Most e-commerce email programs are built entirely around acquisition: get the first order. What happens after checkout is often a single transactional receipt and nothing else. That is a gap, because the customer who just bought is, after the welcome flow, the second-highest-intent audience you will ever email, and most brands say nothing to them beyond a shipping notification.
The sequence and what each email does
| Timing | Job | |
|---|---|---|
| 1. Order confirmation | Immediately | Transactional, but still a branding opportunity. Set expectations for what happens next. |
| 2. Shipping / delivery | On dispatch and delivery | Reduce "where is my order" support tickets. Include usage tips if relevant. |
| 3. Check-in | 5-10 days after delivery | Confirm the product arrived as expected, surface support before a complaint becomes a return. |
| 4. Review request | 10-14 days after delivery | Ask for a review once there has been time to actually use the product. |
| 5. Replenishment or cross-sell | Timed to product usage cycle | The second purchase ask, timed to when they are likely to need more or want a complement. |
Time the review request to actual usage
A review request sent the day after delivery, before the customer has used the product, produces thin, low-value reviews or none at all. Time it to how long it realistically takes to form an opinion: a few days for a simple product, a few weeks for something with a learning curve. A well-timed request also produces better review content, which pays off in on-site conversion for future shoppers, not just in this flow.
The check-in email is underused and cheap to run
A short "how's it going" message before the review ask does two things: it catches problems before they turn into a negative public review or a return, and it signals the brand actually cares past the point of sale. Route any negative response straight to support instead of continuing the automated sequence, since a customer with an unresolved issue should not receive a cheerful review request three days later.
Replenishment timing depends entirely on the product
This is the email most brands get wrong by copying a generic timeline instead of using their own product's actual consumption rate:
- Consumables (skincare, supplements, coffee): trigger based on expected days-to-empty for that specific product, not a blanket 30-day rule across the catalog.
- Apparel and durable goods: a cross-sell to a complementary item works better than a replenishment framing, since the product itself is not consumed.
- Seasonal products: time the nudge to the next relevant season rather than a fixed day count from purchase.
Why this flow protects your ad spend, not just adds revenue
A functioning post-purchase sequence increases the odds of a second order from an already-acquired customer, which is the cheapest incremental revenue available to any store, since the acquisition cost is already sunk. It also reduces avoidable returns and negative reviews by catching problems at the check-in stage, both of which affect profitability in ways that do not show up directly in email reporting.
Setting this up on TheMarketer
We build the replenishment trigger off actual product data where it exists (pack size, typical usage rate) rather than a flat day count, and route check-in responses to support automatically so a flagged issue does not sit in an inbox until someone happens to check.
