What Happened to Our Meta Ads in March 2026

Daily blended costs across all our campaigns · February 15 – April 15, 2026

The 30-second story

Andromeda barely scratched us. Then we chose to pay more — for better subscribers.

Meta's new "Andromeda" ad system spiked industry CPMs 15–40% in early March. Our blended cost per subscriber barely moved through both spike weeks. Around March 24, we deliberately traded volume for quality — from ~5,000 form-submit subscribers/day to ~1,000 Beehiiv-engaged Lead subscribers/day. Cost per sub went up. We chose that.

Blended cost per subscriber & blended CPM

All campaigns combined. Red zones = the Andromeda CPM spike weeks (Feb 26 – Mar 2, and Mar 15 – Mar 22, the week 1440 flagged). Green line = Mar 24, the day we shifted campaigns. Green zone = our higher-quality subscriber era.

Post-pivot

How much we spent each day across all campaigns

Daily spend dropped from ~$10–14K (volume play) to ~$2K during the pivot, then rebuilt to ~$6K/day on the higher-quality campaign.

+20%

Blended CPM rose ~20% during the Andromeda spike weeks (Feb 26 – Mar 2 and Mar 15 – Mar 22), matching the lower end of the 15–40% industry range.

~$3

Our blended cost per subscriber held flat at ~$2.40–$3.40 through both spike clusters. Non political acted as a cheap-volume buffer.

5,000 → 1,000

Subscribers per day after the Mar 24 pivot. Volume dropped, but each subscriber is now a Beehiiv-engaged Lead (welcome-email opener/clicker), not just a form-submitter.
