Hi Felipe!
I work at Pressable. Many managed WordPress hosts, including Pressable, have built-in high-performance caching. The bottom line is, you don’t need WP Super Cache as long as your host includes caching. In your case, the built-in caching does more than a caching plugin would.
Plugins like WP Super Cache are important for self-hosted or non-managed WordPress sites (on hosts like Digital Ocean). Your Pressable sites also have other performance features, including MaxCDN and load balancing, built in. You can learn more about Pressable’s performance features on this article: https://kb.pressable.com/article/how-pressable-powers-your-website/
