What does this screenshot mean?

If I remove the email address, how can I get emails from you?

Screenshot you provided means that email address of your account is added to the bounce list and that we stop sending emails to your email address. 

There are several reasons why your email address may have been added to the bounce list. It could be due to a non-existent/inactive email address, your mail server being unavailable, your email server has rejected the emails due to suspected spam, your mailbox is full or JotForm is on your blacklist. JotForm will stop sending emails when your email address is on the bounce list. Please note that high bounce rates will put our sending method at risk so we have to process the bounce messages without exceptions.

I have checked and you email address is not in the bounce list anymore, so I assume that you have removed it from the bounce list. 

You also can follow this guide on how to check and remove the email from bounce list.

Also you should contact your email provider and ask them to Whitelist JotMails IP Addresses.
