Work out when the product runs out
Use the pack size and expected daily use to estimate the supply. Then decide how early to send the reminder.
Free guide for Shopify brands using Klaviyo
If you sell products that run out, your next order starts with knowing when the customer will need more. This guide walks through the flow we built for a supplement store, from the timing to the emails themselves.
Take a look insideInside the guide
A reminder for a 30-day bottle needs different timing from one for a 90-day bottle. The guide shows you how to account for that before you write the emails.

Use the pack size and expected daily use to estimate the supply. Then decide how early to send the reminder.
Match the email to the product in the order. Add relevant, supported proof and a fallback for products that do not have an approved proof block.
See the finished emails alongside their purpose, copy, subject lines, and preview text. Use them to write a sequence that fits your own products.

Put it to work
Start with one product. Check its timing, follow the order through the flow, and use the email examples to see what needs changing.
