How to show essential characteristics in Email template

Hi ,
I wonder how it could be possible to show essential characteristics in an email template?

I have implemented something like this for the productlisting with a subscriber which adds an extension like this:

            $featureSet = $productEntity->getFeatureSet();
            if ($featureSet != null){
                $features = $featureSet->getFeatures();
                foreach ($features as $feature){
                    $featureId = $feature['id'];
                    $featureName = $feature['name'];

                    if ($featureName == "manufacturerNumber") {
                        array_push($extensionData[$productId],array(
                            "featureName" => "Product Number",
                            "featureValue" => $productEntity->getProductNumber(),
                        ));
                    }
                   
                    foreach ($productProperties as $property ){
                        $propertyId = $property->getGroupId();
                        $propertyName = $property->getname();
                       
                        if ($featureId == $propertyId){
                            array_push($extensionData[$productId],array(
                                "featureName" => $featureName,
                                "featureValue" => $propertyName,
                            ));
                        }
                    }    
                }   
            }

Would it be for an email template something similar, and, if yes, which event to subcribe?
Thanks for your feedback…
