Import Subscriber

In Salesforce Marketing Cloud, how do I import Subscribers into a list?

  1. Create a spreadsheet with your list of subscribers, saving as either .txt or .csv. Include these columns:
    • First Name
    • Last Name
    • Subscriber Key
    • Email Address
  2. Make sure your list is prepared for import.
  3. Log into the Marketing Cloud.
  4. Navigate to Subscribers, and select Lists.

  5. Navigate to My Lists, and open your folder.
  6. Find the list to which you wish to add subscribers, and click to open it.
  7. Click Import. In the "Import Wizard" window that opens, click Next.
  8. Before you can send email in the Marketing Cloud, you need permission from the subscribers to do so. If you have permission, check I agree and click Next.

For each import, the system logs the following information:

  • The results of your import:
    • Name of your import file
    • ID of the list into which the subscribers were imported
    • Number of subscribers imported
    • Number of existing subscribers updated with new data
    • Number of records that were not imported
  • All data fields for each subscriber record that could not be imported, and the reason why the import was unsuccessful
