Analytical Proof & Invariants
Machine PrecisionGoverning Mathematical Formula:
RPR = Campaign Sales Revenue / Delivered Recipients | Net ROI = [(Revenue - Cost) / Cost] × 100
Step-by-Step Mathematical Derivation
1
Delivered Recipient Value (RPR)
RPR = Revenue ($14,500) / Delivered (65,000) = $0.223 ≈ $0.22 per recipient delivered.
2
Unique Engaged Opens
Unique Opens = 65,000 × 24.5% = 15,925 unique readers.
3
Revenue Per Unique Open
RPO = Revenue ($14,500) / Opens (15,925) = $0.9105 ≈ $0.91 per opened email.
4
Campaign Net ROI
Net Profit = $14,500 - $650 cost = $13,850. Net ROI = ($13,850 / $650) × 100 = 2,130.8% return.

Frequently Asked Questions
What is a good Revenue Per Recipient (RPR) for e-commerce broadcasts?
General promotional email blasts typically achieve an RPR between $0.10 and $0.25. High-intent automated flows (abandoned cart, post-purchase replenishment) frequently achieve RPRs between $1.50 and $4.00.
How did Apple's Mail Privacy Protection (MPP) impact open rate tracking?
Apple MPP pre-fetches email images, artificially inflating open rates. Because open rates are now less reliable, top DTC operators rely on Revenue Per Recipient (RPR) and Click-to-Purchase conversion rates as their primary performance metrics.
