Reorder Reminder Pro vs Klaviyo
Klaviyo is a full email and SMS marketing platform. Reorder Reminder Pro is the purpose-built reorder reminder layer for Shopify consumables merchants. They are not competitors — they solve different problems. Here is when to use each, and when to use both.

How reminder timing works in each tool
The most important difference is how each tool decides when to send the reminder.
You configure 30 usage days for a supplement. Customer A buys on May 1 — their reminder sends on May 31. Customer B buys on May 15 — their reminder sends on June 14. Each customer has their own reminder date. No batch send.
You build a replenishment flow triggered by Placed Order, filter it to a product, and add a 30-day time delay. A product with a 60-day cycle needs its own flow or branch with a 60-day delay. Klaviyo also offers a predicted next-order date you can build timing around.
What you build in each tool
The steps to send a reorder reminder for three products that last 30, 60 and 90 days.
- Install from the Shopify App Store.
- Enter usage days: 30, 60 and 90 against the three products, in one list.
- Add your logo and colors to the email template.
- New orders are scheduled automatically. Orders tagged "Subscription" are skipped.
Adding a product later means entering one more number.
- Connect Shopify so order events reach Klaviyo.
- Create a flow with a Placed Order trigger and a filter for the first product.
- Add a 30-day time delay and an email with a reorder link.
- Repeat as separate flows or branches for the 60-day and 90-day products.
- Add filters to exclude subscribers and customers who have already reordered, if you need them.

Cost at different reminder volumes
Reorder Reminder Pro is priced by the reminder emails you send. Klaviyo is priced by how many active profiles you have, whatever you send them, so the two only line up on the free tiers.
| Reminder emails per month | Reorder Reminder Pro | Klaviyo |
|---|---|---|
| 30 | Free (Forever Free) | Free if you have 250 profiles or fewer (500 emails/month) |
| 500 | $12/month (Starter) | Free if you have 250 profiles or fewer (500 emails/month) |
| 5,000 | $39/month (Growth) | From $20/month (251–500 contacts), rising with your number of active profiles — see klaviyo.com/pricing |
| 15,000 | $89/month (Pro) | From $20/month (251–500 contacts), rising with your number of active profiles — see klaviyo.com/pricing |
Reorder Reminder Pro prices from its Shopify App Store listing; annual billing saves 17–31%. Klaviyo free-plan limits from klaviyo.com/pricing, checked October 21, 2026. If you already pay for Klaviyo for other email, a replenishment flow adds no extra cost there.
Reorder Reminder Pro vs Klaviyo — common questions
How long does it take to set up reorder reminders in each tool?
In Reorder Reminder Pro, setup is installing the app, entering usage days for each consumable product and branding the email template. In Klaviyo, you build a replenishment flow: a Placed Order trigger, a filter for the product, a time delay and an email with a reorder link. Products with different usage cycles need their own flow or branch, so setup grows with the number of different cycles in your catalog.
Should I use Reorder Reminder Pro or Klaviyo for reorder reminders?
If your only goal is to remind customers to reorder consumable products, Reorder Reminder Pro is built for exactly that: you enter usage days per product and each customer's reminder is scheduled from their purchase date. Klaviyo can send reorder reminders through replenishment flows, but you build each flow yourself — a trigger, a product filter, a time delay and a template — and repeat that for each product cycle.
Can I use Reorder Reminder Pro and Klaviyo together?
Yes — many merchants do. Reorder Reminder Pro handles the reorder reminder layer (timed per product, per customer). Klaviyo handles general email marketing: welcome series, promotions, abandoned cart, and newsletter sends. The two tools operate independently and do not interfere with each other.
What's the difference between a Klaviyo flow and Reorder Reminder Pro?
A Klaviyo replenishment flow starts from a trigger such as Placed Order, filtered to a product, then waits a time delay you set before sending. To cover products with different cycles you build a flow or branch for each. In Reorder Reminder Pro you enter usage days per product in one list: a 60-day supplement reminds after 60 days and a 30-day supplement after 30 days, per customer.
Does Reorder Reminder Pro replace Klaviyo?
No. Reorder Reminder Pro is a single-purpose reorder reminder tool — it does not replace a full email marketing platform. If you are currently using Klaviyo for welcome flows, newsletters, promotions, and post-purchase sequences, keep using it. Add Reorder Reminder Pro as the reorder layer on top.
Is Reorder Reminder Pro cheaper than Klaviyo for reorder reminders?
Both have a free plan: Reorder Reminder Pro includes 30 reminder emails a month, and Klaviyo's free plan includes 500 emails a month for up to 250 profiles. Reorder Reminder Pro's paid plans start at $12/month for 500 reminder emails. Klaviyo's paid Email plan starts at $20/month for 251–500 contacts and rises with your number of profiles; check klaviyo.com/pricing for your list size. The comparison is not like for like — Klaviyo does far more than reorder reminders.
