What stays the same

Both choices can receive legitimate mail. Neither guarantees anonymity, trustworthy senders or secure accounts. You still need unique authentication and a dependable recovery plan.

What changes

With the right address lifetime, you can apply this principle: match the route’s lifetime to the longest obligation in the relationship. With making every route permanent, a disposable address can vanish before recovery, returns or warranties are complete. The value is containment rather than invisibility.

A separate route changes the size of the clean-up.

How to choose

Use the simpler option when the consequence is small and the relationship is short. Choose stronger separation when recovery, public exposure or cross-context matching would matter.

  • Estimate recovery needs
  • Allow for disputes
  • Extend before expiry
  • Make valuable routes durable

The honest caveat

Temporary should describe the relationship, not a guess made too early. Make the decision for the risk you actually have, not the most dramatic risk you can imagine.

Give the next relationship its own route.
