Deliverability Crisis at a Coffee Subscription Brand
Roast & Rally is a DTC coffee subscription with 82,000 active marketing contacts and 21,000 contacts that have not opened or clicked in 18 months. Over the last quarter, average open rate fell from 24% to 11%, click rate from 1.8% to 0.5%, bounce rate rose to 4.2%, and spam complaints reached 0.19%. The team sends four promotional emails per week, uses one master list, and recently switched from a shared IP to a dedicated IP. Apple Mail Privacy Protection inflates some opens, making the decline hard to read. The company also changed its signup offer from 20% off to a free mug, which attracted discount-focused subscribers. Revenue from email is down 17% year over year, but the retention manager wants to keep sending to everyone because the list is an asset. The CEO asks for a 30-day plan that protects deliverability without abandoning revenue.
1. What are the most likely drivers of the decline, and which actions should come first?

The pattern points to list fatigue and reputation damage, not a single creative problem. Four promotional sends per week to a master list that includes 21,000 long-inactive contacts is excessive. The dedicated IP switch matters because a new IP has no sending reputation; continuing high volume to unengaged recipients is exactly how a new IP gets a poor reputation. The 4.2% bounce rate and 0.19% complaint rate are both warning signs. Apple Mail Privacy Protection can inflate opens, but it does not explain the click-rate collapse from 1.8% to 0.5%.
First actions:
- Pause promotional sends to contacts with no open or click in 180 days.
- Suppress hard bounces and anyone who complained in the last 90 days.
- Verify SPF, DKIM, and DMARC, and check Google Postmaster or similar reputation data.
- Reduce cadence for the engaged remainder to two sends per week.
- Segment by recency and engagement rather than sending one master list.
The free-mug offer may have attracted low-intent subscribers, but that is a targeting issue to fix at acquisition, not a reason to keep mailing everyone. Protect the engaged core first; revenue recovery should come from relevant offers to responsive segments, not from volume.
2. Design a 30-day remediation plan that balances revenue protection with list hygiene.

Week 1 is containment. Audit authentication, suppress hard bounces and complainers, and stop all promotional sends to the 21,000 inactive contacts. Send only transactional or service messages to those addresses. For the engaged segments, cut to two sends per week and focus on high-margin offers, replenishment reminders, and subscriber-only bundles rather than broad discounts.
Week 2 is segmentation. Build 90-day and 180-day engaged lists based on clicks and purchases, not opens alone. Create a preference center with frequency and product-interest options. Keep the best customers in a separate segment so the remediation does not reduce their service level.
Week 3 is re-permission. Send a small, value-led re-engagement series to inactive contacts in batches of 2,000 to 3,000, not the whole file at once. Ask a single question: do you still want coffee offers? Offer a clear unsubscribe and a sunset path. Do not use a deep discount as the only reason to stay.
Week 4 is evaluation. Suppress anyone who did not engage after the series, review complaint and bounce trends, and set a sustainable calendar. Revenue protection comes from better targeting and repeat purchase flows, not from mailing an unresponsive list. The retention manager should see that a smaller, responsive list produces better revenue per recipient.
3. Which metrics should the CEO use to judge success, and why should open rate not be the primary KPI?
Read the worked answer
Open rate is now an unreliable primary metric because Apple Mail Privacy Protection can pre-fetch images and register opens without a human action. A rising open rate can coexist with falling clicks and revenue. The CEO should judge the program on a small set of business and deliverability metrics:
- Click-through rate and click-to-open rate on engaged segments.
- Conversion rate and revenue per recipient, segmented by engaged, lapsed, and new subscribers.
- Spam complaint rate, aiming to stay well below 0.1% and trending down.
- Hard bounce rate, targeting under 2%.
- Unsubscribe rate and list growth, to show whether the list is healthy or just shrinking.
- Deliverability signals such as inbox placement or reputation data where available.
Also track re-permission outcomes: how many inactive contacts confirmed interest, how many unsubscribed, and how many were sunset. A successful 30-day plan may reduce list size while increasing revenue per recipient and reducing complaints. The dashboard should show both engaged-list performance and total-file risk so the CEO does not mistake volume for health.
