AI Can Write Your Marketing Copy, But Can It Persuade People Buy?
The human side of direct response
From Secaucus to Seattle… from Boston to Austin…. every marketing team in America is using AI in some capacity to write their sales copy.
Faster briefs mean faster drafts and faster approvals. The result? There’s a crazy amount of content being produced right now.
But sadly, the vast majority of it is not “performing” or impacting the bottom line.
If It Doesn’t Sell, It’s Not Creative.
David Ogilvy said that.
And it’s doubly true in direct marketing (DM). In DM, copy has one objective: Get your reader to take action. But there's a myth permeating marketing circles today that says if AI can write grammatically correct, on-brand copy at scale, the hard problem of copywriting is solved.
Umm, no it ain’t.
Make it stand out
Whatever it is, the way you tell your story online can make all the difference.
Because the hard problem of copywriting was never grammar, logic or syntax. It was never speed.. It was never even creativity.
“In DM, copy has one objective: Get your reader to take action.”
The hard problem of copywriting is making a stranger trust you enough to buy something from you. (See the excellent book “Seducing Strangers” by Josh Weltman).
What direct response actually requires
Brand advertising also has one job: make an impression. It lives on reach and frequency, and its results are measured in recall studies and share of voice. If it feels good, it's probably doing something (probably).
Direct response is an entirely different animal. It lives or dies on a single, measurable outcome: did the reader respond? Did they click, call, complete a form, mail back a survey, etc., etc., etc.
“Direct… is an entirely different animal. It lives or dies on a single, measurable outcome: did the reader respond?”
Every word and element on the page — the headline, the body copy, the offer structure, the images, the colors, the CTA, the P.S. — exists to move one person from passive reader to active respondent.
That’s it.
What Drives That Response Isn't Style. It's Psychology.
More specifically it’s relevance… urgency… credibility… trust… value… and risk reduction.
A reader deciding whether to ask for information about a Medicare supplement plan isn't weighing your mission statement or your company’s stance on climate issues.
They're asking: Does this solve my problem? Can I trust this company? What happens if I'm wrong?
The copy that converts is the copy that answers those critical questions — in the right way, at the right moment, with the right proof.
AI can approximate the format of that copy. It can learn the structure and cadence. But approximating the structure is not the same as understanding what's at stake for the reader.
Where AI falls short — and why it matters
Good direct marketing is good communication. Good communication is personal communicatoin.
And here's what AI doesn't have — emotional intelligence. It can’t put itself in the reader’s shoes. It can’t empathize with your reader’s challenges. It can feel your reader’s pain. It can’t relate to what the reader is feeling because it happened to live through a similar situation.
“AI doesn't have — emotional intelligence”
We’re not talking about regurgitating the demographic profile outlined in the brief, but the real essence of who the reader is, what they’re going through, why they've said no before, and what specific fear keeps them up at night.
That knowledge comes from campaign history. From experience. From constantly testing. From the uncomfortable postmortem on a package that started off strong and then stopped working. From knowing that a particular segment responds to loss aversion in Q4 but needs more aspirational messaging in Q1.
AI has no feel for that. It can pick up patterns from the Internet, which means it's drawing on an average of everything ever written, but not the one key specific insight that makes your next campaign beat the pants off the last one.
The result is copy that is technically correct — and functionally inept. It follows the conventions of direct response without understanding why those conventions exist or how to properly use them. It can look and sound like DM without performing like it.
The Strategic Layer AI Can't Replicate
Effective direct response copywriting begins before the first word is written. It begins with positioning and what’s known as our USP (Unique Selling Proposition): the one thing we can say that our competitors can't?
It requires an explanation of not just what we're selling, but how the transaction is organized and how the perceived risk has bee removed.
It demands a well thought out audience matrix, for example: which cell gets Message A, what message goes to prospects versus lapsed customers versus active policyholders, and why those are fundamentally different conversations.
These aren't executional decisions you can make on the fly. They are strategic ones. And they require a mind and an intuition that understands how human beings think and make decisions in uncertain conditions — which is, almost always, how your readers are approaching your offer.
“DM requires a mind and an intuition that understands how human beings think and make decisions in uncertain conditions”
AI is a capable “execution” tool. In the hands of an experienced DM pro, it can do research, accelerate production, generate test variations, and handle the mechanical lift of adapting proven frameworks. There’s real value in that.
But the strategic decisions that makes copy work (the positioning, the offer, the behavioral economics, the psychological sequencing, etc.) has to come from somewhere else.
It comes from years of DM experience, from testing, from having created grand controls, from being burned before, and from genuine human intuition and an understanding of what your audience needs to believe before the say yes.
That part isn't automated yet. It hopefully, it never will.
And if you're measuring your marketing by real response rates rather than mere impressions, you probably don't want it to be either.
