Same problem here. Deleted the old plugin, created a new form, but email field doesn't show
<p>[text* text-389 placeholder "nome"] </p>
<p>[text* text-374 placeholder "cognome"]<p>
<p>[email* email-505 placeholder "e-mail"] </p>
<p>[select menu-63 "Vorrei informazioni sul corso..." "HACCP" "CQC (C-E)" "CQC (D-E)"] </p>
<p>[textarea textarea-519 placeholder "messaggio"] </p>
<p>[submit "invia"]</p>
