It will NOT work. I can't think Why?

Because the MIME-encoded parts are not properly terminated. GIGO. They should end with ?=. By changing them to ensure that they are properly terminated they work fine.

#!/usr/bin/env perl 
use strict;
use warnings;
use Encode qw(encode decode);

my @subject = ("Room Rush \303\242\302\200\302\223 Enjoy 25% off on yo
+ur stay. (raw: Room Rush =?utf-8?b?4oCT?= Enjoy 25% off on your stay.

"Last Day To Enjoy Extra 15% OFF On Everything For NDB Credit Cards (r

    my $decoded = decode ("MIME-Header", $subj);
    print encode ("UTF-8", $decoded) . "\n";
