Close a Temp Inbox vs Delete It: What's the Difference?
27 October 2026 · TempJar
Short answer: closing an inbox puts it aside — you can reopen it. Deleting it removes its messages — and you should only do it when you are sure. Most temp mail services have a single button, usually called delete, and pressing it ends the inbox. TempJar separates the two actions, and confusing them is an easy way to lose messages you actually wanted. This article explains the difference in plain terms, so you press the right button at the right time.
The confusion is understandable. In everyday language, "close" and "delete" sound similar. In an inbox, they are opposites: one is reversible, the other is not. Knowing which is which before you click matters most when the inbox contains a code, a receipt, or a link you might need tomorrow.
What "Close inbox" does on TempJar
Closing an inbox ends your current view of it and shows a notice — but the inbox itself is not deleted. You can reopen it later with the same handle and password, and its messages will still be there, because TempJar does not auto-delete messages. Closing is the right move when you are finished for now but might need the inbox again: you have read the code, you are done with the signup, and you do not want the inbox sitting open on your screen. It is also the safe move on a shared computer: close the inbox when you walk away, so the next person does not see your mail.
Think of closing like shutting a book. The book is still on the shelf, with your place marked. You just are not reading it right now.
What deleting does
Deleting removes messages — yours, individually, or the inbox's contents — and that removal is the end of those messages. Delete a single message you do not need, and it is gone. Delete messages you might need for a return, a receipt, or a second code, and there is no undo, no trash folder to fish them out of, and no support route to restore them. That finality is why deleting should be a deliberate act, not a tidy-up reflex. Before you delete, copy out anything you might need: order numbers, tracking links, codes, deadlines.
The rule: close when you might return; delete only when you are certain you will not need that message again. When in doubt, close — you can always delete later, but you cannot un-delete.
When to use each one
- Close the inbox when you have finished a signup for today, when you are leaving a shared device, or when you want a clean screen without losing the inbox.
- Delete a message when it is obvious junk, a duplicate code, or marketing you have already read and will never need.
- Block a sender when one sender keeps filling an inbox with junk — blocking stops that sender's future mail from cluttering the inbox, without deleting anything you need.
- Abandon a handle when a whole purpose inbox has become too noisy: stop using that handle and create a fresh one, rather than deleting message by message.
How to get a closed inbox back
Reopen it the same way you opened it the first time: go to TempJar, enter the handle and password for that inbox, and it returns with its messages intact. If the inbox was a custom password inbox, it lasts 6 months without an account, or forever in a vault — closing it does not shorten that. If it was a ready inbox, remember it only lasts 24 hours from creation, so a closed ready inbox still expires on its own clock. And if the inbox is in a vault, open it through the vault. The only way a closed inbox truly becomes unreachable is if you forget its password and it is not in a vault — which is why saving the password in a password manager matters more than any button.
What temp mail is NOT for
Do not use a temporary address for banking, government services, password recovery for important accounts, or Discord, or any account you cannot afford to lose. Some sites reject temporary addresses outright, and a lost temp inbox can mean a lost account. Temp mail is for low-stakes sign-ups, trials, newsletters and downloads, where spam is the real cost. If losing access would hurt, use your real email instead.
Quick reference
- Close inbox: reversible, messages kept, reopen with handle + password.
- Delete message: permanent, no trash, copy what you need first.
- Block sender: stops future mail from that sender.
- Abandon handle: stop using it; create a fresh one for that purpose.
