Top Bulk Email Verifier & Validation Software and Services


Before, I discuss the list of bulk email verifier and validation software and website, let’s discuss why you should verify the list.

  • To get better inbox delivery
  • Verification minimizes hard bounce
  • Low bounce rate means boost IP and domain reputation
  • It prevents getting blacklisted by ISP
  • To get better return on investment

Now the question arises, how often one should verify emails? Well, if you are sending newsletter weekly or at least monthly to all your subscribers then you won’t have to verify the list at all, provided automatic bounce removal is in place on your SMTP server. However, if you are not sending the newsletter to all subscribers at once or you send it once in a while, then I would say cleaning up the list every 6 months.

What is the difference between Software and Services?

The major difference between email verification software and services is in terms of functioning. While services usage their huge database build over years to quickly run customers’ email lists, software checks all email ids one by one. Several requests to ISP, without actually sending emails, irks ISP which could lead to IP blacklisting. ISP’s doesn’t like email verification tools or services.

Having said that it’s time to look at the list.


1. Atomic Mail Verifier

Atomic Mail Verifier is quite old email verifier. It verifies top ISP like Gmail, Yahoo mail, etc., and cost-effective. They also offer free trial on their software. It also checks for syntax errors in email ids and domain existence. Though it is loaded with many good features, it does have downside. It fails to verify the email addresses of many ISP.


There is a number of services available nowadays. And, all of them claim to be better than others. I have listed few services along with a comparison table to help you get started.

They also offer free email extractor and free disposable detector API. You can integrate this API with your service to stay away from spammers.
