I do provide our staff with a weekly newsletter on tech tips, library reads and lessons, a mix or more of one depending on the situation.  I use Smore to do this because I love the aesthetic design.  I did pay out of pocket for it but find it to be worth it as it offers a variety of choices and the creation is super simple.

The LMS at our other high school also does a newsletter and just posts it right in her email, which also works well.

Here is an example below...

Have a great day!
