Temporary Email vs Plus Addressing (+tag)
Compare a separate temporary inbox with tagged versions of an existing mailbox address.
The +tag still belongs to your main mailbox
Plus addressing changes the local part of an existing address, such as name+shop@example.com, while mail still lands in the underlying mailbox. A temporary inbox creates a separate recipient context that does not need to expose the base address at all.
Plus addressing is excellent for sorting
Tags can separate newsletters, tests or signups while keeping everything inside one mailbox. The limitation is privacy: the base address is usually visible in the tagged form and the relationship remains tied to the long-lived account.
Temporary email is better when the relationship should end
For a one-off confirmation or short low-risk task, a separate temporary address can keep that sender away from your normal inbox. The trade-off is that you should not depend on the address for future recovery.
Choose by purpose
Use +tags when you want organization inside a durable mailbox; use a temporary inbox when you want the address relationship itself to be short-lived.
