If I understand you correctly, here's an untested example that should provide guidance:

my $count = 0;
my @sent;

while (get_entry_from_db()){
    if (/match/){
        ...; # send email and do other stuff
        $count++;
        push @sent, [$contact, $email];
    }
}

print "users mailed: $count\n";

for my $entry (@sent){
    my ($contact, $email) = @$entry;
    print "email sent to: $contact <$email><br>";
}

I've used an array of arrays here, instead of just appending the full string to the array, but you can go that route as well.

update: changed default var to named in for() loop for clarity
