How are email notifications handled when the account email no longer exists?

We manage a JotForm account for a client that was recently acquired by another company. Like with most acquisitions, the email domain that was being used prior was retired. However, they did not realize that their JotForm account was still tied to their old email domain handle at the time it was deactivated. I expected that once I updated the account email that there would be a back-log of submissions that hard bounced due to the email no longer working, and that those submissions would attempt to be re-delivered once the new email address was entered. However that did not happen. Is there some kind of email notification error log that might help me pin-point exactly which forms did not go through?

For more context, this is a job application and the email notifications for the forms I am inquiring about were being sent to both the applicant's email AND the account email. Just saying this in case it matters that one email was going through to the applicant, but the email going to the account email hard bounced.

Thanks in advance for any help on this. I will include the link to the form below but not sure it will help in this situation.

Hello,

Thank you for your message.

In this case, at the moment we don't have a bounce email log since the emails will be redirected to the Recipient Emails email.

Under the account history, you can see all the emails that have been sent fro your account: https://support.jotform.com/myaccount/history, so you can take a look at all the emails that were sent from the company acquisitions.

If you need any further assistance, please let us know. We will be happy to help.
