4 tipos de dados de clientes e como recolhê-los

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.

Key takeaways

  1. 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.

  2. 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.

  3. 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 FAQs

Looking for more about customer data? Check out the frequently asked questions below:

  • Do I need consent to collect and use customer data for marketing?

    Usually yes—what you need depends on the channel and where your audience lives.

    • Email (U.S.): CAN‑SPAM is an opt‑out law (consent isn’t required before sending), but you must include an unsubscribe and honor it promptly. Opt‑in is still best practice for deliverability and trust. 
    • SMS (U.S.): Marketing texts require prior express written consent; as of Jan 27, 2025, the Federal Communications Commission’s “one‑to‑one” consent rule also applies—consent must name each seller sending texts. To comply, keep timestamped records. 
    • EU/UK: If you rely on consent under GDPR, it must be freely given, specific, informed, and unambiguous, captured via a clear affirmative action (no pre‑checked boxes). Double opt‑in isn’t required by GDPR, but it’s often recommended.

    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.

  • How long should we retain customer data?

    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.

  • What is zero‑party data?

    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.

  • How can small teams keep CRM data “clean” without a data engineer?

    • Adopt a lightweight data‑quality checklist and automate what you can in your CRM. Schedule quarterly de‑dupes and bounce‑back reviews, and trigger email automations to reconfirm key details (role, location) when engagement drops.
    • Anchor to six common data‑quality dimensions—accuracy, completeness, consistency, validity, uniqueness, and timeliness—and tie one maintenance habit to each (e.g., required fields for completeness, format rules for validity, de‑dupe jobs for uniqueness, and stale‑record alerts for timeliness).
    • Use required/validated fields and dropdowns in your web forms, plus required fields in your CRM, to prevent bad data at the source.
