The best thing about upcloud is that it has a very good support team who are always available to answer our questions at any time of day or night! I have not found anything bad yet but i would like if there was more control over my resources. It's really easy for someone without much knowledge to use this tool. As long as you know how to navigate through their dashboard everything will be fine. If you need help just ask them and they'll try to solve your problem right away. I am solving problems related to email marketing campaigns using upcloud which allows me to track all clicks and opens from different sources so far no issues here either.
