Generative AI: How this technology is changing marketing in 2025

Generative Artificial Intelligence (Generative AI) is no longer a futuristic promise reserved for tech companies. In 2025, it has become a core tool in marketing departments across all types of organizations, from regional startups to large multinational corporations. What began as an experimental curiosity now profoundly transforms how brands communicate, design campaigns, and build relationships with their audiences.

This transformation is deep and far-reaching—not just because it automates tasks or accelerates content production, but because it completely reshapes creative processes, audience segmentation, personalized experiences, and data-driven decision-making. Generative AI in 2025 digital marketing represents a real competitive advantage for those who know how to integrate it intelligently and ethically.

Understanding generative AI: More than just automation

Generative AI is a type of artificial intelligence capable of creating original content by learning from large volumes of data. Its main difference from other automation technologies is that it doesn’t just execute pre-designed tasks—it can imagine new solutions, generate text, images, videos, graphic assets, and even concepts, replicating human-like styles, tones, and structures with surprising naturalness.

This generative capacity is powered by advanced language models trained on millions of examples. The most well-known—such as GPT, Claude, or Gemini—not only answer questions but also develop ideas, write full articles, design entire campaigns, or suggest creative improvements based on a brief. In marketing, this helps eliminate bottlenecks, encourages experimentation, and allows for faster responses to shifts in consumer behavior.

New ways of doing marketing in the age of generative AI

One of the most obvious applications of this technology is content creation. Brands no longer rely solely on copywriters and designers for every asset. Now, AI can draft blog articles, social media posts, email subject lines, ad copy, and even video scripts, which are later refined by human teams. The result: higher content output, shorter development times, and more opportunities for testing and optimization.

But the benefits go much further. Generative AI also enables advanced personalization. Instead of sending the same message to the entire database, brands can automatically tailor content to different user profiles based on factors like location, browsing history, stated interests, or recent behavior. This significantly increases open rates, click-throughs, and conversions.

Another growing use case is creative automation. AI-powered tools can generate dozens of visual campaign variants in seconds, suggest alternative titles, test different messaging approaches, and even predict which creatives will perform best depending on the audience and channel. Creativity is no longer limited by time—it’s enhanced by new possibilities.

Simultaneously, data is no longer just for post-campaign analysis—it fuels real-time campaign generation. With predictive analytics, AI can identify emerging trends, detect high-potential microsegments, or suggest corrective actions when a campaign underperforms. In this way, strategy shifts from being a static document to a living, flexible, moment-adapted system.

Real-world adoption in Latin America

Across the region, various companies are making solid progress in integrating generative AI. For instance, Mercado Libre uses this technology to automatically enhance product descriptions in its marketplace, helping sellers stand out with SEO-optimized and more attractive content.

In Peru, Rimac Seguros has incorporated generative AI into its email marketing. Each message is automatically adapted to the client’s profile—age, inquiry history, purchased products, and potential needs. This personalization increased the campaign response rate by over 30%.

In Brazil, Natura combines generative AI with sentiment analysis to respond more empathetically and meaningfully to interactions on social media. This not only improves user experience but also strengthens the emotional bond with the brand.

These examples show that adoption isn’t limited to tech giants—it can be progressively implemented by companies in any sector that are willing to experiment, measure, and learn.

How to integrate generative AI into your strategy

For successful implementation, the first step is understanding that this technology doesn’t replace human talent—it enhances it. Rather than limiting creativity, it frees the team from repetitive tasks, allowing them to focus on strategic decisions, campaign ideation, and critical content review.

Ideally, start with a specific area. Some brands choose to automate product descriptions, others generate campaign variants for A/B testing, and some begin with social media posts. In all cases, it’s essential to define clear KPIs, compare results, and adjust the process accordingly.

Training is also critical. The more familiar teams are with these tools, the better the outcomes. Learning to write effective prompts, reviewing outputs with editorial judgment, and evaluating based on data are new skills that teams must adopt.

Finally, ethical considerations should never be overlooked. It’s essential to ensure transparency in the use of AI, avoid reinforcing biases, comply with privacy regulations, and maintain brand tone consistency. An AI tool can be highly efficient, but the final responsibility for the content will always rest with humans.

Augmented marketing: When technology fuels creativity

In this new landscape, campaigns are no longer thought of solely in terms of design and execution. Instead, they become intelligent systems that learn, adapt, and optimize in real-time. Generative AI in digital marketing allows a qualitative leap: reaching more people, with greater precision, in less time, and with stronger impact.

The key is not to replace human ingenuity, but to amplify it. Brands that understand this are laying the foundations of the marketing of the future: faster, more personalized, and deeply aligned with the real needs of their audiences.
