Temporary Email vs Masked Email Forwarding
Compare reading mail in a disposable inbox with forwarding through a separate masked address.
Masked email separates the visible address but keeps a forwarding relationship
A masked-email service can give a site a different address while forwarding messages into your real mailbox. Temporary email instead keeps the message in its own short-lived inbox and does not need to forward it into your durable mail history.
Forwarding is useful when messages must keep coming
A managed masked address can often be disabled later while preserving the convenience of one main inbox. That makes it a better fit for ongoing services where you still want separation from the public address.
A disposable inbox avoids creating a long tail
For a short verification flow, forwarding every message into the permanent mailbox can defeat part of the reason for separating the task. A temporary inbox is cleaner when there is no future relationship to preserve.
Forward or finish
Use masking when you want an ongoing controllable route to your real inbox; use temporary mail when no ongoing route is needed.
