+58% AOV with Post-Purchase Upsell: JENNY BIRD’s Success Story

About JENNY BIRD

JENNY BIRD is a female-founded jewelry brand that has captured the hearts of customers across North America, from everyday shoppers to celebrities like Michelle Obama and Hailey Bieber. Known for creating lightweight, statement pieces that elevate any outfit, the brand focuses on making fashion jewelry that empowers women of all ages to feel confident and stylish. As part of its broader mission to uplift women, JENNY BIRD directs 1% of every purchase to organizations that uplift women in need through its Possibilities Fund.

The Challenge:

As a fast-scaling ecommerce brand, JENNY BIRD focuses on increasing units per transaction and building customer retention, particularly for their stackable designs and on-trend jewelry collections.

While product recommendations across key pages, such as category, product, and cart, already offered clear opportunities to drive add-on purchases, the team wanted to expand their strategy in an effort to further increase AOV.

This prompted them to test post-purchase upsells, presenting exclusive product offers immediately after checkout when buying intent was still high. JENNY BIRD initially implemented a post-purchase upsell app, but it quickly showed significant limitations:

Limited personalization: The app required manual selection of recommended products based on cart contents and lacked 1:1 personalization based on shoppers’ unique affinities, missing opportunities for highly relevant offers.
Manual workflows: Ecommerce Manager Eryn Dunn had to create and manage 20 separate product funnels for top SKUs, an extremely time-consuming and unscalable process.
Technical constraints: The brand was unable to exclude certain orders from triggering post-purchase offers (such as those with only a digital gift card), resulting in unnecessary shipping complications for orders that didn’t originally require shipping.
Limited insight: The dashboard was not intuitive, making it difficult to quickly identify top-performing upsell products or refine offer logic.

The Solution:

JENNY BIRD implemented Nosto’s Post-Purchase Upsell as part of a broader strategy to consolidate their tech stack and leverage AI-powered personalization. Already satisfied users of Nosto’s recommendations, bundles, search, content personalization, and email features, extending their setup to include post-purchase upsells was a natural next step.

JENNY BIRD also set up exclusion rules to prevent digital gift cards and discounted products from triggering post-purchase offers, ensuring the experience aligned with both their operational workflows and promotional strategy.

They launched with a streamlined configuration: personalized product recommendations highlighting items shoppers had shown strong interest in during their session but hadn’t purchased. Each offer included a 15% discount with a one-minute time window, designed to prompt quick decisions without disrupting fulfillment operations.

The key differentiator was recommendation relevance. Nosto’s AI surfaced the right products in real-time, eliminating the need for manual setup while delivering a truly tailored post-purchase experience.

“We’re not only seeing better results with Nosto, but our prior pain points have also been eliminated. We can now make product offers highly personalized to each user and have full control over when they’re displayed.”

The Results:

Improved offer relevance, higher acceptance

With Nosto’s AI-powered recommendations, JENNY BIRD delivered upsell offers that truly matched shopper intent. Instead of cherry-picked add-ons, the algorithm often surfaced alternative variants, such as a different color of earrings that the shopper had shown strong interest in but ultimately didn’t purchase, likely due to hesitation during the buying journey.

This approach felt curated and helpful rather than pushy, resulting in a 13% increase in orders where the upsell offer was accepted compared to their previous provider.

Revenue impact: +58% AOV when offers are accepted

Among shoppers who accepted a post-purchase offer, JENNY BIRD achieved an average order value uplift of 58%—an additional $130 per order on average. This indicates customers aren’t just adding small items; they’re spending 1.5 times more than originally planned.

Since these purchases occur after checkout, they represent pure incremental revenue from the existing customer base with minimal operational effort.

Outperforming the previous provider

Compared to their previous upsell solution, JENNY BIRD gained clear advantages across all key revenue metrics:

+13% increase in accepted upsell orders
+9.3% increase in upsell value
+8.5% increase in net sales

By switching to Nosto’s AI-driven, personalized approach, they captured more of the post-purchase opportunity and drove higher overall revenue.
