-As part of my work, I get to share news about travel-funding decisions for our Fedora contributor conference, [Flock][8]. A simple email tells people they've been selected for travel funding and their specific funding details. One user-specific detail is how much money we can allocate for their airfare. Here is an abbreviated version of my template file (I've snipped out a lot of the text for brevity):

-This works just like an **if** in most programming languages. Jinja2 is very expressive and can do multi-level conditions. Experiment with making your life easier by including database elements that control the contents of the email. Using whitespace is important for email readability.

 ### Mailmerge的优点
 
 Mailmerge是用来批量发送个性化邮件的简洁而高效的工具。每个人只接受到他需要的信息，其它额外的操作和细节都是透明的。
