You will learn

Learn about the source ($source) profile property to better understand how your subscribers signed up. Klaviyo automatically assigns a $source property for profiles added using certain methods. For example, subscribing a profile through Klaviyo’s API uses the API source (-9), unless the request supplies a custom source. Manually subscribing a profile uses Manually Initiated (-6).

Certain integrations and subscribe methods are tracked using a number, rather than a text description. The chart below outlines what these numbers mean.

Using special $source values

When creating a segment or flow filter based on $source, you may need to use these numbers to identify the sources you’d like to include.

To use a source in a segment, start creating a segment with this definition: Properties about someone > $source > equals. In the Enter a value field, select or enter the value stored in the profile’s $source property. If the value is a negative number, include the minus sign. Use the table below to identify the source associated with that code.

To check a specific profile’s source, open their profile and go to Details. Under Custom properties, locate $source and read its value. Use that value in your $source-based segment or flow filter. You don’t need to edit the property to check it.

Note that the value set for $source on a profile is overwritten when profiles take actions that set this field. For example, submitting a form would update the existing $source value on the profile to reflect the form submission.

The table identifies subscribe and unsubscribe sources, but $source does not show a profile’s current consent status. For example, unsubscribing from email does not overwrite $source on an existing profile. Check the profile’s channel consent status to see whether they’re subscribed.
