Use a Throwaway Email for One-Time Signups

Sometimes you need an email address for exactly one interaction — downloading a free PDF, accessing a one-time tool, or reading a paywalled article. Using your real email for these means spam forever from a service you will never use again.

Throwaway email services give you a temporary address that works for minutes or hours and then disappears. No signup needed. Just grab an address, use it, and walk away. Keep your real inbox for things that actually matter to you.
