In this article, we will explain how to import a list of blacklisted contacts.

While you can manually subscribe or blacklist contacts, please note that Sendinblue will automatically blacklist contacts in the following cases: 

• For emails:
  • They have unsubscribed from your emails by using your unsubscription form
  • They have marked your emails as spam
  • An email to the contact resulted in a hard bounce
• For SMS:
  • They have unsubscribed from your SMS by using your unsubscription form
  • They have unsubscribed from your SMS by replying to your SMS campaign
