The problem

Human-written direct-response copy is limited by intuition and hard to optimise systematically at scale.

The AI approach

Persado’s “Message Machine” uses machine learning and computational linguistics over a knowledge base of 1M+ tagged, scored words and phrases to generate and test message variations, selecting the highest-performing copy for each segment.

Evidence it works

After a 2016 pilot, Chase signed a five-year enterprise deal (2019); AI-generated copy outperformed human-written copy — up to a 450% lift in click-through rates, versus a 50–200% range for human-written ads — and was extended across card, mortgage, home-equity and wealth.

What “good” looks like

Measurable, controlled CTR/engagement uplift versus human-written control copy, with brand voice and compliance preserved.

Feasibility & cost shape

Relatively contained to deploy via a vendor platform; value scales with campaign volume and disciplined A/B measurement.

Our independent view

A genuinely measurable marketing use case — but we’d hold it to brand and compliance guardrails and judge it on tested uplift, not vendor headlines.
