Since Kristine has been getting many unwanted emails which she did not sign up for, she might have to mark all these emails’ senders as spam so that any new emails from these senders would immediately be sent to the Spam folder.
These emails can be harmless but annoying, but it can also create unknown adverse effects later on when the email is opened. Never open the links available in these type of emails because they will certainly create damage to your computer or information.
