Conditional display of empty fields in custom email notifications

In the default email notification (without custom HTML or plain-text formatting), fields that are not filled in by the user are automatically omitted from the email output, which results in a clear notification. However, when a custom email template is used (HTML or plain text), all fields are rendered regardless of whether they contain a value, resulting in multiple empty or blank entries in the email. This significantly reduces readability, specially when the form has more than 30 fields. It would be extremely useful to have a built-in mechanism—such as conditional logic or an automatic “hide empty fields” option—that allows empty form fields to be excluded from custom email notifications, replicating the behavior of the default system-generated email. This enhancement would improve usability and make advanced email formatting more practical for complex forms with many optional fields.
