How do I get customers to buy again instead of just once?
Repeat purchase rate rises most from a timed post-purchase email sequence, a replenishment reminder set to your product's actual usage cycle, and a simple loyalty programme once you have 100+ repeat-eligible customers. Businesses running these three typically see repeat purchase rate improve by 10-20 percentage points within two to three months, since most one-time buyers simply forget rather than actively decide not to return.

| Tactic | When to trigger | Effort |
|---|---|---|
| Post-purchase thank-you + tips email | 1-3 days after delivery | Low, one-time setup |
| Replenishment reminder | 80% through typical usage cycle | Medium, needs usage data |
| Loyalty points programme | After first purchase | Medium-high (app/platform) |
| Win-back email for lapsed customers | 60-90 days since last order | Low, one-time setup |
| Subscription/auto-reship option | Offered at checkout | Medium, ongoing management |
| Personalised recommendation based on last order | 30-45 days after purchase | Medium |
Do this
The steps, in order.
- Step 1
Map your product's actual usage cycle
A skincare product used daily lasts roughly 30-60 days; a supplement roughly 30 days. Set replenishment reminders to fire at 80% through that cycle, before the customer runs out and buys a substitute elsewhere.
- Step 2
Build a simple post-purchase email sequence
Three emails: delivery confirmation with usage tips, a check-in at two weeks, and a replenishment or complementary-product nudge at the point calculated above.
- Step 3
Add a loyalty programme once volume justifies it
A points-per-dollar system becomes worthwhile once you have enough repeat-eligible customers (100+ is a reasonable threshold) that the platform cost is covered by the retention lift.
- Step 4
Send a specific win-back to lapsed customers
At 60-90 days since last order, send a 'we noticed it's been a while' email with a modest incentive, rather than continuing to send the same broadcast content that already failed to bring them back.
- Step 5
Track repeat purchase rate as a core metric
Percentage of customers who buy a second time within 90 days. This single number reveals more about business health than most acquisition metrics because it's much cheaper to move.
- Step 6
Ask why lapsed customers left, occasionally
A short survey to a sample of non-returning customers surfaces fixable issues (shipping speed, product fit, price) that a dashboard alone won't show you.
Worth knowing
The bits people get wrong.
Most one-time buyers don't consciously decide never to return — they simply move on and forget, especially for lower-consideration purchases. Timed reminders exploit this correctly: they arrive at the exact moment need naturally resurfaces.
Replenishment timing only works if it's based on actual usage data, not a guess. A reminder sent too early feels like spam; sent too late, the customer has already repurchased elsewhere out of necessity.
Loyalty programmes are often adopted too early. Below a meaningful base of repeat-eligible customers, the platform fee and management time outweigh the retention lift — a simple email sequence delivers most of the benefit for free first.
Repeat purchase rate is one of the most under-tracked numbers in small ecommerce and local business, despite being cheaper to move than acquisition and a stronger predictor of long-term margin than any single campaign's ROAS.
Questions
Follow-up questions.
What's a good repeat purchase rate for ecommerce?
20-30% within 90 days is solid for most consumer categories; consumable or replenishable products can reasonably target 40%+ with good replenishment timing.
When should I introduce a loyalty programme?
Once you have a meaningful base of repeat-eligible customers, generally 100 or more, so the setup and platform cost is justified by the retention gain it produces.
How do I know when to send a replenishment reminder?
Estimate the product's typical usage duration from your own data or reasonable assumptions, then set the reminder to arrive at roughly 80% of that period, before the customer actually runs out.
Is a subscription option worth offering?
For genuinely consumable products with a predictable reorder cycle, yes — it locks in repeat revenue directly. For considered or occasional purchases, a subscription usually adds friction without matching benefit.
