Hi @karl_oliverio
If you run the send an email option in a do until loop
the moment you recieve the response you can check if item was already updated, if yes then send email to user about error and that his response will not be applicable or if you want you can re-run the loop again
(once the send an email with options is sent - there is no way to show error there)
