You are hunting for work, picking up freelance gigs, or just trying a new tool, and every signup asks for an email. You type in your main address because it is quick. A week later, the follow-ups, newsletters, and 'just checking in' notes start piling up, and the important messages get buried.

Short version: pause, grab a temporary address, use it once, grab the code, and walk away. The steps below spell it out, with a side-by-side comparison, a few tips, and the limits you should know before you rely on it.
