Why Are My PHP mail() Emails Ending Up in Spam, and How Can I Fix It?

Preventing PHP Mail() Emails from Spam Classification

Issue: Emails sent using PHP's mail() function are consistently landing in spam folders, despite various attempts to resolve the issue.

Solution:

To ensure that emails sent through PHP's mail() function avoid spam classification, it is crucial to add necessary needle headers to the email. These headers include:

From: [email protected]
Reply-To: [email protected]
Return-Path: [email protected]
CC: [email protected]
BCC: [email protected]

Implementation:

$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!";
}
?>

By incorporating these headers, you can increase the likelihood of your emails being delivered successfully and avoiding spam filters.
