Temporary Email vs a Separate Secondary Email Account
Choose between a short-lived inbox and a second mailbox you plan to keep and manage.
Both separate mail, but only one is meant to stay
A secondary email account gives you a durable second identity with login, recovery and long-term history. A temporary inbox removes most of that management because it is designed for a short task and then to stop mattering.
A second account earns its overhead when continuity matters
Shopping receipts you may need later, subscriptions you actively manage, communities you revisit and accounts with password recovery can justify a dedicated secondary mailbox.
Temporary email removes maintenance for disposable interactions
If the sender only needs to deliver one code, link or download confirmation, creating another permanent account can be more identity and storage than the task deserves.
Lifetime is the deciding factor
Choose a secondary account for a category you intend to maintain; choose temporary email for a relationship you intend to finish.
