Hello I don't recieve the submissions in my mailbox anymore

I have checked the email address set as the recipient of your email notifications and found out that it is on the bounce list.

I have successfully removed it from the list and everything should work as before, however, so you could prevent this from happening again in the future, I suggest you check this guide, How-to-setup-email-alerts-to-prevent-email-bouncing-related-issues

Or, you can also try Whitelisting-JotMails-IP-Addresses

Please let us know if you need any further assistance. Thank you.
