Hello, I am looking at the mailing API documentation and it doesn't appear that the preheader text is available. Is there any way to get the preheader text through the API that I might be missing? Thanks in advance.
Doesn't look like preheader information is included in a element within the JSON of either: GET /#account_id/mailings or GET /#account_id/mailings/#mailing_id. If you know what you're looking for, you might be able to strip it from the html_body element or the plaintext element. In my case, it's inserted just after the opening body tag within a hidden div in the HTML one, and is the first line in the plaintext element.
