Hello, I want to make it possible for new customer to upload their own blacklist, which do you recommend keeping in the left menu for use? If I keep suppression, will then it only be an option to suppress those addresses when sending a campaign? Thanks Suppression Create your own suppression lists where you can import email addresses that will never receive emails from you. You will be able to select these lists to be used in various places, *such as when sending a campaign. Blacklist Create your own email blacklist to include subscribers that will never receive emails from you and that will never be added to your email lists.
