Discover actionable insights from marketing experts who are already using AI to effectively localize their content.

Multilingual Marketing in the Age of AI

Artificial intelligence is reshaping global marketing, particularly in the realm of content localization. As the capabilities of AI expand, marketers need to make informed, strategic decisions about which tools to implement, how to deploy them effectively, and when to integrate human expertise.

To discuss these developments, we invited Nataly Kelly (CMO of Zapier), Beth Dunn (Head of Experience at Agent AI), and Lee Densmer (Founder of Globia Content), to share actionable insights based on their extensive expertise in global marketing.

The fascinating discussion, Rethinking Global Marketing AI, was moderated by Acolad’s Director of Global Marketing Services, Hinde Lamrani. You can watch the full webinar online.

So, let’s look at some of the traps to avoid when trying to make the most of AI for your global marketing.

Key Takeaways from this Article

Using the wrong type of AI tool, such as a generalist model for creative content, can lead to inefficiencies; selecting purpose-built tools is essential for effective marketing localization.
Achieving success with AI in marketing requires realistic expectations, structured data preparation, and clearly phased milestones to measure progress.
Human oversight is critical for ensuring cultural nuance, especially in localized content; AI alone cannot fully adapt brand messaging across diverse markets.
Authentic storytelling and proper content governance, including consistent prompts and clear brand guidelines, are essential for maximizing the value of generative AI.

Key AI Marketing Localization Mistakes to Avoid

Using Generalist Tools for Specialized Needs

Lee Densmer cautioned against misapplying tools, such as using an AI model that is designed for deep reasoning or coding for creative tasks, and to instead pick the right AI tool for your task. Beth added:“There can be frustration if you’re trying to apply a generalist tool for a specific purpose.”

Instead, it might be worth your time researching the best tool to suit your marketing tasks, for example, a tool designed to automate workflows, or a custom LLM model that might have been trained to perform better at creative content generation.

Expecting Immediate ROI

Beth reminded attendees that effective AI integration requires upfront work - building structured data, training models, and setting realistic expectations.

To address this, set phased milestones and measure incremental progress to build confidence and long-term value.

Ignoring Cultural Context

AI often lacks cultural nuance. As Lee noted, over-reliance on AI can flatten cultural differences, undermining localized messaging.

Where possible, ensure human reviewers with local expertise can assess content for cultural fit.

"It’s about the strategy, it’s about creating a style guide for that country. It’s about market research for that country. It’s about checking that the branding has made the jump from one culture to another in terms of nuance and relevance. It’s a lot more of a craft."

"You have to back up and say ‘here's the context, here's why we do things the way that we do.’ That's how I train people to prompt. I say, imagine you're onboarding a new hire."

Not Investing in Content Governance

Another key point is that content governance, such as clear guidelines, review process and brand tone documentation, will all help you get the most of generative AI. You can use this foundational content to train your AI much more effectively. Then your AI agents will be effectively customized to suit the needs of your organization.

As Hinde added: “Garbage in, garbage out.”

Not Making the Most of Marketing Data

A crucial part of AI skillsets often neglected by more creatively minded marketers is its capacity for large-scale data analysis. AI can help marketers anticipate behaviors and tailor content in real time, through audience segmentation to predictive analytics.

For example, Nataly shared how Zapier uses AI to analyze campaign performance across regions, before iterating quickly based on those insights.

Balancing Scale and Local Nuance

One major challenge in global marketing is finding the right balance between scalability and cultural relevance. As noted above, local human experts can be invaluable to ensuring your messages resonate effectively in diverse markets. And that’s great with limitless resources. But how do you do it effectively when under real-world constraints?

Describing Zappi’s approach to localization, Nataly shared how it can be harnessed as a growth strategy. Her team uses AI tools and identified market-specific trends and preferences to adapt messaging while keeping a coherent brand.

Their tiered approach means high-priority markets get more customized, human reviewed content, while lower-tier markets can benefit from AI-assisted translation and tone adaptation. For many businesses, AI has unlocked the ability to tailor and adapt messaging for lower-priority markets that would never have previously been possible. Obviously human might be better quality, but AI means you can adapt your approach to maximize your ROI.

Overcoming Institutional AI Hesitation

Many organizations are institutionally hesitant to adopt AI, and so it may be key to try to foster a culture of experimentation within teams.

“[It’s about] giving people the freedom to experiment, encouraging them, putting people through training. The culture of fun and experimentation.

Nataly added that patience and a strategic approach can be crucial to this process.

She said: “Having that ability to take a step back […] think what is it we’re trying o accomplish, how do we think it’s best to do that? Which solution or approach is going to work the best for us in terms of leveraging AI agents or whatever AI tool you’re using?”

"We have to take a step back and think, and that’s what humans are fortunately good at. If we give ourselves a little time and space, we can come up with a good strategy, but it can’t be so frantic. We need time and we need patience."

Helping Marketers Harness AI for Success

In conclusion, selecting the right AI tools for localized marketing is not just a technical decision - it’s a strategic one. As discussed in the webinar, marketers that really succeed with the help of AI are those that plan intentionally, invest in quality data, and still deploy the human touch when most relevant.

By leveraging AI tools as collaborators, marketing teams can deliver scalable content that feels authentically local and genuinely engaging. The marketers who will thrive in the AI era are those who combine the efficiency of AI with the nuance of human insight.
