Hi there @Kelly,

Welcome to the Community and thanks for posting your question here regarding a Fenix integration.

Currently, Klaviyo does not natively support a Fenix integration. In case you are considering any other integrated apps, Klaviyo has integrations with Aftership and ShipStation, so I would explore these options further. For your specific goal about displaying an expected next delivery date, you could include standard text of "normal delivery time is __ days", but you could not display a date that is in the future, unless that date is coming directly from an event property.  If you're using a Klaviyo flow to send the email you have access to any information that comes through with the event.  You just have to find the variables to use through the Preview menu.  You can click on the item you want to use and it will show the correct variable.  You can see our guide on this here!

If you are looking for another method that suits you better than those previously mentioned, I would recommend taking a look into our Track API to pull data with a custom event.

Hope this helped!
Alex
