We collect data from different sources i.E. Event registrations, whitepaper downloads, product configuration and save each source in a own Data Extension (user contact data + source specific data). We also ask in each source if the user want's to receive Newsletter and save it as a boolean field in each DE.
- Does is make sense to separate each data source as own DE, each entry has contact data as firstname and lastname saved, which is a lot of duplicate data
- How to transfer contact data (firstname, lastname) from multiple DE's to Contact Attributes?
- Is it a good way to manage the DOI through a Journey?
