I have been using Mailzak's service for quite some time now and I am impressed by the rich set of features it has. I can send mails to multiple customers and track which ones got opened free of cost. Their customer support is also decent and I asked them to implement some new features and they said they will do it.
What do you dislike?
Nothing as such as of now. I will update once I find anything.
What business problems are you solving with the product? What benefits have you realized?
I run an online portal http://urbanclans.com which organises gaming tournament and for that I need to send bulk mail to customers.
