Hi @pinupgirl,
Thanks for sharing your question with the Klaviyo Community.
If you have enabled one or more of Klaviyo's built-in integrations, contacts will flow into your account through these integrations as an active profile. These individuals may not have opted in via a signup form, but they may have purchased a product from you, opened a support ticket with your team, registered for one of your Eventbrite events, etc. They will be considered active profiles, but will not necessarily qualify as list subscriber or belong to a specific segment.
In order to capture all active profiles in your account, you can create a segment: Properties about someone > email contains @ AND is not suppressed. However, since bulk-deleting does permanently remove all data pertaining to the profile, I recommend bulk-suppressing instead. This action will retain all of the data pertaining to the profile i.e. purchase history and still “de-activate” the profile, meaning these profiles will not count towards your bill after they’ve been suppressed.
Thanks and have a great day.
