SendEmail Is there a way to insert a Text or HTML Email Template at

The template field in the "Send E-mail" smart service is not an expression-able, you cannot use conditions to assign the template. Instead you could use a gateway (e.g. XOR) to direct the flow to a different send e-mail configured with the corresponding template. Assuming you have 3 languages, your model would need three different send e-mail nodes pointing to different templates; the decision of which one should be trigger would be delegated to the gateway not to the send e-mail activity.
