in reply to Updating variable in a loop

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

    So I would use another loop within my loop? Here's what I'm doing: 
    $SQL = "Select * from database where (TO_DAYS(enddate) - TO_DAYS(Now()
+) = 8) AND payment!='premium'";
&Do_SQL;
$recordcount = $sth->rows;
if ($recordcount > 0) { 
    $sendEmails = 'yes';
    }
    
if ($sendEmails eq 'yes') {
    $count = 0;
    while ($pointer = $sth->fetchrow_hashref) {
        $contact = $pointer->{'contact'};
        $toemail = $pointer->{'email'};


    open (MAILPROG.....";
    SEND THE EMAIL HERE....
    close (MAIL);
    
    print "email sent to: $contact <$toemail>\n";
    $count++
}
    print "Sent $count emails.\n";
    
    $action = "Email Reminders sent!";
    $log = "Sent $count emails.";
    &log_it;

    I'd like $log to also have every email address that received an email. It would look something like this in the log: 
    Sent 4 emails.<br>
Email sent to user1<br>
Email sent to user2<br>
Email sent to user3<br>
Email sent to user4<br>

    I need to get the $log variable within my existing loop but have it updated with every email. So do I have to run a separate loop within my loop?
