Contentful Personalization: Introducing a streamlined, enhanced experience

We're positively thrilled to share a major product update: Ninetailed is now Contentful Personalization, seamlessly integrated right in the very heart of Contentful. Get ready to unlock a streamlined experience where personalization, analytics, and experimentation come together in one place. Say goodbye to juggling multiple tools and hello to driving results faster, smarter, and at scale.

Everything you need to generate more revenue is inside Contentful

With Ninetailed now rebranded as Contentful Personalization, its web app has been merged into the Contentful environment you’re already familiar with, creating a single, streamlined experience.

This rebranding and migration mark a significant leap forward for anyone looking to unlock the full potential of personalized digital experiences and experiments. Now, everything you need to drive results faster and at scale is seamlessly embedded into your existing Contentful workflows.

With this update, the power of personalization, analytics, and experimentation is now right at your fingertips — within the Optimization tab inside the Contentful web app. Here, you’ll gain access to a suite of features that work together to help you build deeper connections with your audience and grow your revenue.

Everything you need to generate more revenue is inside Contentful

From powerful audience segmentation and testing capabilities to AI-suggested audiences and experiences, we’re continuing to make it easier than ever to deliver the right message to the right person, at the right time. And, with the all-new overview screen, you can stay in control and on top of your digital experience optimization strategies with insights that drive smarter and more impactful decisions.

Integrating Contentful Personalization into Contentful is not just part of the acquisition story. It’s also our commitment to enhancing your workflows and simplifying the way you deliver personalized experiences and experiments. No more juggling multiple tools — everything you need for personalization at scale and experimentation is now in one place, enabling you to move faster, create with confidence, and generate more revenue. 

This change is all about helping you achieve true personalization and experimentation at scale without complexity or obstacles to progress.

Continuous optimization with contextual, AI-suggested audiences and experiences

We’re taking personalization and experimentation to the next level with powerful, AI-powered features. Now, in General Availability, our advanced AI capabilities are designed to remove the guesswork from audience segmentation, personalization, and experimentation — making it easier for you to deliver results faster, smarter, and more effectively. 

  • Audience Suggestions: Audience Suggestions leverages the power of predictive analytics to unlock the potential of audience data, identifying high-value audience segments with precision. By analyzing existing audiences, behavioral traits, events, page views, and contextual data, Audience Suggestions uses AI to forecast potential new audience groups. This capability serves as the baseline for the development of highly tailored marketing strategies and personalized content delivery, fostering more profound engagement, improved conversion rates, and enhanced ROI.

  • Experience Suggestions: Experience Suggestions changes the digital experience optimization through the transformative capabilities of AI, providing actionable suggestions for content personalization and experimentation — eliminating the where and how to start problems. 

  • Variant Generation: Variant Generation leverages the current experience configuration (such as title and description), audience configuration, previously sent data points, and additional context like tone, voice, and personalization strategy to create meaningful content variants.

  • Knowledge Base: Knowledge Base is automatically populated using existing content from connected content sources. This ensures that the Knowledge Base includes relevant global context to inform all AI capabilities — making all the AI capabilities contextually aware. 

These features, including the newly introduced Multi-Armed Bandit — allowing you to distribute your traffic smartly — are designed to bring you closer to achieving continuous optimization like never before.

Smart traffic distribution enhances your ability to show the most relevant experiences to your audiences by optimizing decision-making in real time, reducing experimentation time, and ensuring your resources are focused on the strategies that deliver the best results. By intelligently balancing exploration and exploitation, it accelerates your path to uncovering what works. 

Continuous optimization with contextual, AI-suggested audiences and experiences

Together with AI-powered audience suggestions and personalized experiences, these capabilities enable you to strengthen audience connections, amplify engagement with the most impactful content, and drive meaningful conversions. All of this is seamlessly integrated into your workflows, empowering you to stay agile in a world where every detail matters.

Expand your personalization and experimentation beyond Contentful-powered content

The boundaries of personalization and experimentation just got redefined. Introducing Custom Flags, a new feature that lets you extend your personalization and optimization strategies beyond Contentful-powered content. This is more than just a feature — it’s a gateway to elevating personalized experiences and enabling feature experimentation across your entire digital ecosystem, empowering you to innovate in ways you never thought possible.

With Custom Flags, you can bring the same level of precision and creativity to personalization, feature experimentation, and optimization across: 

  • ecommerce platforms,

  • checkout flows,

  • and even systems like PIM, LMS, or email. 

Imagine tailoring the layout of a product detail page to match individual shopper preferences, experimenting with checkout flows to maximize conversions, or delivering relevant content through external channels. 

This feature marks an important step toward continuous optimization across channels, allowing you to optimize not only content but also the functionalities that define your digital touchpoints. Custom Flags put you in control, granting you the freedom to experiment, learn, and perfect every aspect of your audience’s interaction.

The message is simple: personalization doesn’t have to stop where Contentful ends. 

Generate higher ROI from your data investments by activating customer data in personalization

Last but not least, we’re excited to unveil new Customer Data Connectors from SAP Emarsys, Klaviyo, and Shopify, now available in Contentful Personalization. These customer data connections allow you to unlock the full potential of your customer data by activating it for personalization and experimentation at scale. Instead of letting valuable information sit idle, you can now seamlessly connect these systems and turn raw data into actionable, revenue-driving insights.

Imagine using customer data from Klaviyo to create highly targeted audience segments or leveraging Shopify’s ecommerce data to deliver personalized experiences. No matter where your data lives, moving it into Contentful Personalization ensures you can harness it to deliver meaningful, adaptive experiences across multiple touchpoints.

By breaking down data silos and centralizing key information within Contentful Personalization, you’ll not only maximize the ROI of your data investments but also create deeper, more impactful connections with your customers. These integrations are your gateway to smarter personalization — driving higher engagement, loyalty, and conversions with every interaction.
