Hey there 👋

In 2000, a small online bookstore called Amazon realized manual recommendations would never scale to millions of customers.

The idea of personalizing suggestions for millions of shoppers was, frankly, absurd. So they built a system that did it automatically, learning from purchase history and browsing behaviour to surface the right book for the right reader at the right time.

It was one of the earliest examples of what we now call an autonomous marketing workflow.

At the time, most marketers called it "clever automation." Because what Amazon did with recommendations, agentic AI is now doing across the entire marketing function, from audience segmentation and campaign creation to real-time personalisation and performance analysis.

The transition to "AI as a system that acts" changes everything, including what humans are responsible for. Agents monitor, decide, and execute, which means your job now is to design better systems.

This issue is your guide to doing exactly that. 

Let's go! 🚀

Agentic AI, explained. Rewind a few years, and large language models and generative artificial intelligence were barely on the public radar. Today, attention has shifted to the next evolution of generative AI: AI agents or agentic AI, a new breed of AI systems that are semi- or fully autonomous and thus able to perceive, reason, and act on their own.

For the past three years, most marketers have used AI the same way they use a search engine: you ask it something, it responds, and you take that response and do something with it.

Agentic AI breaks this model.

An agent can perceive its environment (your analytics dashboard, your CRM, your inbox), reason about what needs to happen (a product launch is in four days, email engagement is dropping, a competitor just announced pricing), and take action (draft a campaign, update ad copy, reschedule a send), and then loop back and evaluate whether that action worked.

For marketers, this creates three fundamental shifts:

Before you build anything, you need to understand how agents actually work under the hood. Every agentic system has three layers, and your job as a marketer is to decide what sits in each one.

An agent is only as smart as the data it can read, so this layer defines your agent's "senses." 

For a marketing agent, that might include your website analytics, CRM data, social media engagement rates, competitor pricing pages, email open rates, and even your internal Notion docs or Slack messages.

Most out-of-the-box agents (HubSpot Breeze, Salesforce Agentforce) give you a predefined set of inputs. Custom-built agents via platforms like Relevance AI or n8n let you pipe in almost anything. The richer the inputs, the smarter the decisions, but the bigger the risk if the data is dirty or incomplete.

Your job here is to define what information the agent needs to do its job well, just don't give it everything; give it the right things.

This is the brain. The reasoning layer is where you encode your marketing strategy as logic that the agent can follow.

The campaign goal: traffic, leads, conversions, the brand voice, the budget ceiling, and what the agent should never do. 

In practice, this means writing a detailed system prompt (if you're using a Claude or GPT-powered agent), configuring decision trees, or setting up goal-scoring logic. This is where most agentic deployments fail because the reasoning layer was never clearly defined.

Think of it like onboarding a new team member: you wouldn't send them into a client call without explaining your positioning, your deal-breakers, and what winning looks like.

Your job here is to encode your strategy, not just your tasks. The agent needs to understand why, not just what.

This is where the agent interacts with the world: drafting an email and sending it, pausing a low-performing ad set, posting a social update, updating a lead score, or creating a Slack notification for your team.

The action layer is the most visible and the most consequential.

The critical design decision here is reversibility. Some actions are cheap to undo (drafting a post). Others are expensive or impossible (sending an email to 50,000 subscribers). Your agentic architecture should have very different human-oversight requirements for each.

A well-designed action layer includes confidence thresholds: if the agent is less than X% confident an action is right, it stops and escalates to a human rather than guessing.

Your job here is to classify every possible action by reversibility and risk and build confirmation gates for anything irreversible.

Here's how to build an autonomous content distribution and optimization workflow, one of the most common and highest-leverage use cases for agentic marketing.

The biggest mistake teams make is starting with "what AI tool should I use?"

Instead, start with "which workflow costs us the most time and follows the most predictable rules?"

Content distribution is ideal: you create a piece of long-form content, and the workflow for slicing it into short-form posts, scheduling them, and reporting on performance is almost entirely rule-based. That's your starting point.

