Formatting cron email

Trying to format the cron email to no avail. I get the emails, but cannot format them. They are Content-Type: text/plain; charset=UTF-8 but I cannot get the output to format in single line with a cartriage return. For instance I want the output to be "User $fname $lname ($id) sent dues reminder "User $fname $lname ($id) sent dues reminder "User $fname $lname ($id) sent dues reminder I have tried \n, \r\n,
, . PHP_EOL and every combination you can think of. \n\n does give me double spacing but \n does nothing. Any solution to this? Thanx
