They have given me great support with my queries from time-to -time when I was having issues while implementing their services at one of our locations, they were always there for us! The customer service provided by them has been fantastic so far as well!! Not much dislikes about it now since we started using wundersailing's mailings solution but maybe not giving more options in choosing colors etc can be improved upon? We used several mailing solutions before switching over to this platform; however nothing could beat its performance compared to others available then too. Great product overall :) It helps you get better results than ever expected! Automate boring tasks & increase efficiency without any hassle!! Mailer templates are very easy customizable which saves lotsa times spent creating custom emails every single day (if needed). There really isn't anything bad i would say here except if anyone else had some suggestions or ideas.
