How To Upload Lists

Uploading User Data with the List Importer

Cortex's list upload feature allows you to import new users with specific user properties, as well as update existing users' information. This is perfect for marking groups of users with a specific registration source or location, or bulk-unsubscribing a list of users. It will match based on email address and add or update user information where you include it.  

Let's get started!

Step 1: Amend Your File

Before diving into Cortex, the spreadsheet must be reformatted with only the data that can be imported. This will involve deleting columns and renaming headers as you can see in the examples below. The following are the accepted column headers:

• email
• account_created_on (YYYY-MM-DD format required)
• date_unsubscribed (YYYY-MM-DD format required, any date will unsubscribe the user)
• full_name
• address1
• address2
• city
• state
• zip
• country
• phone
• birthday
• gender
• registration_source
• ip_address

Please note that the headers must be lowercase.

Step 2: Save Your Spreadsheet

• It must be saved in the proper file type, .csv or .txt.
• The format of the date must be re-formatted to YYYY-MM-DD if any edits are made after it's been saved as a .csv or .txt and not uploaded to Cortex.

Step 3: Upload Your Spreadsheet

• Now that the spreadsheet is ready, go to your Cortex admin to upload the list.
• Go to the Smart Segments page from the menu on the home page. It will be under the Audience section of the menu.
• Scroll down to Your Segments section and select Upload.
• Now you'll be in the New List page where the list can be named and the .csv uploaded.
• Alternatively, you can copy and paste the data from your excel sheet if it is a short list.

• Use the formula =CONCATENATE(col1," ",col2) to combine your first and last name columns with a space between them or see: How to merge First Name and Last Name to full_name.
• You can use the upload feature to mass unsubscribe users. Simply update the column header "date_unsubscribed" with the date you wish their unsubscribe status to begin (any date will unsubscribe the user). Please remember to use the YYYY-MM-DD format. More info here.

Things To Note:

• Wait for your list to finish uploading and processing before creating a campaign, experiment, or smart segment that references your new list.
• If you upload a user that is not in your database, their account created date will be the date of the upload and they will be eligible to receive New To Your Brand and other acquisition stage messaging beginning 48 hours after the account created date.
