Once you're able to analyze your customer behavior you should be able to predict when one-time customers are likely to place their second orders.
This step, placing their second order, is a key behavior for their customer development and for your store. Especially when it comes to repeat customer purchases and loyalty.
You'll want to boost this natural behavior by sending a reminder email or full campaign to those one-time customers. Done right you have the chance to have more customers reorder, sooner, and by buying the products you want them to buy.
For the timing you'll want to use your Average Customer Purchase Latency for the second order. Repeat Customer Insights customers can use the Order Sequencing Analysis for this.
Additionally, if you know which products sell best in the second orders then promoting those would be a great idea. The Nth Product Analysis can help find those products.
