I just tried to update an email subject line via the API and got the following error:
"message": "API only allows operations on emails with a template"
I mean - it's pretty clear in the message itself - but I just wanted to double check that it wasn't possible to update anything in an email when it doesn't have a template. This would be quite annoying - we don't really use email templates in Marketo and instead create them in Dreamweaver, then copy the code in. So virtually none of our emails are attached to a template.
I'm hoping there's a solution here since there are 250ish emails I need to update...
