Segment vs broadcast: when blasting still wins

Segment vs broadcast: when blasting still wins
A frame: segmentation is dogma, but the honest sources admit when a flat blast outperforms.

📥 Swipe
— Segment-overhead analysis — made the cut for heresy worth hearing: under ~2k subscribers, micro-segments starve every send of statistical signal.
— RFM segmentation primer — worth your time for the model that scales: recency-frequency-monetary beats demographic guessing for affiliates.

🧪 Tests
— Re-engagement-only split test — picked it because it shows the one segment that always pays: dormant vs active, handled differently.

🚀 Deliverability
— Engagement-tiered sending note — earned its spot for the placement upside: mailing your hottest tier first warms the whole send.

Rule: small list, broadcast; large list, segment by behavior, never by attributes you guessed.
