If you want to cancel the cable email, you can try the following steps:
press the \"Mail\" key on the remote control of the set-top box;
The TV interface will pop up the email window, according to the color button at the bottom of the window to help prompt;
Select \"yellow key\" to delete a single email;
Select the \"red key\" to delete all messages;
\"Are you sure you want to delete all email messages?\" is displayed. If yes, the email information is deleted successfully.
If you're using a set-top box, you'll find a mail button on the remote controller of your set-top box that displays a list of emails on your TV when you press it, moves it up and down to confirm that the message is open, and the exit button returns to the TV screen.
