Email lists are Email Collector & Sender files that contain mass email. You create an email list (*.eli) when you save emails. Save as much, email lists you need.
A very useful function you can apply on the email list is that you can delete files that contain certain letters. For example if you do not need emails from Greece, you can simply delete them, typing .gr . and then click delete button.
Notice that an email can be in the list only one time. Email Collector & Sender, deletes automatically any email that appeared more than one time. In addition, it deletes incomplete or “wrong” emails like these that contain two letters they are same (firstname.lastname@example.org etc.).
To make your life easier, we also add an undo button.
