Time a Reorder Reminder to Land Just as Customers Run Out
Every consumable has a run-out date you can predict from the order. A postcard timed to that moment, with a QR straight to reorder, turns a routine repurchase into an automatic one, and reaches customers your reorder emails no longer do.
Last updated: 27 July 2026
Short answer: for a product with a predictable repurchase interval, schedule a postcard to arrive a little before the customer runs out, timed off the Shopify order date or a Klaviyo replenishment segment. Each card carries a unique discount code tied to that customer plus a QR straight to reorder, so the repeat order is tracked back to the individual, and a holdout tells you the incremental lift. It reaches intent at exactly the right moment, on a channel the inbox cannot crowd out.
Key takeaways
- Replenishment mail works because the timing is knowable: you can schedule to the run-out, not guess at it.
- Best fit is consumables with a regular cycle, supplements, coffee, skincare, pet food, refills.
- Time the card just before run-out, so the reorder prompt lands while the product is top of mind.
- Attribution is per recipient: a unique discount code plus a QR to reorder, measured against a holdout.
- It runs alongside reorder email and reaches the customers email no longer reaches.
Why timing beats frequency
A reorder prompt is only useful in a narrow window: too early and the customer still has stock, too late and they have already rebought elsewhere or forgotten. Because a consumable's cycle is predictable from the order, you can put one physical reminder in the letterbox at the right moment instead of sending a stream of emails hoping one lands.
How to set it up
- Connect Shopify and Klaviyo. Connect your store to TouchDrop from touchdrop.com.au so it can read the order that starts each replenishment cycle and generate per-recipient discount codes.
- Set the run-out delay per product. Work out the real consumption interval for the product and set the card to mail a little before it, so it lands just as the customer is running low.
- Design one reorder card. One clear reorder prompt, the product they bought, a QR straight to reorder, and a small incentive if the margin supports it.
- Set a holdout. Randomly withhold a slice of eligible customers so you can measure incremental reorders, not gross.
- Turn it on and measure. Let it run as an always-on trigger and review reorder rates and code redemptions against the holdout, then tune the delay.
What results are realistic
Independent benchmarks show direct mail to an existing customer list materially outperforms cold prospect mail: the ANA/DMA Response Rate Report (2018) put house-list response at 9% against 4.9% for prospect lists, close to double.
Plan around 2.5x incremental return as an honest midpoint for well-targeted retention mail; a win-back campaign on the founders' own DTC brand returned 6.2x ROI. Replenishment has favourable economics because you mail only proven repeat buyers at the moment they are ready to reorder. Always run a holdout so your own number is real.
Timing and delivery
Cards are printed and lodged inside the destination country, via Australia Post in Australia and Royal Mail in the UK. For Australian sends, plan for 3 to 7 business days in transit, and set the trigger delay so the card lands just before the run-out date rather than after it.
Frequently asked questions
What is a replenishment reminder postcard?
An automated postcard timed to arrive around the point a customer runs out of a consumable they bought, carrying their first name, a reorder prompt, a unique discount code, and a QR code straight to reorder. It turns a predictable run-out into a repeat order.
How do you time it to when someone runs out?
Set the delay from the product's real consumption cycle, so a 30-day supplement might mail at day 24 and a 90-day supply at day 80. TouchDrop schedules the card off the order date, or off a Klaviyo predicted-next-order or replenishment segment if you build one, so it lands a little before the customer runs dry.
Which products suit a replenishment reminder?
Consumables with a predictable repurchase interval: supplements, coffee, skincare, pet food, household refills. The more regular the run-out, the better mail works, because you can time the card to intent instead of guessing.
Why post a card when I already send reorder emails?
The card runs alongside your email, not instead of it, and reaches customers who have stopped opening reorder emails or never see them. A physical reminder on the counter is hard to scroll past, and the QR takes the customer straight to reorder.
How is a replenishment postcard attributed to a reorder?
Each card carries a unique discount code tied to that customer plus a QR code, so a reorder within the attribution window, 60 days by default, counts back to the campaign. Hold out a random slice of eligible customers and compare reorder rates against the mailed group to read the incremental lift.
Does it fire automatically from Shopify?
Yes. TouchDrop connects to your Shopify store, reads the order that started the cycle, and schedules the card at the delay you set, with no manual export. You can also drive it from a Klaviyo replenishment segment or a CSV.
How long does the postcard take to arrive in Australia?
A few days rather than weeks, because cards are printed and lodged inside Australia by a local mail house. Plan for 3 to 7 business days in transit, and set the trigger delay so the card lands just before the customer runs out.
What does a replenishment postcard cost?
A per-postcard rate plus a monthly platform plan, priced in AUD with GST and scaling by volume. See the pricing guide at touchdrop.com.au/guide/pricing for current rates.
