Planet-SaveEcologyFund
Care2
EcologyFund uses some intrusive advertising like pop-ups and therefore I recommend using the other two instead. In addition to using less introsive advertising the ads you see on Planet-Save and Care2 are always related to ecological products and services. Many of these are actually quite interesting if you are into that sort of thing. Because of the excessive pop-up advertising I don't consider EcologyFund to really qualify as an Easy Donation. Planet-Save on the other hand is excellent and even better than the industry standard Hotmail.
The biggest advantage of using Planet-Save or Care2 instead of Hotmail is the amount of junkmail you are going to get. Even if you never tell anyone about your Hotmail account, you will soon start receiving junkmail and lots of it. With Planet-Save you will be getting significantly less junkmail if at all.
In addition to receiving less junkmail there are other benefits as well. For example you don't need to login every 30 days to keep your Planet-Save account active (like you do with Hotmail). For a simple comparison see the chart below. The chart refers to the free email service offered by each and Hotmail is included only as a comparison (using Hotmail does NOT create donations).
