Hi @wernstrom!

Glad you’re merging lists now to create a current “source of truth” to work with. That data cleanup can be painstaking, but it’s so nice to leverage once it’s done!

In Klaviyo, you can rely on the “is not suppressed” status to indicate who is an “active” profile. They’re changing some of the language in the software recently, so you might also see this phrased as IF “someone does accept marketing emails”

As for “Email Marketing Double Opted In”, this isn’t data you’d use to segment the list so it could be deleted or disregarded while merging lists. “Consent” and “email marketing consent” should both be tied to the “is/ is not suppressed” status unless one of those properties came from another ESP that was used previously. In which case, you might delete one or both of those fields as well. 

“Accepts Marketing” is something you’ll need to maintain since that’s consistently updated with profiles synced from Shopify. However, you’ll want to check on your list sync settings and make sure that “accepts marketing = true” profiles are synced with this master list you’re designating as the “source of truth.”

Warmly,

Gabrielle
