I have an email issue in WordPress woo-commerce email. it is sending an email using a header plain text email.
X-Mailer-Type:WPMailSMTP/Admin/Test
when I try to send an HTML formatted email using the below header it's not sending. However, both emails are logging in to WP Mail Logging.
Content-Type: text/html; charset=UTF-8
I had tried to disable possible security plugins and Spent hours until I found this issue. any WordPress expert developer please help.
You can try add this filter in your theme's functions.php or plug-in code
