Apple has added a new toggle to the top of the Subscriptions page on the iPhone and iPad. By clicking on the button, the user can choose not to receive e-mail notification each time a recurring In-App Purchase is charged.
It is a little more, but may be welcomed by Apple users that have a large number of subscriptions.
The default behavior is that Apple sends you a notification each time the subscription is at your expense.
For example, if you subscribe to the Apple of Arcade for $4.99 per month, you will receive an e-mail of the receipt of the first time you sign up and another every month. They serve as a reminder that you have been billed for this period.
The number of e-mails repetitive batteries rapidly that you accumulate active subscriptions, especially those that renew a monthly or weekly basis. If this becomes too annoying, you can now turn these off.
