First-Party Data

Data collected directly from your audience through your own channels, including email engagement and preferences.

Definition

First-party data is information collected directly from your audience through channels you own and control. This includes email engagement data (opens, clicks), website behavior, purchase history, survey responses, and preference center selections. Unlike third-party data purchased from external sources, first-party data comes from direct relationships with your subscribers.

Why It Matters

First-party data is becoming increasingly valuable as privacy regulations tighten and third-party cookies disappear. It is more accurate, permission-based, and specific to your audience. Email is a primary source of first-party data - every open, click, and reply tells you about subscriber interests and behavior.

How It Works

You collect first-party data whenever subscribers interact with your brand. Email platforms track engagement automatically. Website tracking captures browsing behavior. Forms and preference centers gather explicit preferences. This data lives in your systems and can be used to personalize communications.

Best Practices

  • 1Build robust preference centers to gather explicit first-party data
  • 2Track email engagement to understand content preferences
  • 3Combine email data with website behavior for complete profiles
  • 4Keep first-party data clean and current
  • 5Respect privacy - collect only what you need and will use

Frequently Asked Questions

First-party data is inferred from behavior (what they clicked, bought, viewed). Zero-party data is explicitly shared by users (preferences, survey answers, stated interests). Both are valuable; zero-party is more explicit about intent.

Email is a rich first-party data source. Opens show interest. Clicks indicate preferences. Purchase data links to emails. Preference centers gather explicit preferences. This data personalizes future emails and other marketing.
