What destination type is recommended for exporting a customer's email address and attributes to an SFTP connection?

When exporting customer data such as email addresses and associated attributes to an SFTP connection, the recommended destination type is file-based destinations. This method is ideal for handling bulk data exports, as it allows for the creation of files that can be securely transferred to an SFTP server.

File-based destinations enable users to define the format and structure of the exported data, ensuring compatibility with various systems. This makes it easier to format the data as needed and manage how it is stored on the SFTP server. Additionally, file-based destinations are typically designed to handle scheduled or on-demand exports, providing flexibility in how and when data is moved.

In contrast, other options like connectors are typically used for real-time integrations with platforms that require continuous data flow rather than batch exports. Extensions and streaming segment export destinations are focused on live data flows or targeted audiences and do not effectively serve the purpose of bulk file exports to an SFTP connection. Therefore, file-based destinations are specifically equipped to handle the task of exporting customer data securely and efficiently to an SFTP location.
