Thanks for the correction Dave. Also, you should take a look at here-strings if you are going to be compiling a message to the user for ease of formatting:
$managername = Get-ADUser jsmith | Select name $body = @" Dearest $($managername.name), Some message blah blah blah Your technically apt IT God, Frank "@ $body
Only catch is here-strings are picky with indentation and line breaks, but it's much easy to format and read large amounts of text.
