Based on the SMS audience etiquette principles, the most effective strategy to reduce your unsubscribe rate is to increase sending messages six to eight times per month.

This statement is false. Increasing SMS message frequency to six to eight times per month is likely to increase your unsubscribe rate, not decrease it. SMS is a highly personal and immediate communication channel. Over-messaging can quickly lead to audience fatigue, annoyance, and a perception of spam, prompting recipients to opt out. Best practices for SMS audience etiquette emphasize sending relevant, timely, and concise messages at a reasonable frequency, typically much lower than six to eight times per month, to maintain engagement and respect subscriber preferences.
