Rated 5 out of 5 stars

Changing my review to five stars. Once I went back into settings and grasped the inner workings, everything is working great. Thank you for a wonderful way to personalize my email and make it easier on the eye!

Rated 4 out of 5 stars

I have tried it on two different machines with the default theme and other themes. It just does not change to the colors as I have set them.

It is just what I was looking for, wish I could get it to work.
