How Smaller Customer Segments Yield Bigger Impact During Peak Shopping Weeks
Targeting smaller customer segments during high-impact retail weeks— like Mother’s Day, Back-To-School shopping, and others—leads to stronger engagement and better results. Here’s how
Generic campaigns just don’t cut it anymore – especially during peak shopping weeks. Customers expect personalized, timely, and relevant interactions across all channels. To maximize engagement and ROI, brands must move beyond basic segmentation methods and embrace dynamic, behavior-driven customer segmentation that adapts in real-time.
Key takeaways:
While marketers can deliver personalized experiences that truly resonate with customers, many still rely on broad, batch-and-blast campaigns by default, designed to reach as many customers as possible and drive mass awareness. However, personalization truly moves the needle—delivering the right message to the right target group on the right channel at the right time.

Why Personalization Matters
Customers don’t just want promotions—they want to feel recognized. For a brand to earn customer loyalty, it must provide an excellent experience and show customers that they are being seen, understood, and valued. Batch-and-blast campaigns miss this entirely, treating everyone the same and skipping the chance to create meaningful moments.
Brands build trust, loyalty, and long-term value by sending sincere thank-you notes, making timely offers, and communicating a message that resonates. Every action should not be a transaction but rather an interaction that creates a more meaningful relationship between the brand and the customer.
In uncertain times, with rising costs and shifting habits, that emotional connection matters more than ever. By leveraging behavioral data and real-time segmentation, brands can meet customers where they are, offering value, reassurance, and relevance when it matters most. Personalization isn’t just a tactic—it’s a necessity.
From Personalization to Precision: Smaller Segments Mean Higher Response Rates
Optimove Insights recently conducted two analyses of customer segmentation: Peak shopping week campaigns (Black Friday/Cyber Monday) and in-store versus online shopping. Both reveal a compelling pattern: targeting smaller, more specific audience segments with granular segmentation consistently drives stronger engagement and higher response rates.
Finding #1 – Holiday Campaigns Had Higher Response Rates
A leading retailer sent out Holiday Batch & Blast Campaigns designed to target many customers and prepare them for Black Friday and Cyber Monday shopping sales. Within these campaigns, the ones with smaller, more targeted group sizes tend to see a much higher response rate than those with larger group sizes.
Target group sizes in these campaigns ranged from 776,452 on the low end to 14,398,812 on the high end. A total non-unique number of 138,362,644 customers were targeted.
As shown in the chart above, there was an average 1% increase in response rate when smaller group sizes were used. A one percent uplift from a group of 776,452 customers resulted in approximately 7,765 responses(!) Scale that across multiple segments, and the gains become exponential. Therefore, a high correlation exists between an increase in response rate and smaller group sizes in campaigns.
Optimove Insights also analyzed a leading stationary retailer’s in-store marketing messages compared to its online messaging. In-store marketing messages were shown to large groups of customers at their brick-and-mortar shops, while online marketing messages were sent daily to much smaller group sizes, which raked in much higher response rates than in-store.
In-store campaigns had an average group size of 5,185 and an average response rate of 0.55%. Online campaigns had an average group size of 1,106 customers and an average response rate of 2.27%, further showcasing the correlation between smaller group sizes and higher response rates.

Personalize All Communications: Tailor messages to reflect the customer’s current journey stage, ensuring relevance and timeliness.
Time It Right: Leverage predictive models to anticipate customer needs and preferences, delivering messages at optimal moments.
Avoid Batch-and-Blast: Instead of generic campaigns, focus on dynamic segments that evolve with customer behavior.
