Every brand in our case studies is a fictional example brand, including Nuvori. The numbers are modeled from realistic Shopify and Klaviyo data to show the kind of improvement we help brands make. The method is the one we use with clients.

The situation

Nuvori sells a daily probiotic. Ads were bringing in about 600 new customers a month, and almost all of them bought once and never came back. The brand had a welcome email and a cart reminder. After the first order, there was nothing.

This might be you if

  • Most of your budget goes into ads to find new customers
  • Your emails after purchase are a thank-you and a discount code
  • You don't know how many first-time buyers ever order again

What we found

Customers weren't using the product

A daily probiotic only works if people take it every day. Nobody showed customers how to start or what to expect, so many bottles sat half-used and never needed refilling.

No reminders when people were running low

There was no reorder reminder at all, so the moment a customer was ready to buy again passed without a word from the brand.

Everyone got the same emails

A customer who bought yesterday and one who hadn't ordered in four months saw exactly the same messages.

Ready-to-buy customers were ignored

People who looked at their refill or started checkout and stopped got no follow-up.

What we built

  • A welcome-to-your-routine series that helps new customers start the product and stick with it
  • Reorder reminders timed to how much each customer bought, not a fixed day 30
  • Quick follow-ups for people who browsed or started checking out their refill
  • A check-in for customers who went quiet that asks why, before reaching for a discount
  • One simple report on repeat purchases and profit per customer

The result

Revenue grew 60% while the number of new customers barely changed. The growth came from customers coming back, so every customer the ads brought in became worth more than twice as much.

The takeaway for your brand

If customers don't use the product, no reminder will bring them back. Fix the first 30 days and the reorders follow.
