Clear answers about what happens before and after you receive mail

Yes, as long as the sender allows delivery to the current domain. The code will appear in your inbox. Some platforms block disposable email addresses outright; repeatedly creating new ones usually will not help. Use a long-term address that follows their rules instead.

The message may still be with the sender or in an intermediate queue. Check the address, wait a minute or two, and refresh manually. Repeatedly requesting verification codes can trigger rate limits and make new messages arrive even later.

A new address is valid for 3 hours by default. You can extend it by 3 hours at a time, up to a maximum total lifespan of 24 hours from creation. Once the countdown reaches zero, the old address cannot be restored, and mail sent to it will not be transferred.

No. As long as your credentials are still valid, the same browser will restore your current address. A new inbox is created only when you switch addresses or the current address expires.

The disposable inbox indicates whether the original message included attachments, but it does not store the attachment contents. For contracts, receipts, or downloadable files, use permanent forwarding or an email address you control long term.

No. It only reduces exposure of your real email address. It does not hide your network, browser, or other information you submit to third-party websites, and it does not replace your legal or compliance obligations.

We don’t recommend it. Use a stable address and strong authentication for banking, payments, government services, work, and any account you may need to recover long term. Otherwise, an expired address could permanently remove your recovery route.

A forwarding alias is a better fit when you expect future messages, need attachments, or want a separate address for each service. You can pause or delete it and keep limited-term archives, but it still does not replace the ultimate control of your real email account.

Do not click suspicious links or reply to the sender. You can delete an individual message and send evidence of abuse with the necessary message identifiers to support@tempsender.com. Do not forward passwords or complete verification codes.
