Atomic Top-Level-Domain Filter (ATLDF) is a software program that allows users to select automatically certain e-mail addresses from the list basing on the professional or national basis.
When TLD Filter is necessary
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, e.g.: "edu" zone for marketing to students and academia, "de" for reaching the Germans only, "com" for contacting companies.
