Two-Year Performance Report: Legacy Autoresponder Sequence
Analyzing the long-term ROI of a 24-month automated email sequence. Tracking decay rates and the compounding value of a 'boring' asset.
Two-Year Performance Report: Legacy Autoresponder Sequence
In May 2024, I built a 52-week autoresponder sequence for the “Home Services” niche. The goal was to create a “set and forget” asset that monetized leads long after the initial acquisition. This report analyzes the performance data after two full years of operation.
Sequence Architecture
The sequence consists of 104 emails (delivered twice weekly). - 70% Educational/Contextual (value-based) - 30% Offer-driven (direct response)
The offers are rotated every 6 months to prevent fatigue, but the core educational content remains static.
Open Rate Decay Analysis
The primary metric for a long-term sequence is the decay rate of engagement. - Month 1-3: 42% Open Rate - Month 6-12: 28% Open Rate - Month 13-24: 19% Open Rate
While a 19% open rate after two years seems low, the cost of delivery is near zero. Every click generated in Month 24 is pure profit, as the acquisition cost (CPA) was fully amortized within the first 60 days.
Revenue Per Subscriber (RPS)
Total revenue generated by the sequence over 24 months: $8.40 per subscriber. Initial CPA: $4.50. Net Profit: $3.90 per subscriber.
The sequence achieved break-even at day 72. From day 73 onwards, the asset has been generating a “compounding quiet win.”
The “Forgotten” Offer Success
The most surprising data point came from an email sent in Week 40 of the sequence. It promotes a niche “Emergency Pipe Repair” guide. Despite the late placement in the sequence, it maintains a 4% CTR and a 12% conversion rate.
Lesson: User intent doesn’t expire. A subscriber who joins in January might not need a specific service until October. A long-term sequence captures this delayed intent that short-term campaigns miss.
Optimization: The “Ghost” Pruning
To maintain deliverability, I implemented an automated “Ghost” pruning rule. If a subscriber does not open any of the last 10 emails, they are moved to a “cold storage” list and eventually deleted. This keeps the active list clean and ensures the 19% open rate reflects a healthy, engaged core.
Conclusion
The legacy autoresponder is the most boring, yet most reliable, part of the portfolio. It requires 4 hours of maintenance per year and produces mid-five-figure returns. The strategy for Q3 is to replicate this architecture for the “Finance” and “Personal Development” sites.
