Yes. Turning an email off on the System emails page only stops Sprwt's built-in email (and any Sprwt Emails flow that starts from that trigger) - both of those check whether the email is active before sending. The Klaviyo event is still pushed whenever the trigger happens, because Klaviyo only checks that the trigger is flagged as an event, not whether the email itself is enabled. This lets you replace a Sprwt email with your own Klaviyo flow: disable the Sprwt version, then build the flow in Klaviyo on the same metric.
