The best thing about this software it's easy to use, you can easily set up auto-responders or even build custom campaigns in minutes! That’s why I always recommend using them for any marketing campaign that requires multiple emails like newsletters etc.. There isn't much i dislike at all but they could do with more customer support as well so many customers are unaware of its features which makes us feel bad when we try explaining our requirements without knowing how complicated their system actually was/is :). It helps me send out my newsletter updates very quickly than traditional methods (i'm talking hours vs few mins) plus there were times where some people couldn´t find certain items within an email list because axionx made things easier by adding those filters automatically - saving time too :) Highly recommended if your looking into sending automatic messages through one single tool then go ahead otherwise spend extra money elsewhere since other tools have.
