AI Tools That Drive Revenue

You know you’re supposed to test your copy. But when it comes down to it:

• You only have time to test 2–3 variants at most

• You’re drafting based on guesswork or hunches

• You can’t run them long enough to reach statistical significance

The result is slow iteration, inconsistent performance, and campaigns that never quite reaches their full potential. That’s why Postscript built a tool called Infinity Testing.


Infinity Testing combines generative AI with predictive analytics to automatically create and test hundreds (even thousands) of on-brand message variants across your flows and campaigns.
Here’s how it works:

• You define the type of message (e.g., abandoned cart, welcome, post-purchase)

• Postscript’s AI generates high-quality, brand-aligned copy variants

• Each variant is sent to real subscribers and measured against control performance

• Over time, the model evolves—only deploying what’s proven to perform

It’s like having a 24/7 team of SMS copywriters and data analysts—but automated.

Worried about AI sounding off-brand? Valid.

With Postscript’s Brand Center you can:

• Upload your tone and style guidelines

• Feed past campaign examples into the model

• Set preferred phrasing, disclaimers, and CTAs

This means your messages will sound like you—not a generic chatbot.
Want snarky, smart, and concise? Done. Prefer earnest and heartfelt? Also done. AI is powerful, but context is everything—and Brand Center provides it.

With AI-assisted campaigns, you no longer have to:

• Write every message from scratch

• Guess the best angle or hook

• Choose between funny vs. functional copy

Instead, the AI generates multiple variations. You approve the ones that work for your brand. Then Postscript distributes and measures performance across your audience.

High-performing variants are scaled up. Low performers are retired. You learn more each time you send.

This is especially powerful for campaigns like:

• Product launches

• Seasonal promotions

• Retargeting flows

Shopper is Postscript’s AI-powered shopping assistant that brings 1:1 personalization to your SMS program at scale.

It’s trained on your brand’s voice, FAQs, and product catalog. That means it can:

• Answer product questions in real time

• Recommend items based on customer responses

• Drive conversions with natural, contextual replies

• Keep every conversation compliant and on-brand

And it does all of this instantly, without requiring a human agent to manually reply.

Some of the highest-performing variants discovered through Infinity Testing didn’t just use different wording—they used different strategies.
For example:

• Shifting from urgency to humor improved abandoned cart clickthroughs

• Using first-person (“I left this in my cart”) outperformed brand-led copy

• Adding a customer testimonial quote boosted conversions by 14

These aren’t insights you find on the first try. AI finds them for you over time.
