Artificial intelligence (AI) in digital marketing: what it is, uses and examples
How it helps you personalize, automate and measure your campaigns better
Artificial Intelligence in digital marketing refers to the integration of intelligent technologies – such as machine learning algorithms and advanced automation – into marketing strategies and actions.
In other words, it means harnessing machines’ ability to analyze large volumes of data, extract insights and make decisions (or recommend the best ones) with minimal human intervention, in order to improve and optimize marketing campaigns.
Thanks to AI, companies can personalize the user experience, predict buying behavior, automate repetitive tasks and communicate more effectively with their audience.
It is one of the most revolutionary trends of recent years in the digital world.
Why is AI important in marketing today?
Currently, AI applied to marketing has become so relevant that most organizations and marketers are adopting it quickly.
In fact, according to a SurveyMonkey survey reported by MarTech in April 2025, 88% of marketers use AI in their work.
The proliferation of AI-based tools (from Big Data platforms to virtual assistants) means that even small and medium-sized businesses can access these technologies to boost their results.
A key driver of this popularity has been the arrival of generative AI, and models like ChatGPT in particular.
To give you an idea of its impact: ChatGPT reached 100 million users in just two months after its launch (according to a 2023 UBS study), something unprecedented in the history of technology.
This meteoric growth shows the massive interest in artificial intelligence applications.
The benefits of adopting AI in marketing explain this trend
Intelligent automation can make campaigns more effective and efficient.
For example, AI makes it possible to analyze the behavior of millions of users to detect patterns that would be impossible to spot manually, segment audiences with pinpoint precision and anticipate what kind of content or product each person may be interested in.
This translates into more personalized experiences, more satisfied customers and a higher return on investment in marketing actions.
Consumers respond better when they receive the right message at the right time—something in which AI far surpasses traditional “one-size-fits-all” marketing.
Practical applications of AI in digital marketing
Artificial Intelligence has multiple practical applications in the marketing field.
Below, we summarize some of the most important and common ones today, with concrete examples of how they are used:
| Use | Example | Type of tool |
|---|---|---|
| Personalization | Product recommendations in an online store | Recommendation engines |
| Email marketing | Suggested subject lines and copy, behavior-based segments | Email marketing platforms with AI |
| Customer service | Answers to frequently asked questions at any time | Chatbots |
| Predictive analytics | Which customers may unsubscribe or buy | Analytics and CRM tools |
| Advertising | Automated bidding and audiences | Ad platforms |
| Content | Copy and image drafts | Generative AI |

Personalized content and offers
As we mentioned, AI can analyze behavioral data and preferences to show each user content tailored to them.
For example, streaming services like Netflix and online stores like Amazon use intelligent algorithms to recommend products or content based on your past habits.
In marketing, this means sending personalized offers by email or showing ads tailored to each potential customer’s individual interests, significantly increasing the chances of conversion.
Imagine receiving a marketing email with product recommendations you’re actually interested in: that’s the magic of AI working behind the scenes.
Campaign automation and email marketing
AI has revolutionized the way campaigns are run, especially in channels like email.
Today it’s possible to fully automate email marketing so that subscribers receive messages at the optimal moment based on their behavior.
For example, you can schedule email sequences (drip campaigns) that are triggered by user actions (opening an email, clicking a link, abandoning a shopping cart, etc.), using algorithms that optimize send times and content.
In addition, AI tools generate compelling email subject lines (Mailrelay’s editor also helps you write them) and even personalize parts of the message for each recipient.
All of this improves open and click rates. We cover it in detail in how to use AI in email marketing.
Chatbots and 24/7 customer service
You’ve probably seen those virtual assistants on websites that chat with you.
AI powers many of them.
Smart chatbots can handle frequently asked questions, qualify leads and even help with sales, simulating almost human conversations.
On social networks and messaging apps, these bots provide customer support around the clock without requiring a human agent.
