Unable to delete email without recipient from the emailed list

One report was clicked for email without entering any recipient address. Now it is appearing in the list of email sent. When I opened the message using view option, I am getting an error message (screen shot given) without delete option.

Please help me on this.

So don’t open the message?

Give up is an easy step. I want a solution.

Forum is not the place to report bugs. You need to email it to bugs@manager.io as per the error message.
