Sync Contact to Data Extension

Data extensions allow for adding and removing contacts during syncing, so it can be used to keep a segment in sync. However, the content will not be updated once a contact has been loaded into the Data Extension. This action is compatible with creating a Data Extension from within Simon and using it for multiple variants in an experiment.

Within Salesforce Marketing Cloud you can navigate to your data extension via Subscribers > Data Extensions.

Use Cases

  • Keeping a segment up to date (without keeping field values up to date).
  • Experiments with different variants using the same Data Extension


  • Subscriber Key must be set up as SubscriberKey (without a space) in the data extension in Exact Target to sync properly
  • All fields should be set up as Text Fields with length set to maximum (500 characters)
