Followers leave when messages are irrelevant, too frequent, unclear, or difficult to stop. Set expectations when someone follows or subscribes and keep the promise.
Use the customer’s relationship with the business to choose the message. A product update should go to people interested in that category; a service reminder should not be sent to everyone.
Review unsubscribe reasons in KobStore and change the content or frequency that creates repeated complaints. Retention is part of marketing performance.
