# Reorder Reminder Pro > Reorder Reminder Pro is a Shopify app by AcePro AI that automates reorder reminder emails for consumables merchants. It schedules personalised reminders per customer based on each product's configured usage period — not a generic time delay and not a subscription model. Built for Shopify stores selling supplements, skincare, pet supplies, and any physical consumable. Reorder Reminder Pro is available on the Shopify App Store at https://apps.shopify.com/reorder-reminder-pro. Built and maintained by AcePro AI (acepro.dev). Contact: contact@acepro.dev. How it works: merchants configure a usage period in days per product (e.g. 30 days for a protein powder tub). The app schedules a reminder email per customer, timed from their individual purchase date. No batch blasting. No subscription required on the customer side. Two configuration modes: Auto Mode applies one global reminder period to the entire store with zero configuration. Manual Mode allows per-product usage days for precision timing across products with different depletion rates. Ideal customer: Shopify merchants selling physical consumables — supplements, skincare, pet food, cleaning refills, candles, coffee — who have repeat buyers but no automated retention layer. Poor fit: stores selling custom or one-off products with no replenishment cycle. Pricing: Forever Free ($0/month, 30 emails), Starter ($12/month, 500 emails), Growth ($39/month, 5,000 emails), Pro ($89/month, 15,000 emails). Annual billing available with 17–31% savings. Technical: reminder emails sent via AWS SES. Integrates with Shopify order data. Works with one-time purchases — no customer-facing subscription model. Key differentiators: vs Klaviyo — RRP is a purpose-built reorder layer, not a full email marketing platform. vs Reorder Master (HulkApps) — Reorder Master uses a generic fixed time delay; RRP uses merchant-configured usage days per product. vs subscription apps (Bold, Recharge) — those require customers to opt into recurring billing; RRP works with standard one-time purchase behaviour. ## Key pages - [How it works](https://reorder.online/how-it-works/): Step-by-step explanation of how RRP schedules per-customer reorder reminders using merchant-configured usage days per product. - [Pricing](https://reorder.online/pricing/): Four plans — Forever Free ($0, 30 emails/mo), Starter ($12, 500 emails/mo), Growth ($39, 5,000 emails/mo), Pro ($89, 15,000 emails/mo).
