The Collector   
by ACT Consulting & Software Engineering   

The Collector is a cut down version of 'The Gatherer' which is part of Better Letter. The Collector allows you to collect subscribers for your mailing list in the same way as The Gatherer and saves it into a text file so that you can import it into other E-mail packages. Supports an unlimited number of mailing lists. Can add and remove subscribers automatically. Sends confirmation to the subscriber as well.
