This would be most likely against the way email is working nowadays, but could every email I create be sent from dynamically created alias so I do not own a real, static email address as such and I am not prone to any spam, phishing attemps and so on?

I could imagine me, my digital identity, my emails being of a digital pod which could be contacted only when I would have made a first, initial attempt.

I am not even sure if this technically makes sense,
