Atomic Verifier Online

online email verifier

Atomic Verifier Online is a powerful email validation service that verifies email address validity.

Verify e-mail addresses in your mailing list. It’s simple:

  1. Login to your Atomic Verifier Online account
  2. Create a task and upload your email list (.csv or. txt), or manually enter email addresses for validation
  3. Click “Start Verifying” to begin e-mail validation

*Upon account creation, you get 10 free days of the service as a trial (using a trial account, you can't verify more than 100 email addresses). If you like the service, you can extend and pay for it right from your Email Verifier Online Control Panel, or buy it right now to verify up to a million email addresses.

You can also verify each email address in the list separately if you wish.

All addresses are checked in multi-thread mode, which speeds up the entire process. The average speed of email verification is from 10 to 20 emails per second, or up to 1200 emails/minute.

Correct and incorrect emails can be saved in .TXT, .CSV, .XLS, or .PDF formats.

Our online email verifier is the perfect addition to our other Atomic e-marketing tools. Collect email addresses using our email extractors (e.g., Atomic Email Hunter), transfer the emails to Verifier Online to remove obsolete addresses, and then use our bulk emailer — Atomic Mail Sender — to send your messages out! Take advatage of Atomic Subscription Manager to automatically manage your mailing list and track all subscriptions and unsubscriptions.

Our clients about Atomic Verifier Online:

I wanted to commend you all on such a great update to your Mail Verifier, and the quick 8.1 update (Gmail was naughty?) I use it almost every day, and with 8.x version it has become super awesome!!! It was great before, but its tight now! Sincerely,


My website was build to help people that had be effected by the BP oil spill in 2010. The work has included customer contact with the use of Atomic Mail Sender and Atomic Mail Verifier. Its a very solid piece of software and we have use list of 10,000 people to send emails to. The software can be set to only send 300 emails per hour per domain, this has help us not get in trouble with our hosting company when sending so many emails at one time. It can also rotate between domains when sending out giving the software great speed. We have been very satisfied with the software and we use it weekly for customer contact.
