Use custom shortcodes in email

Hi,
I’m trying to use custom shortcodes (not the ones included by cf7) in the email template. Does anyone have an idea how to do this?

I tried:
`function shortcodes_in_cf7( $form ) {
$form = do_shortcode( $form );
return $form;
}
add_filter( ‘wpcf7_form_elements’, ‘shortcodes_in_cf7’ );`
But that didn’t work out at all.

Further I tried creating my own shortcode specially for cf7 like this:

wpcf7_add_shortcode('custom_shortcode_1', 'wpcf7_custom_shortcode_1_handler', true);

function wpcf7_custom_shortcode_1_handler($tag) {
    if (!is_array($tag)) return '';

    $name = $tag['name'];
    if (empty($name)) return '';

    $my_shortcode = "some custom content to be displayed by the shortcode";
    $html = '<input type="hidden" name="' . $name . '" value="' . $my_shortcode . '" />';
    return $html;
}

and then calling this using [custom_shortcode_1 my_shortcode] in the form and [my_shortcode] in the email, but I don’t like the fact that my shortcode content is loaded in my form, for everyone to be seen.

Does anyone have a clue how to do this?

Thanks a lot!
