The profiles section in MadKudu allows you to look up individual emails based on the MadKudu API. This section also provides you with more enrichment data points than the signals, which corresponds to the enrichment from MadKudu's partners.

Why does the score here differ from the score I see in my CRM?
This is because the profiles page displays the customer fit score and signals returned by MadKudu API, which is the same as the realtime scoring in your integration. If you have a batch model for your Customer Fit model, this means you are probably using enrichment from your CRM which can only be leveraged in batch scoring.
