I have an unproductive list of about 15k that I would like to move off Klaviyo for now. I would like to retain the unsubscribe/spam complainers so that, should I add the 15k list back in the future, I will not email these unsubscribes/spams.
Retention of Unsubscribe/Spam Complainers when I move a list off Klaviyo

Hi
Unfortunately, no you cannot go back and forth between suppressing and ‘re-activating’ users in a sense. Suppressions are permanent in Klaviyo. A suppressed profile can only be re-activated by a user’s own action, ie. if they re-subscribe to one of your lists using a signup form.
Moving a List of users to ‘Suppression’ will keep all their profile information and history stored. This is one of the benefits from suppressing users vs deleting them entirely from Klaviyo In order to Move your List to the Suppressions tab, I would follow our documentation here. Our documentation states that first you will need to export this list or segment to a CSV file. Remove all columns in the spreadsheet except for the column with the header Email.
Next, find your suppression list by navigating to the Profiles tab of your account. Click the Suppressed People link in the upper right of that page and select Upload File.
When you suppress a group of people, their profiles will remain intact in your account. They will be considered "inactive," however, and you will not be able to email them. Inactive profiles do not count toward your Klaviyo plan's active profile limit. Note that, this action is permanent and it is not possible to un-suppress a group of contacts.
Hope this helps!
