Can Temp Mail Send Email? Sending and Reply Limits
TempInbox cannot send email or reply to messages. It is a receive-only temporary inbox for verification codes, links, and other incoming email when the sender accepts the address and delivers the message. Other services may offer sending; check their current features and limits.
TempInbox cannot send email or reply to messages. You can receive verification codes, magic links, and confirmation emails when the sender accepts the address and delivers the message. Other temporary email providers may support sending; their features and limits differ.
Can you reply to an email in TempInbox?
No. TempInbox has no compose, reply, forwarding, or outbound SMTP feature. Copying a sender address or opening your regular mail client does not send from your TempInbox address.
What can a receive-only temporary inbox do?
It can receive email-based verification codes, account activation links, trial confirmations, and messages for manual QA. It does not receive SMS codes or guarantee that every website accepts temporary addresses.
To try a browser workflow, open TempInbox, generate an address, and use it in a form that accepts disposable email. Read the incoming message and use its code before the sender's expiry window ends. See the email verification code guide.
What should you use if you need to send email?
Choose a mailbox that explicitly supports outbound sending and replies. If you want to hide your primary address, check whether an alias provider supports replies, new outbound messages, or only forwarding; these are different capabilities.
| Your task | What to use or check |
|---|---|
| Receive a short-term verification email | TempInbox, if the sender accepts the address and delivers the message |
| Compose and send a new email | A mailbox with outbound sending |
| Reply without exposing your primary address | An alias service with supported reply routing |
| Inspect mail sent by your own application | A controlled mail-capture or sandbox system |
A separate mailbox can keep conversations out of your primary inbox, but it does not guarantee anonymity. Check the provider's authentication, logging, retention, and recovery features. For the difference between the service models, read temporary email vs email aliases.
Does keeping an inbox let you send from it later?
No. Browser-saved access does not enable sending or replies. TempInbox has no 10-minute countdown, but it does not guarantee a fixed inbox lifetime or permanent message storage. Browser-saved access and server-side retention are separate; cleanup policies still apply.
Clearing site data can remove access without immediately erasing server-side messages. Read the TempInbox Data Retention Policy. Use a durable authenticated mailbox for ongoing correspondence or account recovery.
Why has my verification email not arrived?
A missing message can result from address rejection, a sender-side failure, delivery delay, or selecting the wrong inbox. TempInbox does not promise a delivery time. Follow the missing verification email checklist.
