How to scale Google Ads spend profitably for a coffee or subscription box brand

A coffee subscription business grows by keeping subscribers, not just by winning them. The figure above comes from Recharge's subscription data: 9.3% of first-time coffee and tea subscribers reached a sixth reorder, roughly six months at a monthly cadence. Nearly all of them, 99.3%, placed a first reorder, the highest rate of the five categories Recharge compared. The losses come after that, and 20.7% of coffee and tea renewal cycles ended in cancellation.

That shape decides how to scale. Early retention numbers can look strong across the board. The question is which campaigns bring subscribers who are still there at month six.

1. Measure cohort payback first. Before raising any budget, work out what your own new subscribers earn in margin over three and six months, after the subscription discount and postage. That is the most a new subscriber can cost.

   Illustrative arithmetic with made-up round numbers, not a benchmark.

   Your subscribers earn $9 of margin per full-price renewal, and your own cohorts average four renewals in six months: $36. If the first box earns $2, the most you can pay to acquire a subscriber and break even over six months is $38.

2. Cap the first-box discount. A deep first-box discount can win subscribers who leave early. Test offers against each other and compare their cohorts at month three, not their conversion rates at checkout.

3. Scale the campaigns whose cohorts stay. Tag each new subscriber with the campaign that won them, and compare how many are still active at month three and month six. Move budget toward the campaigns with the stickiest subscribers, even if their first-order ROAS is lower.

4. Keep renewals out of Google Ads conversions. Send only first orders to Google Ads, so the bidding learns from new subscribers rather than from renewals it didn't win.

5. Treat gift subscriptions separately. A prepaid gift runs for a fixed term and then ends, whatever the recipient thinks of the coffee. Give gift subscriptions their own campaigns, targets and payback maths.

6. Keep subscribers who want a break. Offer skip and pause at the moment of cancellation. Recharge's data shows coffee subscribers skip 4.0% of renewal cycles; a skip keeps the subscriber, where a cancellation ends the payback.

7. Let subscribers match delivery to how fast they drink. Offer a choice of frequency and make it easy to change. A subscriber whose bags arrive faster than they finish them builds a stockpile, and a stockpile turns into a skip, then a cancellation.

8. Decide in advance how you'll handle green coffee price rises. When green prices climb, either pass part of the rise on to subscribers or accept a lower margin per box, but choose deliberately and re-run step 1. An acquisition target set when margins were higher will overpay once they fall.

9. Separate curated boxes from coffee. Curated boxes carry different contents, costs and retention. Recharge's figures cover coffee and tea, not curated boxes, so build their payback from your own data.

What this looks like month to month

Review new-subscriber acquisition cost weekly and cohort retention monthly. Add budget only where a campaign's cohorts are on track to pay back within your window, and re-check the maths whenever green coffee prices or postage rates change.
