How to delete or clear blocked calls on iPhone 12

On an iPhone, blocked phone numbers have to be removed one at a time. There is currently no option to select multiple blocked numbers and unblock or delete them in bulk.

On a Mac, however, you can manage your blocked contacts more efficiently and remove multiple blocked numbers at once. This makes the Mac a much more convenient option if you have a long list of blocked numbers to clean up.

So, if you need to remove several blocked numbers, it is considerably quicker to do it from your Mac rather than your iPhone. See the pic below

For blocked email addresses, however, the situation is different because blocking is usually handled by the individual email service. Simply sign in to your email account through its web browser interface—for example, Gmail, Outlook, Yahoo Mail, etc.—and open the service's Blocked addresses / Blocked senders settings. Many email services allow you to select multiple blocked addresses and remove them in bulk, which is much faster when you have a long list.

So, for a large number of blocked email IDs, it is usually best to manage them through the email provider's websiterather than through the Mail app on your iPhone or Mac.

The calls should be in trash. Open the Trash folder, select the messages and delete them.
