Reorder reminder or replenishment email is a type of email that urges customers to order again a certain product. The assumption is that you know roughly how long does a product last and remind customers to reorder before they run out of it. It works very well for everyday items like personal hygiene products, food and coffee, beauty.
Replenishment emails should be used with caution as not to push the same offer too often. It can be tricky if your customers often buy more than one product as well. We recommend looking at your average time between orders and retention rate by product (in retention analysis) to choose some products to run a reorder campaign for.
