Disclaimer: I haven’t tried paid apps which teach you inbox zero like Superhuman etc. Also I routinely fail at this and have now given up.
Jeff Su has couple of videos around Inbox Zero. Do check them.
here.
Inbox Zero makes sense for you if you are able to accept that reaching that state doesn’t mean you have done all the things you wanted to do with your email. There will be emails you want to action out later, newsletter you plan to read only if you get time, newsletter/emails you must read at a certain time etc. Many people including me struggle with this concept as we feel done means done.
You need to have rituals, process for these future tasks, optional items etc. Otherwise you will never move things outside your email home view and always feel like a lost cause.
Many other people also struggle to prioritize or accept that certain things are just not important or worth to be on top of. If you cannot do that, you will never get there. You would have moved things from one folder to another folder.
My suggestion is to attempt this, iterate to fit your style/needs and most importantly accept the principles/ideas behind Inbox Zero. Expect failure and plan around it
