I did include "gmail.com" in the filters, but it still doesn't leave out stuff from Gmail.
Here are the filter instructions:
Filters allow you to disable tracking on websites. Enter filters into the box below (one per line). For example, if you don't want your comments on Facebook tracked enter "facebook.com" (without the quotes).
I'll try including
mail.google.com in the filter as well. But are there any other alternative filter suggestions?
