Subscribers allows you to view more than 30 days of data in the Subscribers performance reports.
This would allow you to go back up to 90 days and analyze your prompt performance, your new subscribers, and unsubscribe pattern.
This will allow you to gauge which days worked better for you in terms of new subscribers, and which days you got more unsubscribes. This would provide more insights into how your notifications impact the existing subscribers.
To visualize this data, open the Subscribers Performance report from the left sidebar, and toggle the date range option.
Then on the right side, you will find the date range selector to view the Subscribers performance data on a specific date range.
