I like that it's easy to use and is completely free, which makes this an attractive option for many users. The service also offers excellent customer support! It can be difficult at times to find what you're looking for in terms of account settings or features. You need to know how to navigate the site well enough to get around without assistance from the live chat feature. This is a great software solution if you want something simple but effective. We were able to send mass emails with ease using this program.
