Hello, I restart this post because I also have a problem with this feature.

I have a form including the shortcode [text], [email], [tel], [number] and [textarea]. I wish that when sending the form all the fields that have not been filled do not appear in the mail.

I checked the box “Exclude lines with blank mail-tags from output”.

The empty fields [email], [tel] and [number] are not displayed, but the other empty fields [text] and [textarea] are always present in the body of the email.

Have you ever encountered this problem ? Do you have a solution to avoid this ?

Here is an example of a field that appears in the mail :
<label>[text contenance-3 class:requiredField placeholder "Contenance en ml"]</label>

Thanks in advance.
