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.
In the Add or edit subscriptions rule window:
- You can add rule name
- Select group from Phonebook
- Define phrase which adds the phone number from incoming SMS to the group
- Define phrase which removes the number from the group
- Select if the phrase should be case sensitive
