My Two Brows includes a free sample pack with every size and style in a customer's first purchase. This incentivizes the initial sale, educates the customer on the product range, ensures they find their perfect fit for future orders, and ultimately increases customer satisfaction and repeat business.

A B2C company used topic tagging on reviews and discovered "free samples" were consistently mentioned in their most positive feedback. They had this perk but never promoted it. Adding it to their marketing communications directly increased customer lifetime value.

Don't try to force customers to adopt new behaviors, like a boot-buyer purchasing sandals. Instead, focus on encouraging them to buy a second pair, a newer model, or an upgraded version of the product they already love. This audience-focused approach builds on existing loyalty and is far more effective.

By placing a toy at the bottom of the cereal box, Kellogg's employs a classic "physical growth hack." This tactic incentivizes faster consumption to reach the prize, effectively doubling purchase frequency without altering the product. It’s a pre-digital version of modern strategies like streaks and notifications.

Packaging can be more than a container; it can be a feature that adds value and novelty. For a CPG brand, this could mean including unique messages, poems, or even personalized fortunes on wrappers, creating a small moment of delight that enhances the customer experience and brand story.

CPG brand Marsman includes a physical 90-day habit tracker with orders. Customers who complete it and submit a photo get a free month's supply. This gamified approach effectively pre-sells three months of product to earn the reward, directly driving repeat purchases and habit formation.

A study found sending customers a handwritten thank you note increased their future spending by an average of $52, leveraging the principle of reciprocity. This was significantly more effective than a generic printed note ($29 increase), demonstrating the high ROI of personalized, effortful gestures in customer retention.

Gifting isn't just for prospecting; it's a powerful tool for customer success. After a sale, create contests and reward key adoption activities with small gifts. This gamification encourages users to engage with your product, turning initial usage into lasting habits.

Instead of generic postcards, send customers useful branded items via direct mail, like magnets with school calendars or sports schedules. This utility-focused approach ensures your brand remains visible and top-of-mind in their home.
