Atomic Subscription Manager (ASM) is a program for automatic management of subscriber lists, it supports an unlimited number of subscriber lists, as well as an unlimited number of e-mail addresses in each list. E.g. your users can just send messages with SUBSCRIBE / REMOVE in the subject line in order to get into / out of your subscription list. ASM is built to allow the lists to contain practically any sort of additional information, the number of rules for managing subscriptions is not limited either.
SM manages subscription or unsubscription by email subject. It lets you monitor the InBox for particular subject line and automatically save/remove the sender’s email address to/from a specified mailing lists generating notifications according to the schedule you defined.
Actually, Atomic Subscription Manager doesn’t depend on email client you use.
Just create your project in Subscription Manager by choosing the mailing list and entering the rules for managing subscriptions/unsubscriptions to that list. That is all! The program needs to be set up only once in the beginning, then it will do all scheduled tasks automatically within the specified time intervals.
