Not you, or no more letters
A letter reached the wrong person, or you would rather not hear from us.
-
Step 1: Reply to the letter
Say it is not you, or that you would rather not receive these. A person reads every reply and acts on it.
-
Step 2: Do not use its links
If the letter was not meant for you, do not open its buttons. They were made for the person it was written to.
