Sometimes I don’t want to open eM client and compose a new mail, but want to just compose a new mail without opening the application. Thunderbird has a task like that, just by right clicking on the program icon and starting a new mail. the problem comes into sight when i want to compose and email by clicking on an email address in my web browser, eM as the default application handles it but after sending the message eM client remain opened!
Is there any to handle it? 
Hello,
I am sorry, but it is not currently possible.
He didn’t even try to pretend like they’re going to implement this. How sad!
I added it to our feature request list so you can expect it in one of our future updates.
