Hi Stéphanie,
alternatively, you can try using the more classic XWiki way - I think
something like this should work :
#set($usrDoc = $xwiki.getDocument($context.user))
#set($usrObj = $usrDoc.getObject('XWiki.XWikiUsers'))
#set($emailProp = $usrObj.get('email').value)
$emailProp

  Hello,
 Happy new year to everyone.
 I'm trying to have the email of an user and I want to put it on every
 document the user creates.
 For that, I try this two differents codes :
 #set($mail=$xwiki.getUser($doc.getCreator(), false).getEmail())
 and an other try :
 #set($user=$xwiki.getUser($doc.getCreator(), false))
 #set($mail=$user.getEmail())
 But none of this two codes is right. What should I do to have the email of
 my user ?
 Best regards,
 Stéphanie
