Step #3: Click Set up New Followers Alert.
Step #4: Choose Weekly or Monthly, enter your email address, check the consent box and click Activate Alerts.

What can I do with my new followers?
From the same list, you can follow back, remove followers, add accounts to a Twitter list or your Mass Block List, and export the list. Use Filter Options to find bot-like, inactive or egghead accounts among your new followers.
