Email on Bounce List

I got an alert when I logged into JotForm that usoffice@mastersacademy.org was on the bounce list, so I tried changing the email to athletics@tmaeagles.org and got the same alert....how do I say usoffice@mastersacademy.org is a safe email to use?

I have removed both emails from the bounce list. They ended up in the bounce list because your mail service provider is rejecting emails from us, probably due to suspected spam. They should both work fine now. 

For future reference, please refer to the guide below to remove emails from the bounce list:
