Deepening Customer Relationships Through Data-Driven Innovation
Ally Financial is a digital-only bank with no brick-and-mortar branches, relying entirely on digital marketing to engage customers across retail banking, credit, insurance, and investment products. Despite strong brand growth, the company's CEO had made cross-selling a top-six strategic priority: expand the number of customers who hold multiple Ally products.
That mission fell to David Hixon, Executive Director of CRM & Marketing Analytics at Ally. When Hixon first read about JPMorgan Chase's successful Persado pilot, the same press release independently crossed the desks of his boss, the bank's president, and several other executives — all forwarding it with the same note: we should check this out.
"Cross-sell is a foundational strategy for this company," says Hixon. "In fact, if you were to look at the six key initiatives of our CEO for the year, one of them is to expand the number of multiline customers that we have."
AI-Generated Language and Insights to Power Cross-Selling
In late 2020, Ally began a pilot with Persado to measure the impact of Motivation AI on cross-sell campaigns. Between September 2020 and February 2021, Ally and Persado ran three language experiments for the mortgage business across email and web — producing improvements of at least 25% and as much as 58% above Ally's control messages.
For each experiment, Ally's creative team provided a brand-consistent control message. Persado's platform then generated 16 variations using different narrative, emotion, punctuation, and format — tested in live campaigns with real customers. The winning combination was validated, rolled out, and measured against real results.
Integration with Ally's marketing technology stack went quickly, allowing Persado to start "speaking in Ally's voice" within weeks. Those results convinced Ally to enter a full-service contract in May 2021.
One experiment aimed to raise awareness for Ally's new Invest product. Here is the difference between Ally's original subject line and Persado's winning variation:
Improving New Product Adoption by 57% With AI-Generated Language
Between May 2021 and March 2022, Ally and Persado launched nine additional language experiments targeting cross-selling opportunities across mortgage, investment, deposit accounts, and automotive holders. Results were consistent and measurable:
- Persado's Motivation AI doubled click-through rates above all control messages
- Average conversion increase of 16% across diverse campaign types
- Pilot experiments produced 25%–58% improvement in customer engagement
- 12 total experiments run across email and web channels
Beyond the numbers, Hixon found a second source of value: understanding the why behind customer behavior. Post-campaign debriefs became a regular source of insight into customer motivation — informing not just future campaigns, but broader marketing strategy.
For a digital-only bank whose entire customer relationship exists on a screen, the ability to understand and motivate customers through language is not a minor capability — it is a core competitive advantage. Ally entered the Persado relationship looking for cross-sell lift. What they found was a sustainable system for understanding customer motivation at scale.
