A 20% discount on a best-selling jacket means something very different to a first-time visitor than it does to a loyal customer who has already bought three items this quarter. The visitor needs convincing. The loyal customer needs to feel rewarded. Sending both the same campaign is leaving money on the table.
Customer groups in Randio determine who receives a campaign. They are the foundation every other decision builds on — your strategy, product selection, and discount depth should all follow from who you are targeting.
Why segmentation matters more with personalized catalogs
Traditional discount codes are one-size-fits-all. If you send "SPRING20" to your entire list, segmentation is mostly about email copy. But with Randio, each customer gets a unique catalog of products and prices. That changes the equation: you can pair different strategies with different segments and see genuinely different results.
A returning customer who trusts your brand will convert on a smaller discount applied to premium products. A lapsed customer who has not bought in six months needs a different hook entirely. Segmentation lets you match the right offer to the right mindset.
Three segments to consider
The discount ranges below are starting points, not rules — calibrate them to how your store already discounts. If you rarely go below 10% off, a tighter range still feels special; if you regularly run deep sales, you may need to go further to stand out. The point is matching the offer to the relationship, not hitting an exact number.
1. VIP repeat buyers
These customers have purchased two or more times. They already like your products. For this group, use deeper discounts (25-35%) on your best or newest items. They convert at the highest rates, and the discount feels like a genuine reward rather than a desperate plea.
2. Lapsed customers
Customers who bought once, 60-180 days ago, and have not returned. They know your brand but something did not bring them back. A broader product selection (6-8 products) with moderate discounts (15-25%) works well here. You are re-introducing your catalog and giving them more chances to find something they want.
3. First-time buyers
These are customers who have an account or have engaged with your store but never completed a purchase. Keep discount amounts accessible (10-20%) and choose products at lower price points. The goal is to reduce the risk of a first purchase, not to give away margin on items they have no relationship with yet.
Smaller, well-targeted groups consistently outperform large blasts. A 200-person VIP campaign will almost always generate more revenue per catalog than a 2,000-person "everyone" campaign.
No code sharing means no downside to focus
With traditional coupon codes, there is always a fear that targeting a small group wastes the effort — someone shares the code on social media or a deal site, and everyone gets the deal. With Randio, every catalog is unique to the customer. There are no codes to leak. A focused 50-person campaign is just as secure as a 5,000-person one.
This means you can safely run a high-value VIP campaign (35% off premium products) alongside a conservative first-buyer campaign (10% off entry-level items) without worrying about overlap or code abuse.
Using segments to learn what works
The same strategy applied to different customer groups reveals what each segment actually responds to. If your VIP group converts at 18% on a "deep discount, few products" strategy but your lapsed group only hits 4%, you know lapsed customers need a different approach — perhaps more products, different collections, or a longer campaign duration.
Randio tip
Start with your smallest, highest-value segment first. VIP repeat buyers give you the fastest feedback loop because they open emails, they know your products, and they are ready to buy. Use what you learn from that group to refine campaigns for harder-to-convert segments.
Segment size and statistical confidence
Very small groups (under 20 customers) can produce misleading results. A single conversion in a 10-person group looks like a 10% rate, but it is really just noise. Aim for at least 50 customers per segment when you want to draw conclusions. For A/B testing, you will want 100 or more per variant.
If your customer base is small, start with two broad groups (repeat vs. first-time) rather than trying to create five micro-segments. You can refine as your list grows.
The bottom line
Randomized catalogs are powerful, but they are not magic. The randomization handles what each customer sees. Segmentation handles who should see it in the first place. Get both right, and you stop running "discount blasts" and start running targeted campaigns that respect your margins and your customers.
