A suppression list is a database of email addresses or other contact information that a business has decided to exclude from its marketing campaigns. This can include individuals who have previously opted out of receiving communications, those who have marked previous messages as spam, or those who have otherwise indicated that they do not want to receive further communications. Suppression lists are important because they help businesses comply with legal requirements and maintain positive relationships with their audience.
Including individuals on a suppression list can help businesses avoid sending unwanted communications, which can damage their reputation and lead to legal consequences. By keeping track of individuals who have opted out or indicated that they do not want to receive further communications, businesses can prevent future messages from being sent to these individuals and maintain their trust and goodwill.
