I am unable to delete message field from the simple contact form. I can select it separately, but not delete it.
You can‘t. An email without a message is no email.
If you simply want to collect email addresses, you should use a widget from a service like jotform.
You are right. It works just as described in your screenshot.
Not sure, if this was modified in one of the last versions.
Please excuse the confusion!
No problem. Just glad I could get it to work!
