It's easy to create folders in the iOS Mail app, and if they're used, they're incredibly helpful at keeping related emails grouped together. However, if you no longer use a folder, it's completely safe and easy to delete it.

Deleting folders in the email app on your iPhone or iPad instantly removes all of the messages in the folder as well as the folder itself. It's one of the easiest ways to regain storage on your phone and to declutter your emails.
