# Membership Pro
### Filter by plan subscription
For this filter, you can select one or multiple subscription plans, and refine the results based on the payment method used and the status of the plan (active, pending, expired...).
You can also select users that subscribed to a plan withing a specific timeframe. In this example, only members that subscribed to plans 1 or 2 within the last hour will be selected.\
You can for example setup a **notification message** that will be sent to the users **when they subscribe to a plan**.
you can do the same with the expiration date for their plan, for example you can setup **a reminder** that will be sent to the user **one week before the plan expires**.
