verification: ensures that the email address isn’t a blacklisted address or one designed to detect spam.
  6. Final verification: if all processes come back fine, the algorithm will usually perform one last check by pinging the address to ensure that it exists.

Although it looks like a lengthy process, bulk email verifiers go through these and more steps with hundreds or even thousands of emails in a matter of minutes.
