What e-mail name conventions are used
This is a small overview of what e-mail name patterns I have encountered and which I find preferable. Let us assume that my name is Thomas Kuhn and my postal address is structure.com.
The most prevalent pattern or convention is email@example.com, this is my favorite. Other patters are firstname.lastname@example.org and ThomasKuhn@structure.com. Also, note that Thomas.Kuhn@structure.com is not really different from the first one, because capital letters do not matter in e-mail names.
Another option would be email@example.com.
