I have a proposal solicitation application where I select typically 5 or so individuals and they get individual emails such as "Hello Bob, please click <here> if you wish to provide pricing for the following scope of work..."  It uses PHPmailer with a smtp gmail account.  The FROM name is my name, the FROM email is an email account associated with the application <bidding@bidsoliciationapp.com>, and the REPLY-TO name and email are both mine. 

A while back, individuals have told me that my emails often windup in their spam folder.

What might be causing this and what can be done to decrease its likelihood?

One potential culprit is all of the emails have a small footer with a disclaimer and a link back to a website, but the link utilized https which was no longer supported on the site and was broken.  Maybe related?

Thanks

I've followed every piece of advice (quotes, no quotes, $...) and nothing works. Here is the snippet of code that's generating the error. This woks fine in PHP 5, but I have to upgrade to 7. Warning if for line 71, which corresponds to where query3 starts. 

if($numRows == 0) {
        $query3 = "INSERT INTO comments (article_id, status, date_posted, feedback, visName, visEmail, notify) VALUES ('".$_POST[article_id]."', '0', NOW(), '$visFdbk', '$nameOfVis', '$emailOfVis', 'y');";    
    }else{
        $query4 = "INSERT INTO comments (article_id, status, date_posted, feedback, visName, visEmail, notify) VALUES ('".$_POST[article_id]."', '0', NOW(), '$visFdbk', '$nameOfVis', '$emailOfVis', '');";
    }
    
}
 

Earlier in code, I define this: $numRows = mysql_num_rows($r);

Thanks in advance for any help you can lend.
