hi all - quick question for you: When combining a few different lists into one list - whether it's manually uploading them or just adding them to a campaign - does klaviyo automatically remove duplicates?
Does Klaviyo automatically remove duplicate profiles when combining lists?

Hi
So, just to be specific, an email address can belong to zero, one or multiple Lists - but in Klaviyo, they exist as a single Profile (you can’t have multiple Profiles with the same email address unless you use a separate ID for Profiles).
When you add multiple Lists to a Campaign, they are automatically “de-duplicated” from that Campaign (they only get the email once from that Campaign).
If you however, send the same Campaign as separate Campaigns (each to a different List) - Klaviyo won’t de-duplicate it in that case since it doesn’t know how two or more Campaigns are related to each other (or not). You can use the Exclude Lists (to make sure they are not duplicated) from each other or turn on Smart Sending on subsequent Lists to keep things mutually exclusive.
Hope this helps!
