I like that it's easy to use, has many features for various email campaigns/emails we send out in our business; It is also very quick when sending large numbers of emails (even if you have an older computer). We've been able fix some problems such as having too much junk mail from customers who think they are receiving free products or services - which was not good! The fact there were so few issues with this software made us believe more highly than other programs would be great feedback about their customer service-ability / ability etc., but all seemed fine though no real complaints here either way.- Great product &.
