I liked how easy it was for me as someone that's brand new at this e-mail stuff! No fancy tutorials or anything else other than just jumping right into sending emails out through my favorite web browsers like Gmail & HotMail/Outlook etc.. The setup process seemed rather short but also simple enough so any person could understand what your doing without having some sorta "expert" do everything instead you yourself can learn all about setting email servers by using your own self taught efforts!! Nothing really specific dislike besides maybe getting confused sometimes when trying different things during setttings? Like if one thing doesn't work then look online again because there are plenty people who might have been able guideyou step further along through those troubleshooting steps before asking here :) But nothing majorly dislikes either haha. All great info shared within help pages which make sense too since they give tips throughout their explanations making sure we're not missing important information. Emailsuccess has been very reliable for our domain. It's easy to set up and configure. The support team is always willing to help you out when you need it. I would like to see some more options for the templates that are available. If you're looking for a robust MTA product, this is the one to go with. We use Emailsuccess to send bulk emails through the web interface and we have not had any issues with it in over 2 years.
