Offline data is data collected and stored in “offline” systems, for example, CRM platforms, point-of-sale (POS) systems, email-marketing platforms, and contact-center applications. Ideally, it is tied to some form of personally identifiable information (PII) including but not limited to email address, name, postal address, or customer ID. Offline data can include first-party information, which is considered the most valuable, but also can include third-party information like demographics and buyer propensities.

The act of connecting offline data to online is called “data onboarding” or more recently “connectivity.” The most important principle to this process is privacy; by de-identifying PII in both offline and online data sets, data vendors can connect the dots but also protect the individual’s privacy and the brand’s integrity.

Offline Data Tactics

Data onboarding allows marketers to increase targeting efficiency and close the gaps within campaign measurement. Below are the key offline data tactics in practice today:


  • CRM Retargeting
  • Cross-channel Marketing
  • Ad Suppression
  • Look-alike Modeling


  • Closed-loop Measurement
  • Cross-channel Attribution

To ensure data onboarding success, there are three key characteristics to gauge when working with a match partner:

  • Match Rate–Measured as a % of the offline
    data matched to an online user, industry match
    rates currently fall between 30-55%
  • Accuracy–Measured based on how often the
    onboarding provider can correctly match offline
    data to an online user profile
  • Integration–Turnaround time is important, and,
    because cookies age, matching is an ongoing
