Can't find echo error

[tgavin]

I have a textarea that allows for multiple email address insertion, each address on its own line. There are two checks; address validation and duplicate checks. When each check is run on its own the info echoed is correct.
However, when both checks are triggered the 'invalid format (bad)' check echos what appears to be blank spaces left over from email addresses that passed and were inserted.

I've tried to unset(), among other things but can't figure out where the "problem" is happening. Again, when triggered by itself it echos fine.[code]<?php
if(isset($_POST['addMultiple_x'])) {

    $newemails = trim($_POST['emails']);
    
    if(!$newemails) {
        // textarea was left blank
        alert('\nIt looks like you were attempting to enter multiple test email addresses, although the text field looks empty.\n\nPlease double-check that at least one email address is entered and try again.','subs_add.php');
        exit;

        // check for duplicate email addresses
        if($_POST['check_dups'] == 1) {
            email_check($email);
