Reorder reminders for research buyers: timing, wording and when to stop

Repeat buyers are where a research store's profit comes from, and a well-timed reminder is the cheapest way to bring them back. The timing and wording need care in this category: a reminder should feel like good service, not a use schedule.

Updated September 28, 2026

Time it from the order, not from the calendar

Base the reminder on when that buyer usually reorders, not on a fixed monthly blast. Look at your own data: for each product, how many days pass between a buyer's first and second order? Send the reminder a little before that point.

What the message should say

  • What they ordered last time and when.
  • The batch now shipping and a link to its lab report.
  • Whether it is in stock, and a one-click way to order again.
  • A plain way to stop these reminders.

Never frame a reminder around running out from use, or around a schedule. Stick to stock, batches and ordering again.

When to stop

Send at most two reminders per cycle, and stop for buyers who have not opened the last few. Always stop immediately for anyone who unsubscribes.

How Purity handles it

Purity's reorder reminder is a ready-made automation. It times each reminder from the gaps between that buyer's past paid orders, so it starts once a buyer has ordered at least twice. It checks the wording before it sends, sends each reminder at most once, and honors unsubscribes automatically.

Common questions

How soon after an order should a reorder reminder go out?
Base it on how long your buyers usually take to reorder that product, which you can see from your own order history.
