Introduction

STIENDA is Samsung's official store in Uruguay. As an electronics retailer, it faces a common challenge: its business relies on one-off campaigns (Cyber Monday, Black Friday, product launches). Between events, its customer base becomes inactive. Customers who used to shop there disappear. Revenue drops to zero.
‍

The challenge:

Sustaining an impact beyond one-time events

The problem is real: ‍

Without automation, revenue grinds to a halt.
In June, they found this out the hard way.

Problem

The experiment:

What happens when they turn the automation system off and on?
‍

Between March and May 2026, STIENDA shifted its focus away from automation.
Result: Revenue attributed to Data4Sales fell from USD 445.9K (March) to USD 32.2K (May).

‍

A drop of -93%.

It was accidental. But revealing.

‍

With Cyber Monday in focus (May/June), automation kicked into high gear once again.

The result was devastating:
‍

‍+1.126% growth in one month.

‍

Strategy

In June, we ran 54 automated actions focused on Cyber Monday.

54 actions that resulted in

‍$394,600

‍

No one-off campaigns. Consistent flows.
‍

  • Reactivating Inactive Customers
    ‍
  • A reminder to whoever left their cart behind
    ‍
  • Offer the complementary product
    to anyone who has already purchased
    ‍
  • Filter by category
    (Samsung Galaxy, home appliances, accessories)
    ‍
  • Perfect timing
    (before, during, and after the event)

‍

Monthly revenue: USD 394.6K attributed.
That is, 25% of total revenue for June.
‍

To put it another way: 1 out of every 4 orders in June came from automation.

‍

Results

+116% New customers

Compared to the previous month's average, June brought in 116% more new customers. This isn't paid traffic. It's automation that identifies prospects and converts them.

‍

‍

‍+134% Repeat Purchases:

Compared to May, repeat purchases rose 134%. Customers who had made a single purchase returned. Automation reminded them and offered them something relevant at just the right time.

‍

‍

‍+130% increase in recovered customers

Of customers labeled as "at risk of churn," STIENDA brought back 130% more in June than in May. People who were already on the verge of leaving came back.

‍

‍

‍

The secret:

Automation ≠ "set it and forget it"

This isn't about sending a generic email to the entire database.
STIENDA's 54 actions were:
‍

  • Each action was aimed at a specific segment
    (Galaxy buyers, appliance buyers, etc.)

  • -based timing(customers who purchased 7 days ago vs. 30 days ago receive different messages)

‍

‍

  • Not just on Cyber Monday, but for 6 months in a row
  • Dormant customers were constantly being reactivated
  • The customer base did not shrink between periods; it grew by 28.5% in H1

‍

‍

  • We do not "believe that automation helped"
  • D4S calculated exactly:
    20.8% of the orders in June came from these 54 stocks.
  • Attributed revenue: USD 394.6K. Net.

‍

‍

‍

The final number:

In the first half of 2026, automation accounted for 28% of STIENDA's revenue. In June alone, it accounted for 25%.

‍

‍

If we extrapolate: over the course of a full year, automation would account for nearly 1 out of every 3 dollars that STIENDA sells.

‍

All without a human having to run 54 campaigns manually every month. No Excel. No delays. No errors. Just machines that understand the customer, predict what to buy, deliver at the exact right time, and send personalized messages.
