Add Plain-Text Email

Add Plain-Text Email This plugin will add a plain/text version of your HTML emails to your WordPress emails. This decreases the chance of your legit emails being marked as spam by tools as SpamAssassin. This plugin comes without any settings. When activated, it will automatically look for HTML emails being sent using the wp_mail() function and when necessary add the plain text version. The source code of this plugin is available on GitHub: ibericode/wp-add-plaintext-email. About the plugin author Danny van Kooten has been building WordPress plugins since 2010, starting with WordPress 3.0. He is the founder of ibericode, the small software company behind popular WordPress plugins including Mailchimp for WordPress and Koko Analytics.
