I am trying to increase the $count variable by 1 whenever any line in the opened file contains the word Mailto:

However, I kept receiving use of uninitialised value $count error and a long string of numbers at the end as the result.

my @email = <OPENFILE>;
close OPENFILE;

my $count;

foreach my $email (@email){

    if ($email =~ /mailto:/) {
    $count += 1;

    }

    print $count; # error here
}
