Customer data is the foundation of modern sales and marketing, but most businesses are sitting on a goldmine they don’t fully understand. While many teams collect names and email addresses, they’re missing the deeper insights that actually drive revenue: behavioral patterns, customer intent, and real-world feedback.
The numbers tell a powerful story. 81% of customers expect personalized experiences, yet 24% of CRM admins report that less than half of their data is even accurate and complete. Meanwhile, poor data quality costs organizations at least 20% of their annual revenue.
The good news? Understanding your four core data types and centralizing them in one place can transform how you sell, market, and support your customers. Let’s break down exactly what customer data types matter and how to collect them the right way.
Understand the Four Core Data Types: B2B teams should leverage identity, interaction, behavioral, and attitudinal data to build complete customer profiles and tailor their outreach effectively.
Activate Data Across Teams: Marketing, sales, and support can each use different data types—like behavioral trends for targeting or feedback insights for product refinement—to improve engagement and outcomes.
Centralize and Segment: Using a CRM to unify customer data enables smarter segmentation, personalization, and campaign automation that drives higher conversion and retention.

Customer data, or customer information, is a collection of statistics that answer questions such as:
This information and more can be found through the collection of different types of customer data.
Customer data itself can come from different sources: zero-party data is information voluntarily shared by the customer themselves; first-party data is information collected directly from the customer via the company’s interactions with them; and third-party data is purchased from external databases that access the data on a company’s behalf. Each of these data sources can be beneficial in their own contexts and scenarios.

To successfully market and run your business, you’ve got to know your audience.By collecting customer data, you can gain better insight into your audience to create more informed marketing campaigns that appeal to your target audience and drive more revenue for your business.
By collecting customer data, you can gain better insight into your audience to create more informed marketing campaigns that appeal to your target audience and drive more revenue for your business. But here’s what makes data truly powerful: when it’s organized, accurate, and accessible.
The numbers tell a clear story. According to a 2024 study of 631 CRM professionals, poor data quality costs organizations at least 20% of their annual revenue – equivalent to hundreds of thousands or millions of dollars depending on company size. Meanwhile, companies using segmented campaigns achieve 50% higher conversion rates, and customer segmentation drives a 33% increase in customer lifetime value. The difference between scattered, incomplete data and centralized, clean data isn’t just about better reports – it’s about leaving money on the table or capturing it.
Consider this: A regional real estate brokerage was running four different marketing channels but couldn’t connect the dots between spending and closings. Once they unified their customer data and understood attribution, they discovered direct mail was their highest-ROI channel by far. That insight alone allowed them to reallocate budget and increase revenue. That’s the power of understanding and organizing your customer data.
Consider how Kodak’s data blindness cost its empire. In 1975, Kodak’s own engineer, Steven Sasson, invented the first digital camera, complete with a CCD sensor and cassette storage—but the company chose not to pursue it. Leadership feared that digital imaging would cannibalize Kodak’s highly profitable film business.
Despite extensive internal research confirming digital’s potential, Kodak downplayed these insights to protect its legacy data model centered around film and chemical sales. Meanwhile, competitors like Canon, Nikon, and later smartphone manufacturers surged ahead, capitalizing on consumer demand for digital photography.
By the late 1990s and early 2000s, Kodak was being left behind—even though it held the patent for the technology. The company ultimately filed for bankruptcy in 2012, having failed to align its data strategy—its customer and market insights—with its core operations.
This story vividly illustrates that collecting customer or market data is not enough—teams must properly interpret and strategically act on it. When data collection methods don’t empower stakeholders to make timely, aligned decisions, businesses risk obsolescence.
There are four main types of customer data to look out for. Each of these types of customer data brings value to your business and shouldn’t be overlooked. Read on to learn more about these four types, as well as some examples of customer data and tips on how you can start collecting them today.
Basic, or identity data, is just that—it’s the basic information you gather from customers that identifies them as unique individuals.
Basic customer data includes a customer’s:
Other types of basic customer data include things like a customer’s work industry and occupation, income, IP address, and social media handles.
Basic customer data is useful for businesses and marketers because it helps to create buyer personas and get a clearer picture of the demographics your business is appealing to.
Collecting basic customer data or customer information is possible through the forms your customers fill out on your website, like newsletter subscriptions, contact forms, account sign-ups, and purchases.
With customer database platforms or customer relationship management (CRM) systems like Nutshell, you can collect, organize, store, and centralize all your customer’s unique identity data for quick and easy access and analysis at any time.
Interaction, or engagement data, refers to customer data related to how your customers interact with your business across various touchpoints. Rather than looking at your audience members individually, engagement data looks at your audience as a whole.
