Introduction

A common question I get from marketers about AI, AI strategy, and agents revolves around agent interaction and autonomy. It looks something like this when marketers describe it:

• Campaign Strategy: I/my team relies on Claude Skills that are really interactive. For example, we find developing a complex campaign strategy works best if it is driven by a Claude Skill which has access to our broader marketing strategy, etc., but, it’s a back and forth process. The Skill jump-starts the process by generating a full strategy based on our basic campaign brief. Then, we go back and forth tuning many aspects of the strategy together. It takes many steps to get to the final strategy.

Compare that to a Campaign Performance Review Agent, which is much less interactive - more of a generate and then approve type of process:

• Campaign Performance Review: This agent is set up in Zapier. It references the full campaign strategy and plan, and the basic marketing program background information. The agent goes out daily to each campaign channel individually, retrieves the performance data to date, reviews, assesses and compiles a performance review for each channel. A master agent ingests the individual channel reviews, and creates a macro review and set of recommendations for campaign changes or A/B tests to improve campaign performance. This final review/recommendation is prepared and shared with the team on Slack each morning. The responsible team member reviews the recommendations, ok’s them (usually), and the next agent - the Campaign Tuner Agent - makes the necessary changes to the campaign in each channel.

Formalize the Framework

As part of a scalable marketing AI strategy, we step up from discussions about chatbots, Zapier, and interactivity, to a framework based on the distinguishing feature: Human-in-the-Loop (HITL) and agent autonomy. Here’s a closer look … I’m guessing you’re familiar with the term but let’s put it into practical context.

Human-in-the-Loop: In modern marketing, AI agency or autonomy (e.g. agent’s freedom to operate) naturally consolidates into two distinct types of agents: Checkpoint HITL and Collaborative HITL.

Early Agent Categorization. Defining early on which of these interaction models to use for each agent in your AI strategy/plan, ensures you design workflows that optimize the user experience, properly address brand risk, and align with the technical strengths of your software stack. In short, it ensures your agents perform well, and match the expectations of your team.

Checkpoint Agents

Checkpoint HITL Agents represent low-frequency, asynchronous interaction inside the workflow automations. In this model, an AI agent runs autonomously as multiple steps in the background - like the campaign performance reviewer agent: read the campaign strategy/plan, retrieve the performance data by channel, review and recommend updates for individual channels, aggregate reviews into one master review, share with the user, user reviews and approves the recommendations (the Human in the Loop at a defined point in the process), and the Campaign Tuner agent makes the updates.

Example Use Case. The interaction is intentionally lightweight and discrete: a marketer receives a notification, reviews the generated output, most often approves the recommendations, and clicks a simple button to approve or reject the action before the automation continues.

Zapier. This Checkpoint HITL architecture works great on no-code automation engines like Zapier. Zapier excels at managing serial step-wise execution of marketing workflows. Take, for example, working across multiple campaign channels (i.e. Google Search Ads, Facebook Ads, email, etc.), combined with native AI model calls to do the performance analysis and recommendation. And, because Zapier natively supports discrete human approval steps (i.e. Human in the Loop feature), interactive Slack buttons, and web form inputs, it serves as the ideal platform for this asynchronous review+approval with the team. There’s not a lot of back-and-forth, and limited interaction is best if you are using the Zapier platform.

OpenRouter. If you want full model portability, use Zapier in conjunction with OpenRouter to easily swap in and out AI models for each agent.

Collaborative Agents

Conversely, Collaborative HITL Agents are designed for high-frequency, synchronous co-creation where a human and an AI model iterate side-by-side in real time. An example, Campaign Strategy Development agent.

Application Areas. This mode is essential for applications like dense strategic positioning, creative copywriting, visual campaign ideation, and complex, dynamic problem-solving. Here, agent response time (low latency),  and context (state retention from one iteration to the next) are crucial. The agent and human go back and forth, and the agent keeps the context of the conversation at every step.

Agent Meets Human Needs. Human marketers require few-second response times, transparent response generation (the model tells me what it is doing), immediate feedback loops (easily handles rapid feedback from the human), and rich context memory to alter tone, explore creative directions, and refine assets back and forth effortlessly.

Agent Development. To achieve this interaction speed, context-retention, and transparency, agent design uses the Collaborative HITL model. These agents can be developed directly on frontier AI model platforms rather than on automation workflow platforms like Zapier. For example, within Anthropic’s platform, teams construct these collaborative agents by creating Claude Agent Skills (modular capabilities defined via SKILL.md instruction files), organizing shared domain knowledge in Claude Projects, and co-editing content within Artifacts. Within OpenAI’s environment, teams build tailored conversational agents using Custom GPTs built via GPT Builder.

Alternatives. If you want to avoid vendor lock-in to any one frontier AI platform for a Collaborative HITL model agent, try Gumloop for interactive workflow automations. More on this platform in a future post.

Conclusion

By mapping marketing agents to this dual-mode framework, you eliminate a lot of frustration when agents engage with users in the right way - lots of interaction vs. simple review and sign-off. That improves operational efficiency, and ensures agents produce the best output, too.

Zapier (and OpenRouter) handle agents where background, asynchronous processing works best (Checkpoint Agents), while frontier AI platforms tools like Claude Skills host low latency, many turn agents functioning as creative director or strategy lead (Collaborative Agents). Aligning your technology choices with these two distinct Agent interaction patterns ensures your marketing organization achieves scalable background automation without sacrificing real-time creative collaboration. And, both types of agents will exist within your AI strategic plan.
