Make sure you are using the right email address. Some email formats could include an underscore. Underscores (_) can look like spaces. As an example, firstname.lastname@example.org might look like john email@example.com.
Wait a few minutes and try sending your message again. Temporary mail server issues can sometimes cause email delivery problems.
