I love that you can send bulk email addresses (i've used them for about 2 years) as well have your own domain! There is nothing i dislike right now but maybe if they were adding features faster then this would be something else...but not really sure what? We use earth class mailing services through our work at my organization so we're able find people's info easily when needed or sending out mass emails such using up time tickets etc.. I love that you can create folders for your bills. It's very simple and easy to use. There is nothing about this product that I dislike. This is a great way to organize your bills. You can also have other people in your household sign up for it so they can also see what bills are coming in. We use it for our mortgage payments and insurance payments. This allows us to keep track of everything we need to pay.
