What customer data is
There’s more to customer data than just names and emails. When it comes to customers interacting with your brand, be it through social media or browsing your website, you must understand the types of customer data you’re collecting and how you can leverage it for the benefit of your business.
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.

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.
