Cant send to an ID – Threema. The Secure Messenger Review

I didnt put in my email or any other self identifying information. Im trying to send to someone elses ID who did the same. It appears you cannot do this. Am I wrong? If not please fix this. My situation is even more secure without self identifying information. Without this scenario I dont see that this app is necessarily more secure than other apps. As part of my profession I do computer security as well
