Is an Email response considered an official document?

Can an email response, e.g. from the German Auswärtiges Amt, be considered an official document and used during travel?
As an example: If I have an electronic response stating that no special authorisation (Reisevollmacht) is needed for immigration or travel, can I use this if the airline asks me to show them a special authorisation (Reisevollmacht)
