in reply to Updating variable in a loop

You can use something like the following to construct one large string: 
my $log = "";
for my $item (@stuff) {
  do_something($item);
  $log .= "Email sent to: $item<br>\n";
}

print $log_file $log;

The  $log .= "..." appends the string to $log each time through the loop so at the end, it's one large string.