Customer interaction data comes in the form of:
This customer data also comes from product or service information like customer purchasing habits and overall popularity.
Customer interaction data is important for understanding the attitudes and habits of your target audience. With it, you can create well-informed marketing campaigns that better appeal to your audience.
You can collect customer interaction data in a few different ways. The first is by looking at your website’s analytics page. There you can find customer information like views, CTR, and bounce rate. From your website’s analytics, you can also find interaction data related to your products and services.
You can also collect customer interaction data from your paid marketing and social media campaigns. Social media platforms that allow advertising include post analytics, so you can see exactly who liked your post, where they’re using the platform, and how often your post or ad was seen by users.
When you run campaigns like paid search ads, you’ll have access to reports and analytics dashboards that give you the rundown on how well your ads are performing. You see everything from the number of clicks your ads earned to where your ads appeared.
With Nutshell, you can analyze all your customer interaction data to see exactly how your leads interact with your website, social media posts, and team members.
Behavioral customer data is similar to customer interaction data but a little more defined. Behavioral data looks at a customer’s direct engagement with your business. Depending on the industry you’re in, interaction and behavioral data can sometimes be combined.
Behavioral customer data includes:
Like customer interaction data, you can collect behavioral data straight from your website by looking at transactional information for products and individual user behavior.
You can also look at email interactions to collect behavioral data like newsletter subscribers and unsubscribes.
You don’t have to sift through all this data alone, though. With Nutshell, you can track how your leads are moving through your pipeline. You’ll see everything from where leads drop in (and out) of your sales funnel, the products they purchase, and their purchase history.
Last but not least is attitudinal data. Attitudinal data is comprised of first-hand opinions from customers on your business, services, and products. Unlike the previous three types of customer data, attitudinal data is a bit harder to process.
Basic, interaction, and behavioral data include hard numbers that can’t really be disputed—these data points are clearly stated for you to interpret. Attitudinal data, on the other hand, is a bit different.
Rather than numbers, attitudinal data consists of:
Attitudinal data is a bit trickier to process because not every review is written the same. Some customers may be extremely detailed with their reviews and survey responses, while others keep it short and to the point.
As a business owner, marketer, or customer service representative, it’s your job to extract the important customer information from these customer reviews and feedback responses and turn them into valuable, actionable data.
As you can probably guess, attitudinal data is collected from the surveys and feedback forms you send out to your customers. You can also extract attitudinal data from the interactions you have with your customers when you work with them in your store or business.
While attitudinal data doesn’t really involve specific data points like other customer-related data types, it’s still just as important to collect and analyze. Don’t be afraid to ask your customers and clients for feedback. Not only does it inform you of people’s opinions of your brand, but it helps identify areas of improvement.
Nutshell’s CRM features a Form Builder tool so you can create and distribute them for data and feedback collection. You can also leverage Nutshell’s email automation to send emails to customers asking them to fill out a survey, leave a review, or add any other feedback on their experience.

Effectively leveraging the customer data you collect through customer database platforms and other tools, you can significantly enhance your marketing strategies, customer support, and overall business decisions. Consider some of the best ways you can use your customer data:
Use behavioral and interaction data (site visits, email engagement, content consumption) to see what’s working right now, not just last quarter. Look for patterns by channel, campaign, and segment, then reallocate budget and effort toward the tactics that move prospects to the next step in your funnel.
It’s important to tie these insights back to measurable outcomes. For example, if certain pages or emails correspond to more closed-won leads, prioritize those topics in ads, nurture sequences, and sales enablement. The goal is to shorten the path to purchase by doubling down on the behaviors that signal intent.
Build campaigns around what customers actually care about—use attitudinal data (preferences, goals, pain points) alongside firmographic or demographic fields. Start with a few high‑impact personalizations (industry, use case, role) and reflect them in headlines, value props, and proof points.
Keep personalization practical and scalable. Create dynamic audience lists and let your CRM or marketing automation pull the right message for each contact. This avoids one‑off creative and keeps your team focused on performance.
Segment on the signals that change buying behavior: lifecycle stage, product interest, deal size, or engagement level. Then tailor both language and incentive—e.g., ROI calculators and case studies for evaluators, quick‑start bundles and onboarding offers for buyers ready to act.
Then refine your segments continuously. As contacts interact with your site, emails, and sales team, update segment membership automatically so that messaging always matches where they are today, not where they were when they first converted.
Use interaction data (tickets, webchat transcripts, knowledge base views) to route issues to the right person and surface likely fixes fast. Combine it with attitudinal data (NPS, CSAT comments) to understand urgency and sentiment, so agents can prioritize and respond with the right tone and depth.
