Why it matters
How disposable email protects you
Your real email address is a permanent identifier that ties your accounts together and shows up in breach dumps years later. A disposable email breaks that chain. Spam lands in an inbox you can burn the moment you are done; tracking pixels never fire because remote images are blocked by default; and if the site you signed up with is hacked, the address in the dump leads nowhere once you have burned it. You get what you came for without adding yourself to anyone’s database.
