Plain-language definitions of every term you'll encounter when building a reorder reminder strategy for a Shopify consumables store. Each term links directly from its anchor URL — shareable and citable.
An automated email sent to a customer when they are likely to be running low on a consumable product they previously purchased. A reorder reminder is timed based on the product's typical usage period, not a fixed interval after purchase.
A supplement brand sets a 30-day usage period for a protein powder tub. Reorder Reminder Pro sends a reorder reminder 27 days after each customer's purchase — three days before they are expected to run out.
Physical products that are used up over time and need to be repurchased. In Shopify, consumables are the highest-value category for repeat purchase automation because they have a predictable depletion timeline.
Supplements, skincare serums, pet food, cleaning refills, candles, and coffee beans are all consumables. Custom one-off products (art prints, furniture) are not.
The time between a customer's initial purchase and their expected next purchase of the same consumable product. The purchase cycle is calculated from: quantity purchased ÷ daily usage rate. Knowing the purchase cycle lets merchants time reorder reminders precisely.
A 60-count bottle of probiotics taken once daily has a 60-day purchase cycle. A customer who buys on 1 January should receive a reorder reminder around day 57–58.
The number of days a single unit of a consumable product typically lasts for one customer. Merchants configure usage days manually in Reorder Reminder Pro per product or variant. This is the core input that drives per-customer reminder scheduling.
A 250ml face wash used twice daily typically lasts 45 days. The merchant sets usage days = 45 for that product.
A system that automatically identifies past buyers of consumable products and sends them a timely prompt to repurchase — without the merchant needing to manually segment or schedule campaigns. Repeat purchase automation is distinct from subscription billing: customers are not locked into recurring charges.
Reorder Reminder Pro schedules a reminder email per customer based on their individual order date and the product's usage days. No subscription is required on the customer side.
Sending the same email to a large segment of customers at the same time, regardless of when each individual customer made their purchase. Batch blasting for reorder reminders is inaccurate: a customer who bought 3 days ago does not need a reminder at the same time as one who bought 27 days ago.
A weekly newsletter sent to all customers is a batch blast. A reminder sent exactly 27 days after each customer's individual order is per-customer automation.
A configuration mode in Reorder Reminder Pro where a single global reminder period (in days) applies to all products in the store. Merchants set one number — the app handles everything. Ideal for stores with a consistent product usage profile.
A skincare brand whose entire range is used in approximately 30 days sets Auto Mode to 28 days. Every customer gets a reminder 28 days after their order.
A configuration mode in Reorder Reminder Pro where merchants set individual usage days per product or variant. This enables precision timing when products have different depletion rates — a 30-day supplement and a 90-day supplement are reminded at the correct time for each.
A pet supply brand sells flea treatment (30 days) and a 5kg bag of dog food (14 days). Manual Mode sends reminders at different intervals for each product.
Scheduling a reorder reminder relative to each customer's individual purchase date, rather than a fixed calendar date or batch schedule. Per-customer timing ensures every reminder arrives when it is relevant to that specific customer.
Customer A buys on 3 March; customer B buys on 15 March. Both receive their reminder 27 days after their own order (30 March and 11 April respectively), not on the same date.
A Shopify app that automates the process of prompting customers to repurchase consumable products at the right time. A Shopify reorder app typically integrates with the store's order data to identify which customers are due for a reminder, then sends an email on the merchant's behalf.
Reorder Reminder Pro is a Shopify reorder app that uses per-product usage days and per-customer purchase dates to time reminder emails precisely.
Amazon Web Services' transactional email sending infrastructure. Reorder Reminder Pro currently uses AWS SES to deliver reminder emails on behalf of merchants, providing high deliverability and scalability.
When a customer's reminder is scheduled and the send date arrives, Reorder Reminder Pro triggers an email dispatch via AWS SES.
A direct URL that adds one or more specific Shopify products to a customer's cart and takes them immediately to checkout. Cart permalinks are used in reorder reminder emails to reduce friction — the customer clicks and goes directly to a pre-filled checkout rather than navigating the store.
https://yourstore.myshopify.com/cart/12345:1 adds variant 12345 with quantity 1 to the cart and opens checkout directly.
The percentage of customers who make more than one purchase from a store within a given time window. For consumables merchants, a healthy repeat purchase rate is the primary indicator of customer retention.
If 400 of 1,000 customers who bought in January also bought again within 90 days, the 90-day repeat purchase rate is 40%.
An email sent to existing customers with the goal of encouraging a repeat purchase, preventing churn, or deepening the customer relationship. Reorder reminders are a category of retention email targeted specifically at consumable product replenishment.
A winback email sent 60 days after a customer's last purchase is a retention email. A reorder reminder sent 27 days after a protein powder purchase is a retention email focused on replenishment.
A platform used for sending marketing and transactional emails at scale. General-purpose email marketing platforms like Klaviyo handle the full lifecycle of email marketing. Dedicated tools like Reorder Reminder Pro are purpose-built for a single workflow (reorder reminders) and do not replace a general email marketing platform.
Klaviyo is a full email marketing platform — merchants use it for welcome flows, abandoned cart, newsletters, and more. Reorder Reminder Pro is a single-purpose automation layer that handles only reorder reminders.
Reorder Reminder Pro implements per-customer timing, per-product usage days, and precision reorder scheduling — no batch blasting, no guesswork.
