Increased built-in email list functionality and allowed us to stay in closer contact with potential clients
Seamlessly integrates with Magento and other shopping carts to extend your email functionality and improve customer relations on a ongoing basis.
I would just suggest a larger template library and possibly simplify the mail merge features to allow for easier access to mail merge customization.
Easy to install
Easy to use
Space is good enough
Layout is sleek
Doesn't everything you expect from it
Sometimes it takes time to fetch emails with attachments
Can be a bit costly when u run out of space
