Add a marketing consent checkbox to the course settings dialog. This checkbox will allow users to opt in to receive marketing messages related to the course they're taking. When a user consents, they'll be added to the appropriate Mailchimp mailing list for that course. We'll also sync metadata, such as course completion status, with Mailchimp according to our predefined schema.

• Consent checkbox

  • Add the consent checkbox to the bottom of the course settings dialog.
  • The checkbox should appear only if the course is configured with Mailchimp integration.
  • Each course might have a different mailing list, and multiple courses can share the same list.

• Mailchimp Integration

  • When a user consents, add them to the corresponding Mailchimp mailing list.
  • Sync the following data with Mailchimp:
    • User metadata: id, first name, last name, and whether they've completed the course.
    • Course Information: course language group id, course id, and course language identifier.
  • If a user updates their email in our system, update their email in Mailchimp using their user id.
  • Detect if a user unsubscribes through Mailchimp via the Mailchimp API and update their consent status in our database accordingly.

• Managing Marketing Consent

  • Users should be able to edit their consent preferences by opening the course settings dialog again.
  • Ensure any changes in consent are reflected both in our database and Mailchimp.

• Background Sync Process

  • Implement a background thread to handle all synchronization between our system and Mailchimp.
  • This process should sync continuously, like chatbot_syncer in our codebase.

• Metadata and Schema Management

  • After attaching a Mailchimp list to a course, automatically set up the required metadata schema in Mailchimp. Use the same background thread you use for syncing users.
  • Remove any extra columns or fields in the Mailchimp list that aren't defined in our schema to make it clear which columns are supported and which are not. (People may add stuff there, which can lead to confusion for future users.)
