Question: For example, when we use Espresso with a listview, we're supposed to populate it prior to using it right? I couldn't figured it out how to do that properly. 

I mean is it possible via Espresso itself or do I need to set it up in a method with a @Before annotation.

Thanks

Answer: 
If you're ok with an external Email Service then look for one that offers a Web Service API (which I assume your firewall is ok with).

SendGrid for example: <https://sendgrid.com/docs/API_Reference/Web_API/mail.html>
Use Database Mail.
[Click here](http://blog.sqlauthority.com/2008/08/23/sql-server-2008-configure-database-mail-send-email-from-sql-database/).

Pass your mail list from c# to Database.From there write a procedure to send mail.
We can easily monitor sent mails.
