How to Resolve HTML Rendering Issues in PHPmailer?

Understanding HTML Rendering in PHPmailer

When using PHPmailer to send HTML code, you might encounter instances where the actual HTML code is displayed in the email instead of the intended contents. This issue can be resolved by considering the following:

Correct Sequence of Method Calls

The order of your PHPmailer method calls plays a crucial role in ensuring HTML rendering. Specifically, the isHTML() method must be called after the Body property has been set.

<code class="php">$mail->Subject = $Subject;
$mail->Body = $Body;
$mail->IsHTML(true); // Call IsHTML() after $mail->Body has been set.</code>

By following this sequence, you instruct PHPmailer to treat the Body property as HTML content, ensuring proper rendering in the email client.

Additional Considerations

• Ensure that the Content-Type header is set to text/html in the email headers.
• Check that your email client supports HTML rendering.
• Review your HTML markup for any potential syntax errors that could prevent proper rendering.

By adhering to these guidelines, you can ensure that your PHPmailer emails render HTML content correctly, providing a more polished and engaging experience for your recipients.
