General Questions
What is a temporary email address?
A temporary email address is a disposable, self-destructing email address that you can use for short-term purposes. It works like a regular email — it receives messages, verification codes, and attachments — but it automatically expires after a set period, and all data is permanently deleted.
Is using temporary email legal?
Yes, using a temporary email address is completely legal. It is a privacy tool, similar to using a VPN or private browsing mode. You are under no obligation to provide your permanent email address to every website that asks for one.
Is temporary email safe?
Yes, temporary email is safe for its intended purposes: receiving verification codes, signing up for services you want to try, and protecting your real email from spam. However, you should not use it for sensitive accounts like banking, healthcare, or work.
Can I send emails from a temporary address?
Most temporary email services, including OneTempMail, are receive-only. This prevents abuse while providing the privacy protection you need.
Privacy Questions
Can temporary email be traced back to me?
Temporary email services do not require registration or personal information. There is no connection between the temporary address and your real identity. OneTempMail does not log IP addresses or personal data.
Do you store my emails?
Emails are stored only for the duration of the temporary address lifespan. Once the address expires, all emails and attachments are permanently and irreversibly deleted.
Can someone else read my temporary email?
If someone knows your exact temporary email address, they could potentially access the inbox during its active period. For this reason, choose random addresses or custom names that are not easily guessable for sensitive verifications.
