@jg135,
If you’ve accidentally marked an e-mail as unsafe, the e-mail message will be directed to your deleted folder. And the e-mail address will automatically blocked from entering your account. It is best that you double check your Blocked Senders list. Here is the link to learn how to do that.

I also suggest that you add the sender to your Safe List.
I’ve also edited your posted e-mail address; this is done to keep the privacy of your account.

Since you can still receive e-mails from the sender that you’ve accidentally marked as unsafe, there is no need for you to worry about. However, it is still a good advice that you check your Blocked Senders List and add the sender to your Safe List.
