Turn off inform email and Klaviyo integration

Hi
We have done the API Integration to Klaviyo and want to disable the Inform Result email and send the results from Klaviyo.

1. How do we disable the email send from the plugin.
2. Are all the data fields like {customer_name}{coupon_code}{coupon_label} and {date_expires} sent to Klaviyo?

Under API we have linked to Klaviyo and the list was selected. The data is however not feeding into Klaviyo.

Thanks
