How to use this hook

See “How to use actions and filters to customize Jetpack”.

Notes

This snippet adds autocomplete=”email” to the email input field, enabling autofill support from browsers and password managers:

add_filter( 'grunion_contact_form_field_html', function( $rendered_field, $field_label, $id ) {
    if ( $field_label === 'Email' ) {
        $rendered_field = preg_replace(
            '/<input/',
            '<input autocomplete="email"',
            $rendered_field,
            1
        );
    }
    return $rendered_field;
}, 10, 3 );

This pattern can be extended to other fields by modifying the $field_label check or changing the inserted attributes.
