Temp mail vs email alias: which should you use?
Genmail positions temporary email as a short-lived receiving inbox for one-off signups, while email aliases forward to a primary mailbox for ongoing control; the page explains when each model fits.
Both cut spam, but they solve different problems. One disappears; the other hides your real address while keeping a long-term lane open.
Temp mail = minimal commitment
Ideal when you never want to hear from the sender again after you grab a code or file.
Aliases = durable control
Great when you still need receipts, password resets, and support threads tied to one masked address.
Mix both deliberately
Many people use Genmail for sketchy signups and aliases for subscriptions they actually care about.
How a temp mail inbox behaves
Genmail gives you a standalone mailbox that receives messages until it expires. Nothing forwards to Gmail or Outlook unless you manually copy content—you are intentionally isolating that relationship.
How an email alias behaves
Providers like iCloud Hide My Email or Firefox Relay create an address that forwards into your real inbox. You can usually disable or rotate the alias later, but the mail still lives inside your normal mail client ecosystem.
Quick decision framework
If the interaction lasts minutes, temp mail wins. If it lasts months or involves money and recovery paths, an alias or real address is safer. When in doubt, ask whether losing access to that inbox tomorrow would cause a problem—if yes, skip disposable.
