Atomic TLD Filter Screenshot - Top Level Domain Filter - separate your mailing listAtomic Filter (ATLDF) is a software program that allows users to select automatically certain e-mail addresses from the list, based on the professional or national basis. When is it necessary and who does it need? Just a simple example - in order to get maximum return from your marketing campaign you need to split your mailing list into specific target groups and optimize your message for each one. This is when ATLDF comes in handy, separating emails into these groups - for example, .edu zone for marketing to students and academia, .de for reaching the Germans only, .com for contacting companies.

ATLDF contains all known Internet e-mail zones in its database, both geographic and professional. The latest information about Internet zoning can be found at (for geographic regions) and (professional organizations).

The way ATLDF works is very simple. First, you need to download list of e-mail addresses from a file (File/Open) and insert it from the Clipboard (File/Paste). After e-mail list is loaded, the program will automatically display which group each e-mail address belongs to. Then, all you have to do is to set the rules to indicate which types of e-mail addresses should remain. To do this, select menu View/Filter by zone or press F9 and set up appropriate filters. After you press OK, you will be able to see the remaining list (you can display all addresses by using menu item View/Show all, too). You can then save this new e-mail list to a file or copy it to Clipboard for later use. Also you may export it to our Atomic Mail Verifier to verify email.

If you wish to find the domain owners' contact information (e-mail address, fax or phone number), please use Atomic Whois Extractor from our Email Marketing Site.
