Data onboarding is the process of transferring offline unfamiliar data to an online environment for marketing purposes. This process is mainly used to connect offline customer records with online users by matching identifying information gathered from offline datasets to retrieve the same customers in an online platform.

While great analysis can be gathered from poorly structured data, onboarding data from outside sources can be a contradictory course of action. It can be done the right way but slowly or it can be done quickly with errors. In the former route, one can draw on the expertise of engineers or IT professionals while in the second route, it can be done yourself with not always the best tools.
