Step 1: Make your CSV file
Open Excel or Google Sheets.
Create a CSV file with two columns: identity,MSG-email (all lowercase).
Add each user’s unique identity in the first column, and write false in the second column to mark them as unsubscribed.
Example:
Download the CSV
Step 2: Go to CleverTap
Log in to CleverTap. From the left menu, go to Settings → Engage → CSV Uploads.
Click + Upload, then choose Upload user profiles.
Select your CSV file and click Save & Upload.
Step 3: Upload your CSV
After uploading, click Map next to your file.
Map identity → identity (this links to the user’s unique ID).
Map MSG-email → User Property and select True or False as the data type.
If MSG-email isn’t listed, choose “Same as column name” to create it.
Then click Process File to start the upload.
Step 4: Check your upload
Once processing is complete, go to Segments → Find People.
Search for one of the users from your CSV by their identity.
Open their profile and scroll to User Properties.
You should now see MSG-email = false listed, this means the user has been unsubscribed.
