What Is Spam?
Email spam, also known as junk email, is unsolicited messages sent by email.
Sent by someone that has no prior affiliation with you. A sender that you have not opted into their mailing List and they are sending you emails that you did not wish to receive. No permission was given by you.
A Spam Complaint is a direct reply by a contact that the emails they are receiving are unwarranted. These complaints are considered very serious as the user has decided to report the emails they are receiving are unwanted or unsolicited.
