When you use a temporary email, it's not forever—most services set a time limit, usually between 10 minutes and a few hours. After that, the inbox disappears, wiping all messages. This helps protect your real address from spam and clutter, but it also means you have to grab what you need fast, like a confirmation link or a one-time code. It's a handy tool for quick sign-ups and avoiding unwanted emails.
