3. AWeber:

I would like to recommend AWeber email autoresponder, if you have a website with over 10,000 to 20,000 page views on daily bases. It also works well if you want to manage a huge database of customers.

Moreover dashboard ease of use is OK and not as good as i Contact or Get Response. Good for mobile or handheld devices.
