Quizplus · Accepted Answer

Unsolicited informative messages are those that are sent without the recipient's permission or request. In order to not be considered spam, these messages should clearly state the subject and purpose of the message in the subject line or in the opening sentence of the email. This way, the recipient knows what the message is about and can quickly decide if it is of interest to them or not.
