WordPress Dev: How to send html email using wp_mail()?

Recently got a request to configure wordpress plugin to send html email using the native wp_mail() function. The main purpose is to beautify the email layout with some colourful content. So i dig into the wordpress codex and i managed to find a filter that helps to configure the email content type from ‘text/plain’ to ‘text/html’. Meaning, i can easily configure the wp_mail() function to send html email!

To send html email using wp_mail() function, try out the code below:-

By configure the filter for ‘wp_mail_content_type’, it can direct wp_mail() function to send html email.

 add_filter( 'wp_mail_content_type', 'set_html_content_type' );

 wp_mail( 'sendto@thisemail.com', 'The subject', 'The HTML content here' );

 remove_filter( 'wp_mail_content_type', 'set_html_content_type' );

 function set_html_content_type() {
	return 'text/html';
 }
