how can i catch the errors returned after sending the mail

Replies: 0

i am using AWS for sending mail, some mails return complain after sending, how can I get this complain?

can i use this hook?
does it work after sending?

do_action( ‘wp_mail_smtp_mailcatcher_smtp_send_after’, $is_sent, $to, $cc, $bcc, $subject, $body, $from );

or the same error I have in this hook is returned by the wp_mail () function?

what is better to hook to your hook or take the return value of the wp_mail () function?

thank you very much
