When creating an HTML paste email in marketing cloud I have a problem with the physical mailing address. I pass the email via API with a REST call in which I pass the html in JSON.
In the Preview and Test section, Marketing Cloud returns an error saying that there is no a valid physical mailing address, even if it's present. The problem is in the text version of the email. If in the Edit Content section I click on the text version tab and then go back to the Code View, the problem disappears, but the code doesn't change.
