This feature allows to enable newsletter-style subscriptions via SMS. When someone sends a message to your SMSEagle device which includes a defined text, the sending number will be automatically added to a Phonebook group. This group can be later used to send messages via web-GUI/API/Email To SMS. Automatic removal from the group works the same way: when incoming SMS contains a defined text, the sending phone number will be automatically removed.