Close the loop by training your AI-powered chatbot on recommended help articles and known resolutions, so you can provide targeted and effective solutions directly in your support workflows. When common issues spike, trigger proactive outreach or in‑app guidance to reduce time‑to‑resolution and prevent repeat contacts.
Don’t wait for a ticket—monitor product usage and engagement signals that predict friction (drops in logins, failed actions, uncompleted onboarding steps). When thresholds are met, alert your team or trigger an automated check‑in with targeted tips.
Follow up with human touch for high‑value accounts. Proactive, context‑rich outreach—“we noticed X and here’s how to fix it”—turns potential churn moments into trust‑building experiences and long‑term loyalty.
Turn qualitative feedback into structured data you can act on. Tag NPS/CSAT comments, surveys, and interview notes by theme (feature requests, onboarding clarity, pricing friction) and trend them over time to spot what to build, simplify, or document next.
Then you can share these insights across teams. Product can prioritize roadmap items with the highest customer impact, marketing can position around proven value, and success can update playbooks—so every improvement is grounded in clear, repeated customer signals.
Bring identity, behavioral, interaction, and attitudinal data together in one place to guide planning and forecasting. A unified view lets you see which segments grow fastest, which channels produce the healthiest pipeline, and which experiences drive repeat purchase.
Use these insights to align teams on a single operating plan. Budgeting, capacity planning, and roadmap choices become easier—and more defensible—when they’re tied to live customer data rather than assumptions.
AI adoption in CRM is accelerating. Between 2025 and 2030, AI and big data adoption is expected to increase by 97%, , and 46% of CRM admins are already using AI features. But here’s the catch: 67% of organizations express concern about whether their data is actually ready for AI applications. The teams winning in 2025 are those prioritizing data quality before implementing AI tools, not after.
Personalization has moved from “nice-to-have” to table stakes. 81% of customers now expect personalized experiences, and companies using segmented campaigns see 50% higher conversion rates. In 2025, the question isn’t whether you personalize – it’s whether you do it in real-time across all channels.
As of January 2026, 19 U.S. states have enacted comprehensive privacy laws, and compliance requirements continue to evolve. Teams that treat data governance as a strategic priority – not an afterthought – are positioning themselves to compete without friction. Consent management, data retention policies, and transparent data practices are no longer optional.
Organizations are moving away from fragmented systems toward unified customer views. A unified approach enables faster personalization, better insights, and stronger customer relationships. Companies that centralize their data are seeing measurable improvements in customer lifetime value, retention, and revenue.
Manual data cleanup is becoming a relic. Leading organizations are adopting AI-enhanced data governance tools that detect anomalies, flag outdated records, and maintain data quality automatically. This frees teams to focus on strategy rather than data janitoring.
Collecting customer data isn’t a checkbox. It’s an ongoing process. Markets change, customer preferences shift, and data decays over time. Teams that succeed view data management as continuous improvement, not a project to complete.
Not all customer data is equally valuable or reliable. Zero-party data (information customers willingly share) is often more accurate than third-party purchased lists. First-party data (what you collect directly) is more trustworthy than assumptions. Prioritize data sources based on accuracy and relevance to your business.
By the time poor data impacts your results, it’s already cost you. The teams that win proactively maintain data quality with required fields, validation rules, and regular audits. Prevention beats cleanup every time.
Customer data scattered across email platforms, spreadsheets, and disconnected tools creates blind spots. A unified CRM gives your entire team – sales, marketing, support – a single source of truth, eliminating confusion and missed opportunities.
Every data point you collect should serve a business goal. If you’re not going to use it, don’t collect it. This principle keeps your data lean, your systems fast, and your compliance burden manageable.
Collecting customer data is one thing, but managing it all is another. With Nutshell’s all-in-one CRM, though, it’s easy.

Looking for more about customer data? Check out the frequently asked questions below:
Usually yes—what you need depends on the channel and where your audience lives.
Here’s a tip: Store consent proofs (a copy of a form submission, timestamped SMS conversations) in your CRM alongside the contact record so your team can segment and automate compliantly.
Keep customer data only as long as it’s needed for the original purpose, then delete or anonymize it. GDPR doesn’t set a fixed timeframe; your retention period must align with the purpose you stated and be documented in a policy. If the purpose changes, update your notice (and gather consent where relevant). Implement automated reviews in your CRM (e.g., purge inactive leads after X months, archive closed‑won/closed‑lost deals after Y years) and log the action for auditability.
Zero‑party data is information a customer intentionally and proactively shares (e.g., preferences, intent)—it most often shows up as part of your “attitudinal” data. The key is that customers volunteer it (quizzes, preference centers, surveys), which makes it both privacy‑forward and highly accurate. You can store these fields on the contact record and use them for segmentation and personalized campaigns.
