How would I know the day it starts?
- Feder reads the new profiles Klaviyo records each day and compares each day with your own history.
- When new profiles go quiet or fall outside your usual range, Feder tells you.
Some numbers are too quiet to judge daily, such as a form filled in a few times a week. Until there is enough of your own history to judge a change, Feder says it is still learning and scores nothing, rather than guessing.
See what Feder reads from Klaviyo, which feeds Interest. Feder only reads. It never changes anything in Klaviyo.
