What notification will the sender receive when I open an untracked email?

The sender of the email, whatever tracking system she uses, will not be notified that you have read the email nor that you clicked on any link. The sender will see the email she sent you has “not been read yet” forever after… Senders does not notify the sender that her email has been cleaned.
