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. Register your Atomic Verifier Online service account*
2. Login to your Atomic Verifier Online account
3. Create a task and upload your email list (.csv or. txt), or manually enter email addresses for validation
4. 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.

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 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...

I very like the three verification levels: syntax; domain existence, e-mail address existence. If you have a lot of addresses, only verifying the syntax and domain existence will be a great idea. Simon Wu
