Why does my mail go to spam?

The first and most obvious reason for your emails ending up in spam is because your recipients put them there. Even if your content is strong and the recipient expressly gave you permission to contact them, they may still decide to mark your email as spam as a way to clean up a cluttered inbox.

How do I stop spam emails in CodeIgniter?

If you notice that the emails are sent to the spam folder, use Encrypt Class in CodeIgniter to solve this issue in Gmail. You need to load the CodeIgniter Encrypt library before sending the email. It will encrypt your email and help to avoid the spamming issue in Gmail.


You must to add a needle headers:

Sample code :

$headers = "From: [email protected]\r\n";
$headers .= "Reply-To: [email protected]\r\n";
$headers .= "Return-Path: [email protected]\r\n";
$headers .= "CC: [email protected]\r\n";
$headers .= "BCC: [email protected]\r\n";

if ( mail($to,$subject,$message,$headers) ) {
   echo "The email has been sent!";
   } else {
   echo "The email has failed!";
   }
?> 

There is no sure shot trick. You need to explore the reasons why your mails are classified as spam. SpamAssassin hase a page describing Some Tips for Legitimate Senders to Avoid False Positives. See also Coding Horror: So You'd Like to Send Some Email (Through Code)


<?php

$subject = "this is a subject";
$message = "testing a message";




  $headers .= "Reply-To: The Sender <[email protected]>\r\n"; 
  $headers .= "Return-Path: The Sender <[email protected]>\r\n"; 
  $headers .= "From: The Sender <[email protected]>\r\n";  
  $headers .= "Organization: Sender Organization\r\n";
  $headers .= "MIME-Version: 1.0\r\n";
  $headers .= "Content-type: text/plain; charset=iso-8859-1\r\n";
  $headers .= "X-Priority: 3\r\n";
  $headers .= "X-Mailer: PHP". phpversion() ."\r\n" ;



mail("[email protected]", $subject, $message, $headers);

$fromMail = 'set your from mail';
$boundary = str_replace(" ", "", date('l jS \of F Y h i s A'));
$subjectMail = "New design submitted by " . $userDisplayName;


$contentHtml = '<div>Dear Admin<br /><br />The following design is submitted by '. $userName .'.<br /><br /><a href="'.$sdLink.'"><b>Click here</b></a> to check the design.</div>';
$contentHtml .= '<div><a href="'.$imageUrl.'"><img src="'.$imageUrl.'" width="250" height="95" border="0" alt="my picture"></a></div>';
$contentHtml .= '<div>Name : '.$name.'<br />Description : '. $description .'</div>';

$headersMail = '';
$headersMail .= 'From: ' . $fromMail . "\r\n" . 'Reply-To: ' . $fromMail . "\r\n";
$headersMail .= 'Return-Path: ' . $fromMail . "\r\n";
$headersMail .= 'MIME-Version: 1.0' . "\r\n";
$headersMail .= "Content-Type: multipart/alternative; boundary = \"" . $boundary . "\"\r\n\r\n";
$headersMail .= '--' . $boundary . "\r\n";
$headersMail .= 'Content-Type: text/html; charset=ISO-8859-1' . "\r\n";
$headersMail .= 'Content-Transfer-Encoding: base64' . "\r\n\r\n";
$headersMail .= rtrim(chunk_split(base64_encode($contentHtml)));

try {
    if (mail($toMail, $subjectMail, "", $headersMail)) {
        $status = 'success';
        $msg = 'Mail sent successfully.';
    } else {
        $status = 'failed';
        $msg = 'Unable to send mail.';
    }
} catch(Exception $e) {
    $msg = $e->getMessage();
}

This works fine for me.It includes mail with image and a link and works for all sorts of mail ids. The clue is to use all the header perfectly.

If you are testing it from localhost, then set the below before checking:

How to set mail send from localhost xampp:

  1. comment everything in D:/xampp/sendmail/sendmail.ini and mention the below under

    [sendmail]

    smtp_server=smtp.gmail.com smtp_port=587 error_logfile=error.log debug_logfile=debug.log [email protected] auth_password=your-mail-password [email protected]

  2. In D:/xampp/php/php.ini a. Under

    [mail function]

    SMTP = smtp.gmail.com smtp_port = 587

b. set sendmail_from = [email protected] c. uncomment sendmail_path = "\"D:\xamp\sendmail\sendmail.exe\" -t" Hence it should be look like below

sendmail_path = "\"D:\xamp\sendmail\sendmail.exe\" -t"

d. comment sendmail_path="D:\xamp\mailtodisk\mailtodisk.exe" Hence it should be look like below

;sendmail_path="D:\xamp\mailtodisk\mailtodisk.exe"
