title: TYPO3 Powermail confirmation to logged in frontend user email
body: <p>In Powermail it is possible to send a confirmation e-mail to a filled in e-mail address. When a frontend user is logged in this field can be prefilled with that user's e-mail address. However we don't want to show the field with the e-mail address. If we change the field to a hidden field it is no longer possible to set the field as the sender e-mail address.</p>
  
  <p>So the question is, is it possible to send a confirmation e-mail in powermail to the logged in frontend user's e-mail address without showing that e-mail address in the form?</p>
  
  <p>For this site we use TYPO3 7.6 and Powermail 4.4.0.</p>
