@Phil Grabowski that's pretty good to test a lot of creatives. I'd probably start with an ABO campaign testing different creatives and the ones that work best after a few days, create a CBO for them.

@Phil Grabowski $5k a month is about $165 a day, so I wouldn't launch all 75 at once. Round 1: your 8-10 strongest concepts in 2-3 ABO ad sets, one hook per video. Then test the other hooks on the winners only, and move the best into a CBO to scale. What's the client's break-even cost per purchase?
