Is there a Plugin or other way to see how many people are subscribing?

I’ve been using phpList for well over 10 years now, but am unable to see basic things like how many people subscribed in the last 7 days, or how many in the last 30 days. Does anyone know how I can do this? Is there a plugin I need?

@keeenone You can try the Subscribers plugin which has various reports. Follow the “Find plugins” link on the Manage Plugins page.
