A secure list is used for email suppression. It is essentially an encrypted 'Do Not Mail’ list. It is very common for some brand marketers to utilize more than one email platform for their email campaigns. This practice is especially true when they partner with affiliates who send emails to the same shared contact lists but on separate platforms.
It is important to ensure that a contact who opts out from the email program to no longer receive emails, doesn't receive them regardless of who is sending the emails on behalf of that brand. 3rd parties such as UnsubCentral act as a centralized collecting point for email opt-outs. They will then share the opt-out lists with all the marketing agencies sending emails on behalf of that brand. The email addresses themselves are encrypted (typically as an MD5 hash) to maintain privacy.
How it Works
If a campaign includes reference to a Secure Suppression List, then Maropost Marketing Cloud will create an MD5 hash of every email address in the campaign’s targeted audience. Next, it removes any contact from the targeted audience whose email hash is contained within the specified secure suppression list.

When creating a campaign, on Step 1 of the Campaign Editor, simply place your mouse cursor in the field labeled 'Select Suppress Secure Lists' and start typing the name of the Secure List you want to use. The field will auto-fill with the name of the list as you continue typing.
