Reactivation Versus List Buying for a Home Goods Retailer
Willow & Pine sells home goods online and has 480,000 email subscribers. Thirty-eight percent have not opened or clicked in 12 months. Gmail represents 54% of the list, and spam complaints are 0.11%, just above the 0.10% threshold the team uses as a warning line. The brand sends three promotional emails per week, and revenue per email is down 19% year over year. New signups average 12,000 per month, mostly from a 10% welcome discount. The lifecycle manager proposes buying 200,000 third-party contacts to offset list fatigue. The CFO wants proof that email is still profitable. The team has one email designer, one copywriter, and access to a customer data platform that can segment by last engagement and purchase history.
1. Evaluate the proposal to buy 200,000 third-party contacts. What is the likely outcome and what should the team do instead?
Read the worked answer
Reject the purchased-list proposal. It does not solve engagement fatigue; it adds contacts with no relationship, no demonstrable consent, and unknown acquisition context. With Gmail at 54% of the list and complaints already at 0.11%, a purchased list is likely to raise complaints, bounces, and spam-trap hits. That damages domain and IP reputation, which can reduce delivery for the engaged 62% of the list. It also creates legal and privacy risk depending on consent rules.
The better path is to segment the 38% inactive group, which is about 182,000 subscribers, and run a defined reactivation and sunset process. Suppress the deeply inactive from regular promotions immediately. Send a short win-back series to those with prior purchases or plausible interest. If they do not engage, move them to a low-frequency list or suppress them. Meanwhile, protect deliverability by reducing promotional frequency for active subscribers and cleaning bounce addresses.
Quantify the trade-off for the CFO: 12,000 new signups per month are a healthier growth source than 200,000 unengaged records. Show revenue per 1,000 delivered and complaint rate, not list size.
2. Design a 90-day re-engagement and sunset plan with segments, cadence, and decision rules.

Segment the inactive group by past purchase, last engagement date, and acquisition source. Do not treat all 182,000 alike. Past purchasers with no recent engagement deserve a win-back series with a relevant product incentive. Never-purchased subscribers from a discount offer should get a lower-cost content or category-interest series, not a deeper discount by default.
Days 1-30: suppress inactive addresses from the three-per-week promotional calendar. Send a three-email re-engagement series at days 1, 7, and 21. Use clear subject lines, one primary CTA, and a preference center. For past purchasers, include a time-bound reactivation offer; for never-purchasers, lead with bestsellers or a category guide.
Days 31-60: anyone who opens or clicks re-enters the active segment at a reduced cadence of two sends per week. Non-responders get one final confirmation email. Days 61-90: suppress non-responders from marketing, keep transactional mail, and document the sunset rule. Track reactivation rate, complaint rate, unsubscribe rate, and revenue per 1,000 delivered. Set a rule that any send driving complaints above 0.08% is paused and reviewed.
3. What metrics would prove deliverability and profitability improved, and how would you avoid vanity metrics?
Read the worked answer
Use complaint rate, bounce rate, unsubscribe rate, and revenue per 1,000 emails delivered as primary metrics. Open rate is increasingly unreliable because of privacy features and image blocking, so do not use it alone to judge success. Click rate and conversion rate matter, but they must be tied to delivered volume.
For deliverability, track Gmail Postmaster Tools reputation if available, spam complaint trends, and the share of sends going to engaged versus unengaged segments. A falling complaint rate below 0.05% and a lower bounce rate are meaningful. For profitability, compare revenue per 1,000 delivered and total email-attributed revenue against the prior 90 days, while accounting for seasonality and promotional calendar changes.
Avoid vanity metrics such as total list size, raw open rate, and number of emails sent. A smaller list with higher delivered revenue is a better outcome. Also measure reactivation rate and the cost of incentives. Present a simple before-and-after table with delivered volume, complaints, unsubscribes, revenue, and revenue per 1,000 delivered.
