Mail goes to spam if attachments are disabled

I've set up a regular form with 5 attachments. It's all working fine as expected. Now, I don't want to send the uploaded files as attachments since they can be quite big. So, i've put in the following code before submit

<h2>Thank You for the support request</h2>
<p>We will get in touch with you soon</p>
<?php
$i = 1;
$op = 'Following files were uploaded <br /><br />';

foreach($attachments as $attachment) {
$link = JURI::root() . 'components/com_chronocontact/upload/' . basename($attachment);
$op .= 'File #'.$i.' <a href="'.$link.'">'.basename($attachment).'</a><br/>';

}
$html_message = str_replace('{files_list}', $op, $html_message);
$attachments = null;
?>

When I put this code, the mail comes in as expected, it has the list of files, and no attachments, exactly as expected. But only, in this case, the mail is delivered to my spam folder. Instead of the above, if i put in just

<?php
$attachments = null;
?>

The mail comes to my inbox

Just reinforcing the fact that this is NOT a Chronoform bug, just Gmail marking it spam. I'm posting it here just to see if someone else has had a similar problem and were able to solve it! Seems like gmail is marking it spam since it thinks its a phishing mail because it has some links.

Thanks in advance,
Ashwin

Hi Ashwin,

What I know is that they may not be marked as spam but after a while, I think its using neural thing and learns that. 😑
