How Do Document Databases Work in Email Marketing?

Document databases store information in a way that is both human-readable and machine-readable. Each piece of data is stored as a document, which can contain nested structures, arrays, and various data types. In the context of email marketing, a document might look like this:
{
"email": "john.doe@example.com",
"name": "John Doe",
"subscription_status": "active",
"preferences": {
"frequency": "weekly",
"topics": ["tech", "business"]
},
"behavior": {
"last_opened": "2023-10-01",
"last_clicked": "2023-09-28"
}
}
This structure allows marketers to store complex and varied customer data in a single document, making it easier to retrieve and analyze.