For example, banks answering balance inquiries or shops giving product advice via WhatsApp use conversational AI (Natural Language Processing) to understand questions and give helpful answers.
This improves user experience (they get immediate answers) and frees up human teams to solve more complex cases.
Predictive analytics and advanced segmentation
Predictive AI analyzes historical data and real-time data to predict future behavior.
In marketing, this is used for lead scoring (anticipating which prospects are most likely to become customers), for sales forecasting or to detect when a customer might leave so you can act in time (what’s known as churn prediction).
Likewise, using smart clustering techniques, AI can create highly precise audience segments, grouping consumers with similar patterns that may not have been obvious.
For example, an e-commerce company might use an algorithm to discover that one group of customers shops only during end-of-month promotions and responds best to limited-time discount messages, while another group prioritizes exclusivity over price.
With that data, differentiated campaigns are created for each segment, maximizing the impact on each one.
Online advertising optimization (AdTech)
In digital advertising (like Google Ads, Facebook Ads, etc.), AI plays a huge role in optimizing every euro invested.
Machine learning algorithms automatically adjust bids in real-time auctions to obtain better positions at the lowest possible cost (known as Real Time Bidding, part of programmatic advertising).
Similarly, advertising platforms use AI to display ads only to people who are most likely to be interested, relying on predictive models built from millions of browsing data points.
The result: more profitable PPC campaigns with better targeting.
For example, Google Ads offers smart bidding which uses AI to decide when to show your ad and to which user in order to meet the goal you set (whether conversions, clicks, impressions, etc.), automatically learning and improving over time.
Creative content generation
Generative AI has opened the door to creating texts, images and even videos automatically.
While human creativity remains irreplaceable, tools like ChatGPT, Gemini or Claude can draft articles, product descriptions or social media posts in seconds.
Likewise, there are AIs that generate images from descriptions (like DALL-E or Midjourney), which can be useful for producing visual content when graphic resources are lacking.
In content marketing, these tools accelerate production, allowing creators to focus more on strategy and less on the mechanical tasks of writing or initial design.
A practical example is using AI to suggest several blog titles optimized for SEO, or to automatically adapt a piece of content to different formats (for example, summarizing a long article into a TikTok script).
How to start using AI in your marketing
You don’t need to change everything at once. These five steps help you get started with little risk:
- Pick a task that takes up your time: writing subject lines, summarizing data or answering frequently asked questions.
- Try a tool on a small use case, not on your whole strategy at once.
- Always review what it generates: AI makes mistakes and doesn’t know your business the way you do.
- Measure the results with an A/B test against what you were doing before.
- Protect your data: don’t share your customers’ personal data with tools that don’t comply with the GDPR.
Once you’ve mastered the basics, you can take the leap to an AI agent that completes entire tasks for you.
Trends and the future of AI in marketing
AI in marketing is far from slowing down—it continues to evolve at a rapid pace.
New applications and improvements emerge every year.
For example, AI plays an increasingly important role now that less third-party cookie data is available (Safari and Firefox block them and many users reject them), helping brands understand their audiences through contextual analysis and first-party data.
We’ll also see greater integration of AI into marketers’ everyday tools: from CRM suites to web analytics platforms, they will incorporate smart modules that recommend actions (for example, suggesting which campaign to launch based on the latest data, or which email subject line might work best on a given day of the week).
Another rising trend is ethical and transparent AI.
Since the use of data and automated algorithms can raise concerns (privacy, algorithmic bias, etc.), companies are focusing on implementing artificial intelligence responsibly.
This includes being transparent with users when they’re interacting with a bot instead of a person, using anonymized data and making sure models don’t discriminate or make serious mistakes.
Public trust will be key for AI-driven marketing initiatives to gain acceptance.
One of those trends is already here: assistants that work directly with your tools thanks to MCP (Model Context Protocol). With it, ChatGPT or Claude can check your campaign statistics or prepare a draft in your email marketing account, always with the permissions you give them.
