How can I format email notification after registration?

Question

I saw already this answer. And it helped me to make unique mail. It's great. But how to format some text using HTML? For example to work with tags

 <b> <i> <font color="red"> <img src="">

I wrote

spintf("<a href="http://site.com/some-page">Text</a>");

And on my mail I got letter with <a href="http://site.com/some-page">Text</a> instead of this Text. It seems that WordPress mailer cut HTML, cause I tried printf and echo. Or may be I just do something wrong?

wp_mail from Codex

Use this example:

add_filter( 'wp_mail_content_type', 'set_html_content_type' );

wp_mail( $mails_to, 'The subject', '<p>The <em>HTML</em> message</p>' );

// Reset content-type to avoid conflicts -- http://core.trac.wordpress.org/ticket/23578
remove_filter( 'wp_mail_content_type', 'set_html_content_type' );

function set_html_content_type() {

    return 'text/html';
}
