 Why Are My Emails Sent Using PHP's Mail Function Ending Up in Junk Mail?

Preventing Sent Emails from Landing in Junk Mail using PHP Mail Function

When emails sent using PHP's mail function end up in junk mail, it can be frustrating. Here are some potential reasons why this might occur and a solution to rectify it.

Headers Configuration

Meticulous configuration of the email headers is paramount in ensuring emails evade junk mail filters. One crucial adjustment is to employ a custom value for the "From" header. By specifying the sender's email address directly in this header, mail servers are less likely to classify the email as spam.

Example Headers

A well-configured set of headers can be found below:

$headers ="From:<$from>\n";
$headers.="MIME-Version: 1.0\n";
$headers.="Content-type: text/html; charset=iso 8859-1";

Additional Considerations

In addition to proper header configuration, other factors can contribute to emails being marked as junk:

  • Content: Avoid using excessive exclamation points, spammy phrases, and links to suspicious websites.
  • Subject Line: Keep subject lines concise, informative, and free of ALL-CAPS or excessive punctuation.
  • Sender Reputation: Establish a positive sender reputation by consistently sending legitimate emails.
  • Spam Trigger Words: Refrain from using words like "free," "money," or "discount" in the body of your emails.

Solution

By implementing the recommended changes to your code and considering the additional factors mentioned above, you can significantly reduce the likelihood of your emails being directed to junk mail folders.
