See who is on a customer list before it reaches your ads
Before a customer list goes to Meta, Google, LinkedIn or ChatGPT Ads, Baker now shows the people in it, masked, so you can catch the wrong list in time.
Since October 22, 2026, when Baker prepares a customer list for Meta, Google Ads, LinkedIn or ChatGPT Ads, the review shows the people in it, not only how many there are. It is for anyone who uploads customer lists for retargeting, exclusions or lookalikes and wants to be sure the right people are in them.
Each person appears masked, the same way Baker masks people in analytics, for example l***@company.com. You can page through the list ten people at a time and check that it holds the customers you meant, not the newsletter list or last year's export. The masked copy is only for your review and is never sent to the ad platform. On LinkedIn, when Baker replaces a list it already filled, the review also shows who is new and who is dropped.
Next time you ask Baker for a customer audience, open the list in the review before you Publish and scroll a page or two. If anything looks off, tell Baker in the chat and it will fix the list before anything goes out. Lists prepared before this change still show only their count.
