All contacts being sent to spam

Having a problem that all messages sent via the contact form are being sent to spam.

Have tried adding

add_filter( ‘wpcf7_recaptcha_verify_response’,
function( $is_human, $response_body ) {
$score = isset( $response_body[‘score’] ) ? $response_body[‘score’] : 0;
$threshold = 0.3;
$is_human = $threshold < $score;
return $is_human;
},
10, 2
);

to the function.php but even with the threshold set to 0 messages are still sent to spam.

What am I doing wrong?
