How to read these results
Historical 2023 account record, reviewed for publication on 22 July 2026. Three-month before-and-after account comparison. The recovered source reports CAC improvement between 44% and 45%; the approved wording is approximately 45%.
The full story
Osée wanted more stability in Meta acquisition before scaling its budget. The account needed a clearer stream of customer-event data so the delivery system could learn from more of the purchase journey.
The challenge
The brand’s existing setup was not sending a complete view of customer activity to Meta. That reduced the feedback available for attribution and optimization and made aggressive budget growth harder to evaluate.
What changed
Osée connected Bily’s Edge Pixel to send customer events through a server-side path. Three months later, the recovered record reports more than 50% additional data reaching the Meta pixel and stronger Event Match Quality across the tracked events.

The result over three months
Over the same three-month period, Osée tripled its Meta spend while reducing customer acquisition cost by approximately 45%. The original headline and announcement report a 44% reduction and the body reports 45%; the approved wording preserves that difference as ‘approximately 45%.’

What the comparison shows
Osée scaled spend materially while acquisition cost improved, and the source record attributes much of that progress to stronger tracking according to the brand’s media-buying team. The evidence is observational, however, rather than a randomized experiment.
Creative, offer, audience, auction conditions, and demand can also affect performance. These figures describe Osée’s 2023 account and are not a guarantee of future results.
