Sanitize php mail yahoo

A common issue!

When sending emails from a PHP script to Yahoo Mail, you may encounter issues with the email being flagged as spam or not being delivered at all. This is because Yahoo's spam filters are quite aggressive and may flag emails that don't meet certain criteria.

To help sanitize your PHP mail script and increase the chances of your emails being delivered to Yahoo Mail, follow these steps:

  1. Use a valid From email address: Make sure the From email address is valid and belongs to your domain. This will help Yahoo's spam filters trust your email more.
  2. Use a proper Subject: Keep your subject line concise and relevant to the content of the email. Avoid using all caps, excessive punctuation, or spammy keywords.
  3. Use a valid Reply-To email address: If you're sending an email from a PHP script, make sure the Reply-To email address is valid and belongs to your domain.
  4. Use a proper Content-Type: Set the Content-Type header to text/plain or text/html depending on the type of email you're sending. Avoid using multipart/alternative as it can trigger spam filters.
  5. Avoid using spammy keywords: Refrain from using keywords like "FREE", "WIN", "MAKE MONEY", or other spammy phrases in your email content.
  6. Use a valid MIME-Version: Set the MIME-Version header to 1.0 or 1.1 to indicate that your email is a valid MIME message.
  7. Avoid using too many links: Yahoo's spam filters may flag emails with too many links. Limit the number of links you include in your email.
  8. Use a valid Date header: Set the Date header to the current date and time to indicate when the email was sent.
  9. Avoid using too many attachments: Yahoo's spam filters may flag emails with too many attachments. Limit the number of attachments you include in your email.
  10. Use a reputable email service: Consider using a reputable email service like Sendgrid, Mailgun, or Amazon SES to send your emails. These services have better deliverability rates and can help you avoid spam filters.

Here's an example of a sanitized PHP mail script:

<?php

// Set the email headers
$headers = array(
    'From' => '[email protected]',
    'Reply-To' => '[email protected]',
    'Subject' => 'Your Email Subject',
    'Content-Type' => 'text/plain; charset=UTF-8',
    'MIME-Version' => '1.0',
    'Date' => date('r'),
);

// Set the email body
$body = 'Your email body here';

// Send the email
mail('[email protected]', 'Your Email Subject', $body, $headers);

?>

Remember to replace [email protected] with your actual email address and [email protected] with the recipient's email address.

By following these steps and using a sanitized PHP mail script, you should be able to increase the chances of your emails being delivered to Yahoo Mail.
