How to delete 139 email reminders in batches on Apple phones?

If you want to delete SMS in batches, you can enter the information list, click "Edit" at the top left of the page, check the SMS you want to delete, and then click "Delete" at the bottom right corner (IOS8 system). Dear, if you think there are too many email reminders in the 139 mailbox, you may wish to log in to the mailbox, enter "Settings-Email Filtering Reminder-Email Arrival Notification" and set the display mode to "Aggregation Display", as shown in the following figure, so that the received email arrival notifications will be displayed in aggregation mode, which is more concise and convenient! I hope I can help you!
