If you sell products that run out, like coffee, supplements, pet food, skincare or cleaning supplies, your next sale is already sitting in your order history. The customer liked the product. They just need a nudge at the right time and an easy way to buy again.
That is what a reorder reminder app does. This guide compares the main Shopify reorder reminder apps (also called replenishment or repurchase reminder apps) and the main alternative, building the flow yourself in Klaviyo.
We make one of these apps, Easy Reorder, so we’ve tried to keep the comparison fair and stick to what each app says on its own Shopify App Store listing. Pricing changes often, so check each listing before you decide.
Key takeaways
- Reorder reminder apps nudge customers just before they run out, with a fast way to buy again.
- The biggest differences are timing control, the reorder experience and support for guest customers.
- Easy Reorder, Replenish, Reorder Reminder Pro and Buy Again each take a different approach; a DIY Klaviyo flow is the main alternative.
- Judge any app by attributed reorder revenue over 30 to 60 days, not open rates.

What to look for in a reorder reminder app
- Timing control: Can you set a reorder interval per product, use one global interval, or let customers choose their own?
- How easy reordering is: Does the reminder land the customer in a pre-filled cart or a one-click reorder page, or just on a product page?
- Guest customers: Many Shopify buyers never create an account. Check whether guests can reorder without logging in.
- Works with your email stack: If you already use Klaviyo, Omnisend or SMS tools, see whether the app’s links or events plug into them.
- Subscription awareness: If you also sell subscriptions, the app shouldn’t remind customers about products they already receive automatically.
- Attribution: You want to see the revenue that reminders actually brought back, not just opens.
- Pricing model: Most apps charge by the number of reminders a month. Estimate your volume before you compare.
💡 Pro tip: Before comparing prices, count how many orders of consumable products you get a month. That’s roughly how many reminders you’ll send, and it decides which pricing tier you actually need.

|---|---|---|---|
| Easy Reorder | Per-product interval | One-click reorder page, guests included | Magic links for Klaviyo/SMS, smart bundling, subscription-aware, revenue attribution |

1. Easy Reorder
Easy Reorder sends each customer an on-brand reminder email just before they’re likely to run out, with their product and a reorder button.
The button opens a personalized one-click reorder page where their previous order is ready to add to cart. Guests can find their past orders and reorder without an account.
Key features:
- Reorder reminder emails based on how often each product is usually repurchased, with an editable email sequence
- One-click reorder page, including for guest customers
- Magic reorder links you can drop into Klaviyo flows, newsletters and SMS campaigns
- Smart bundling, which groups items due at the same time into one email, and skips products the customer already has on subscription
- Snooze links and product substitutions
- Analytics from delivered to opened, clicked and converted, with revenue attributed to reminders
- Custom sending domain, so reminders come from your own domain
- Pricing: Free to install at the time of writing. Check the App Store listing for current plans.
- Best for: Stores selling consumables that want reminders plus a fast, login-free reorder experience, and stores that want to reuse reorder links in their existing Klaviyo or SMS campaigns.
- Keep in mind: It’s a newer app with a small number of reviews so far. Reminders are sent by email; SMS works through the magic links in your own SMS tool rather than natively.
2. Replenish ‑ Reorder Reminders
Replenish takes a customer-led approach: the customer chooses how often they want to be reminded, based on how fast they use the product.
Reminder emails carry a pre-loaded checkout link and an optional discount, and customers can snooze, reschedule or stop reminders themselves.
- Pricing: The listing shows a free plan with a monthly reminder limit and paid plans starting at $29 a month, with higher tiers for more reminders.
- Best for: Stores that would rather let customers set their own cadence than guess the interval per product.
3. Reorder Reminder Pro
Reorder Reminder Pro schedules a reminder for each customer from their purchase date, based on usage days you set per product.
It’s quantity-aware, so two bottles of a 30-day supplement means a reminder around day 60. Emails include one-click reorder links, optional discount codes and branded templates.
An “Auto Mode” lets you set one global reminder period instead of setting up each product.
- Pricing: A free plan plus paid tiers based on monthly reminder emails. See the listing for current prices.
- Best for: Merchants who want quick setup with a global interval, or quantity-aware timing.
4. Buy Again & Reorder Reminders
Buy Again & Reorder Reminders is a broader reorder toolkit. Alongside reminders, it adds:
- A reorder popup and page in Shopify’s new customer accounts
- A “previously bought” badge
- Buy-again sliders
- Reordering on the thank-you page
Its listing describes customer-defined, usage-based and AI-based reminder timing (depending on plan), plus support for B2B and POS and integrations with Klaviyo, Omnisend and Mailchimp.
- Pricing: Several paid plans with free trials. See the listing for current prices.
- Best for: Stores, especially B2B or wholesale, that want reorder buttons throughout the storefront and customer account, not only reminder emails.
5. DIY: a Klaviyo replenishment flow
If you already use Klaviyo, you can build a replenishment flow yourself:
- Trigger on a product purchase
- Wait the expected usage period
- Check whether the customer has already reordered
- Then send
Klaviyo also offers predictive analytics such as expected next order date on some plans.
- Pros: Full control, and it lives in a tool you already pay for.
- Cons: You need a separate flow or branch logic for each product interval, and the email usually links to a product page or a cart link you build yourself rather than a reorder page.
💡 Pro tip: Many merchants combine the two approaches: a reorder app for timing and the reorder page, with its links used inside Klaviyo. Just avoid sending the same customer two reminders for the same product.
How to choose
- Most of your buyers check out as guests: prioritize a login-free reorder experience.
- You don’t know your product intervals: start with a customer-chosen cadence or a sensible global interval, then refine per product as data comes in.
- You live in Klaviyo: pick an app whose reorder links or events work inside your flows, so you don’t run two competing reminder programs.
- You also sell subscriptions: make sure subscribers are excluded from reminders for products they already get.
- Judge by revenue: whichever app you try, measure attributed reorder revenue over 30 to 60 days, not open rates.
FAQ
What is a reorder reminder app?
It’s a Shopify app that emails (or otherwise notifies) customers when they’re likely to run out of a product they bought, with a link to buy it again quickly.
Which platforms make it easy to reorder recurring items?
On Shopify, reorder reminder apps such as Easy Reorder, Replenish, Reorder Reminder Pro and Buy Again add reminders and one-click reordering. Subscription apps are the other option when customers want automatic deliveries.
Are reorder reminders the same as subscriptions?
No. A reminder asks the customer to buy again and leaves them in control. A subscription charges them automatically on a schedule. See our guide on reorder reminders vs subscriptions.
Can I use a reorder reminder app with Klaviyo?
Often yes. Easy Reorder, for example, gives you magic reorder links to use in Klaviyo flows. Just avoid sending the same customer two reminders for the same product from two tools.
What is one-click reorder?
It means the customer goes from the reminder straight to a cart or page with their previous items ready, instead of searching the store again.
