Small trick that helped me reduce email spam a lot

Not sure if this is common knowledge, but I recently changed how I handle signups online.
Instead of using my personal email everywhere, I started using a Temporary Email Generator[https://www.tempemail.cc/blog/temporary-email-generator] for things like:
● free trials
● downloading resources
● testing random tools
Basically anything that doesn’t need long-term access.
It takes like 2 seconds to generate an email, you still get the verification code, and then the inbox disappears later.
Biggest difference so far:
● way less spam
● cleaner main inbox
● fewer random marketing emails weeks later
I still use my real email for important stuff, but for everything else this feels like a no-brainer.
Anyone else doing this or using another method?