Map it out completely before touching any software. Write down every step, every decision, every handoff. If you can't describe the workflow clearly, no agent can execute it reliably.

Before you configure anything, write a one-page brief for your agent. 

This brief becomes your system prompt, and the more specific you are here, the fewer times you'll have to babysit the agent later. Tools like Claude, Relevance AI, or a custom GPT let you paste this directly as a persistent system instruction.

Using n8n or Make, connect the data sources your agent needs to act intelligently. For a content workflow, that means your CMS (to detect when new content is published), your analytics platform (to read engagement on previous posts), and your social scheduling tool. 

Set up a webhook so the agent is triggered automatically when a new blog post goes live. This is what removes the human from the start of the loop.

Test this layer first with a dummy trigger. Make sure the data flowing in is clean, complete, and in a format your agent can parse. Garbage in, garbage out has never been truer than in agentic systems.

Decide in advance which actions require human approval and which can run automatically, as this is the most important step. 

A sensible starting matrix:

Build this routing into your workflow: after the agent drafts content, it should run each post through a risk-classification prompt ("Rate this post's sensitivity on a scale of 1–5 and explain why"). Posts scoring 3 or above go to a Slack channel for review; posts scoring 1–2 go straight to the scheduling queue. Your reviewer isn't looking at everything, just the things that actually need eyes.

An agent without a feedback loop is just a more expensive macro. 

At the end of each week, your workflow should automatically pull performance data on every piece of content the agent distributed, compare it against your benchmarks, and generate a plain-language summary: "Posts mentioning case studies outperformed category average by 34%. Posts published on Friday between 2–4 pm had 2x the engagement of Monday posts."

Feed this summary back into your system prompt on a rolling basis, or, better yet, build a lightweight "memory" layer using a tool like Mem or a simple Notion database.

Over time, the agent's outputs start to reflect what actually works for your specific audience, and this compounding effect is where the real advantage lies.

Agentic AI introduces failure patterns that simple AI tools never had, thus there’s a need to know them before you deploy.

You tell the agent its goal is to "maximize engagement," and the agent learns that outrage drives engagement. 

Without explicit guardrails, it starts to skew toward provocative content, technically meeting its goal while catastrophically missing yours. Always define what success is.

"Maximize engagement, but never post about politically divisive topics, never use fear-based framing, never reference competitor products negatively" is a much safer brief than "maximize engagement" alone.

In a linear workflow, mistakes are contained, but in an agentic workflow, one wrong decision at Step 2 gets baked into every subsequent step. 

An agent that misclassifies your audience segment on Monday might send the wrong message to 3,000 people by Thursday. Build checkpoints, such as short automated sanity checks that run every 24 hours, to flag anomalies before they compound into crises.

The most dangerous failure mode is the one where a human is technically "in the loop" but isn't actually exercising judgment. If your approval queue is 200 posts long and your reviewer has 10 minutes, they're rubber-stamping rather than reviewing. 

Design your oversight system so that the volume of items reaching a human is always reviewable in the time you have. 

Better to auto-approve more low-risk content than to create a fake checkpoint that provides no real protection.

Remember when Claude went down a few days back? Yeah, I think most of us do. It was worse than hitting your rate limit. 😆

There's a version of this transition that terrifies people: AI runs everything, nobody knows why, campaigns drift off-brand, and every Monday is a fire drill.

There's another version where your team spends its time on the things only humans can do: understanding what customers actually need, making judgment calls that no model can make, and designing systems smart enough to handle everything else.

The difference between the two versions lies in the intention you bring to the system's architecture.

The marketers who thrive will be the ones who built the best systems with clear goals, thoughtful guardrails, real feedback loops, and human judgment deployed exactly where it matters. 

It might be harder than writing prompts, but it’s much more interesting and impactful.

Until next time, keep exploring the horizon. 🌅
