Questions people ask
Who can read my messages in tempmailboxes?
Public mailboxes are shared with anyone who has saved access to that address, while private mailboxes belong only to your account and are available on Pro and Developer plans.
How long do messages stay in my mailbox?
Free public messages are kept for 7 days and Plus public messages for 14 days, with higher plans following their own retention; each message expires from its original receipt time, and reading it does not extend that deadline.
Do I need to create a mailbox before I can receive mail?
Yes, you must open the mailbox first and share its address afterward; mail sent to an inactive address is discarded and cannot be recovered.
Can I send email or use my own domain with tempmailboxes?
The service is receive-only and does not send, reply, or forward email, but Pro and Developer plans support private receiving on verified custom domains.
Can I automate verification-code retrieval?
The Developer plan includes an API for private mailboxes with an OTP event stream that watches new arrivals for up to 60 seconds and returns code candidates with metadata and a heuristic confidence score.
