WooCommerce reorder reminders that reach customers when they need to buy again

Want to remind customers to reorder without manually scheduling emails for every product? Thenia is an AI-powered email marketing tool that automates WooCommerce reorder reminders and replenishment emails. It analyzes how often each consumable is purchased again in your store, accounts for the quantity in the customer's latest order, and estimates when they'll need more. Shortly before that point, Thenia sends a personalized email featuring the product they already buy and a personal discount code.

How Thenia decides when to send a replenishment reminder

You don't have to calculate when each customer will run out of a product. Thenia uses your store's order history to determine when a reminder is likely to be most relevant.

  • Learns from your actual order history. It analyzes how frequently the same product is purchased again in your store instead of applying one fixed reminder schedule to every product.
  • Accounts for the quantity purchased. If a customer's last order contained two packs instead of one, Thenia adjusts its estimate because the larger quantity is expected to last longer.
  • Estimates product duration when data is limited. For newly added products without enough order history, AI estimates how long the product is likely to last and uses that estimate to help schedule the reminder.
  • Reaches customers before they run out. The reminder is timed to help customers place their next order before they need to look elsewhere for a replacement or refill.
  • Combines related reminders into one email. If several products are expected to run out around the same time, Thenia includes them together instead of sending multiple separate messages.

What's included in a WooCommerce reorder reminder email

Each reminder focuses on a product the customer has already purchased, with supporting content selected for their needs.

  • The product they already know. Their previously purchased product appears first, along with its price, making it easy to order again. Thenia never recommends products that are out of stock.
  • A personal discount code. The code is created automatically in WooCommerce, can be used only once, belongs to that specific customer, and has an expiration date. Thenia recommends a discount based on the product category, and you can adjust it.
  • Relevant AI-powered product suggestions. Additional products are selected from your catalog to complement the main item, such as coffee filters to go with the customer's preferred coffee.
  • Your store's branding. Emails feature your store name, logo, and brand colors, and customer replies go directly to you.

Which products are suitable for reorder reminders?

Reorder reminders are primarily designed for products that get used up or need periodic replacement. For durable products, Thenia recommends relevant consumables, replacement parts, and accessories rather than suggesting another device of the same kind.

  • Everyday consumables. Coffee, filters, cleaning products, cosmetics, pet food, and other items customers regularly need to replenish.
  • Replacement parts that wear out. Components with a limited useful life can trigger a reminder when they're estimated to need replacing.

For example, if someone buys a coffee maker or vacuum cleaner, Thenia won't recommend purchasing another coffee maker or vacuum cleaner of the same kind. Instead, it looks for compatible consumables, spare parts, and accessories that make sense for the customer's purchase.

This is an illustrative email example using fictional customer and order details.

Why did Sarah receive this email now? She previously ordered two packs of filter coffee. Based on the store's purchase history, Thenia knows that customers typically reorder this coffee every few weeks. Because Sarah purchased twice the usual quantity, it estimates that her supply will last approximately twice as long. The reminder is therefore scheduled shortly before she's expected to run out, featuring the coffee she already prefers and a discount code created just for her.

Frequently asked questions about WooCommerce reorder reminders

What is a reorder reminder email?

A reorder reminder, also called a replenishment email, is an automated message that encourages a customer to purchase a product again shortly before they're expected to run out. Thenia personalizes these reminders for consumable products, featuring the customer's previously purchased item and a personal discount code.

How do I send reorder reminders in WooCommerce?

Connect your WooCommerce store to Thenia using its WordPress plugin and enable the reorder automation. After signup and connection, a short 3-step setup guide helps you select and activate the recommended automations, including reorder reminders. Thenia analyzes your orders and sends reminders automatically, without requiring a separate schedule for every product.

How does Thenia know when a customer will run out?

Thenia estimates replenishment timing using your store's order history. It measures how often the same product is purchased again and adjusts the timing based on the quantity in the customer's latest order. For a new product without sufficient purchase history, AI estimates how long it will last.

Do reorder reminders include a discount?

Yes. Reorder reminders include a personal discount code that is automatically created in your store, limited to a single use, and assigned an expiration date. Thenia recommends a discount rate suited to the product category, and you can change it.

Which products get a reorder reminder?

Reorder reminders are primarily used for consumables and replacement parts that need periodic replenishment. For non-consumable products such as coffee makers and vacuum cleaners, Thenia recommends compatible consumables, spare parts, and accessories instead of suggesting another product of the same kind.

Does Thenia work with my WooCommerce store?

Yes. Thenia is built for WooCommerce and connects through its WordPress plugin. Create your account, download and install the plugin, and connect your store to automatically import the necessary data. Customer-facing emails are currently sent in Greek.
