 * Hi!
    Since the last update, the code is changed while sending a newsletter. There
   is always the text “3D” within the code. Here a example snippet (outlook-e-mail
   source):
 * <table style=3D”border-collapse: collapse; width: 100%;” class=3D”t=npc-row ui-
   sortable-handle” data-id=3D”content-05-imageblock” width=3D”100%=” cellspacing
   =3D”0″ cellpadding=3D”0″ border=3D”0″ align=3D”center”>
    <tbody><tr> <td style
   =3D”padding: 0;” align=3D”center”>
 * The source looks fine in the editor. But it gets broken somewhere in the sending
   process.
    Please help. Thanks a lot!
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fsending-changes-html-source-3d%2F%3Foutput_format%3Dmd&locale=en_US)

 * Maybe this is a problem with
    Content-Transfer-Encoding: quoted-printable in 
   the header. Where does thenewsletterplugin add this code to the header – and 
   why?

 * Hi, the “quoted printable” is ONE of the possible standard email encodings. The
   problem you’re facing is in your email client not being able to decode the quoted
   printable OR something in the middle changing the encoding declaration inside
   the email.
 * You can change the default encoding on Newsletter main settings to check if a
   different encoding solves your issue. For example, try “base 64”.
