Why choose Atomic Email Verifier

Absolutely love it! Brilliant tool for marketers like me. Tried different other ones - lots of problems, bugs, incorrect harvesting, constant blockages by servers. Atomic Lead Extractor is well programmed and it gets what you really need. Definitely recommend it!

Wow its a great software. Work like magic! I love it.
Sergiy Novikov
Lead Generation Specialist
I purchased both Hunter and Verifier yesterday. I am very pleased with both products. They are much better than similar products, for example Fast Email Extractor. Your programmer has obviously been working very hard to get the bugs out of the last few versions. If you google Winston Steward, you'll see that I'm an author of end-user computer books...

Even though many people might not like this option because they might think it’s too inconvenient for them; double opt-in is still one of the best ways to check if their email address really exists or valid.

Reasons why you should use Atomic Bulk Emails Verifier

Verifying the existence of email addresses in your list is one of the most important tasks for an effective email marketing process. It will help you manage a more efficient marketing campaign and save you a lot of money by not having to use a bulk email service.

Email verifier will help you avoid sending campaigns to non-existent email addresses. So, if you have thousands of email addresses in your list, email verification tools will allow you to improve your email list deliverability the fastest way possible. Another good reason to use an email verification service is so you can be ensured that you will only get authentic leads.

This will allow you to check the validity of addresses quickly and efficiently. The validation process is performed in multithread mode by using all the benefits of the Web.

Why is email verification very important?

Most websites have their own web forms which users and customers need to fill up. While filling up these webforms, users could enter wrong email addresses intentionally or accidentally. When these forms are electronically submitted, your email list can become flooded with inaccurate and undeliverable fake email addresses. If you send email messages to fake email addresses, the bounce back email ratio will increase. Because of this, it will negatively impact your mail server’s reputation. Consequently, popular email services will blacklist your mail server’s IP address due to its poor reputation. That’s why identifying and removing invalid email addresses are essential before you start planning your marketing campaign.

By verifying email lists and checking delivery reports, you can improve many of your options such as:

  • Open Rates
  • Bounce Rates
  • Click-Through Rates
  • Conversion Rates

As you can see, email verification always results in a win-win situation.

Which emails should be verified?

Every email address and email list should always be verified. It’s always better to verify your existing lists frequently as well as your new email lists. Some people verify only new lists, or emails which were generated from untrusted sources, which is good, of course, but does not eliminate the risk completely. Although some people verify only the new lists or email addresses which were originally generated from untrusted sources, it doesn’t always eliminate the risk completely. You should always verify new email lists even those that were purchased or generated from highly trusted sources. You should always validate your existing email lists from time to time to make sure that they’re active.

Email verification is an essential process if you want to build truly effective campaigns.
