SUBJECT: EECS 280 Mid-semester Progress Report
FROM: My Self <myself@mydomain.com>

Dear {{name}},

This email contains our record of your grades EECS 280, as well as an estimated letter grade.

Project 1: {{p1}}
Project 2: {{p2}}
Project 3: {{p3}}
Midterm exam: {{midterm}}

At this time, your estimated letter grade is {{grade}}.

{% if grade == "C-" -%}
I am concerned that if the current trend in your scores continues, you will be on the border of the pass/fail line.

I have a few suggestions for the rest of the semester.  First, it is absolutely imperative that you turn in all assignments.  Attend lecture and discussion sections.  Get started early on the programming assignments and ask for help.  Finally, plan a strategy to help you prepare well for the final exam.

The good news is that we have completed about half of the course grade, so there is an opportunity to fix this problem.  The other professors and I are happy to discuss strategies together during office hours.
{% elif grade in ["D+", "D", "D-", "E", "F"] -%}
I am writing because I am concerned about your grade in EECS 280.  My concern is that if the current trend in your scores continues, you will not pass the course.

If you plan to continue in the course, I urge you to see your instructor in office hours to discuss a plan for the remainder of the semester.  Otherwise, if you plan to drop the course, please see your academic advisor.

You can add:

- Emphasis, aka italics, with *asterisks*.
- Strong emphasis, aka bold, with **asterisks**.
- Combined emphasis with **asterisks and _underscores_**.
- Unordered lists like this one.
- Ordered lists with numbers:
    1. Item 1
    2. Item 2
- Preformatted text with `backticks`.
- How about some [hyperlinks](http://bit.ly/eecs485-wn19-p6)?

Hi, {{name}},
