Is there an action_hook or something similar that could help me achieve this?

I tried adding markup in a PHP string variable and just fired off an email with the wp_mail() function like so:

$email_to = 'someaddress@gmail.com';
$email_subject = 'Email subject';
$email_body = "<html><body><h1>Hello World!</h1></body></html>";
$send_mail = wp_mail($email_to, $email_subject, $email_body);

But it showed up as plain text?

Any ideas?

from wp_mail codex page:

The default content type is 'text/plain' which does not allow using HTML. However, you can set the content type of the email by using the 'wp_mail_content_type' filter.

// In theme's functions.php or plug-in code:

function wpse27856_set_content_type(){
    return "text/html";
}
add_filter( 'wp_mail_content_type','wpse27856_set_content_type' );

    Hmm sounds useful. Just a question, any particular reason why you named your function wpse27856_set_content_type?

    No, it's just a unique name based on the id of this particular question. wpse = wp stachexchange, 27856 is the id of this question in the URL. I just do that to avoid potential collisions if people copy/paste code out of here.

    You can also just include the Content-Type in your email headers. Check out how the Notifly plugin does it.

    This will break your password reset email, because the reset link is wrapped in <>. Oct 24 '17 at 6:08

    @SimonJosefKok, if I'm reading this bug report correctly, the issue of breaking password reset emails is resolved as of WordPress 5.4. Sounds like they decided to remove the angle brackets from the email address. core.trac.wordpress.org/ticket/23578#comment:24

As an alternative, you can specify the Content-Type HTTP header in the $headers parameter:

$to = 'sendto@example.com';
$subject = 'The subject';
$body = 'The email body content';
$headers = array('Content-Type: text/html; charset=UTF-8');

wp_mail( $to, $subject, $body, $headers );

    This works better as the add_filter sometimes shows as attachment. Thanks for sharing!

    This is the generally best way to-do this. The top answer will interfere with other plugins and cause problems. Dec 6 '19 at 19:12

Don't forget to remove the content type filter after you use the wp_mail function. Following the accepted answer naming you should do this after wp_mail is executed:

remove_filter( 'wp_mail_content_type','wpse27856_set_content_type' );

Use ob_start, because this will allow you to use WP variables/functions like bloginfo etc.

make a PHP file and paste your HTML in that file(use wp variables inside that php file if needed).

Use the below code:

 $to = 'Email Address';
 $subject = 'Your Subject';

 ob_start();
 include(get_stylesheet_directory() . '/email-template.php');//Template File Path
 $body = ob_get_contents();
 ob_end_clean();

 $headers = array('Content-Type: text/html; charset=UTF-8','From: Test <test@test.com>');
 wp_mail( $to, $subject, $body, $headers );

this will keep your code clean and due to ob_start we will also save the time of loading the file.

Another easy way I'm going to share below. Even you can style your mail body as your wish. Maybe it's helpful for you.

$email_to = 'someaddress@gmail.com';
$email_subject = 'Email subject';

// <<<EOD it is PHP heredoc syntax
$email_body = <<<EOD
This is your new <b style="color: red; font-style: italic;">password</b> : {$password}
EOD;

$headers = ['Content-Type: text/html; charset=UTF-8'];

$send_mail = wp_mail( $email_to, $email_subject, $email_body, $headers );
