How Much AI Belongs on the Marketing Team?
You know the promises: GPTs generate copy in seconds, analyze data, and brainstorm campaign ideas. Sounds like every marketing team’s dream. But be careful—there’s a lot of human responsibility that lies between potential and reality.
In this article, we’ll show you how to use GPTs productively—and where it’s better to take the reins yourself.
What GPTs are already good at today.
GPTs can lighten your marketing team’s load—if you use them wisely:
-
Developing content ideas: Headlines, outlines, variations—GPT delivers on command. Ideal for brainstorming.
-
Supporting SEO optimization: Clustering keyword sets, crafting meta descriptions—perfect for routine tasks.
-
Personalized outreach emails: With good prompt writing, you can create smart, high-converting templates.
-
Transcripts & summaries: A real efficiency booster for meetings, interviews, or webinars.
💡 GPTs are particularly strong at generating ideas, writing text, and handling repetitive tasks. They boost efficiency but don’t replace strategic thinking.
But: GPTs hallucinate—and they do so damn convincingly.
It sounds weird, but it’s an everyday occurrence: GPTs invent sources, “make up” study results, or misquote sources. They sound so plausible that it’s easy to fall for them.
What does this mean for you?
-
Fact-checking is a must. Always. GPT is no substitute for a research tool.
-
Don’t enter any sensitive data. The GDPR says so.
-
Spot GPT bullshit. Critical thinking remains your most important tool.
🔎 Want an example? Ask GPT for the latest HubSpot statistics—it’ll give you some. But here’s the thing: they often don’t exist. So please always double-check and rely on real sources.
There are things GPT can’t (and shouldn’t) do (yet)
As powerful as GPTs are—their limitations are real:
-
Positioning and brand management: GPT doesn’t know your strategy. And it doesn’t understand your brand.
-
Creative campaign ideas with a twist: Without cultural insight, GPT often remains generic.
-
Subtle copy with a distinct voice: No algorithm can (yet) deliver empathy and a genuine voice.
💡 GPTs can’t make strategic decisions, convey brand identity, or evoke genuine emotions. Human creativity remains irreplaceable.
Our 5 GPT Commandments for Marketing Teams
-
Use GPT as a co-pilot, not as autopilot.
-
Prompting is an art. The clearer the input, the better the output.
-
Test, measure, optimize. GPT doesn’t learn—but you can learn from it.
-
Take responsibility— including for legal risks.
-
Get your team up to speed on GPT. Training is a must, not an option.
-> GPTs are brilliant—if you know what you’re doing
Those who use GPTs blindly may save time—but risk quality and credibility. Those who integrate them wisely gain a powerful tool for their team. And that’s exactly where the opportunity lies for forward-thinking marketing teams.
