Tempburn

Tempburn is a free temporary email service for one-off signups, verification codes and quick inbound email tests. Pick an address length (8–20 characters before the @), click Create inbox, and use the address anywhere temporary email is allowed. There is no account or password: the inbox is bound to the browser session that created it, so knowing the address alone doesn't let anyone read your mail. Messages show as plain text with no remote images or auto-opened links, and the inbox expires after 8 days, or sooner if you discard it.

Key features:

• No signup, no password
• Choose 8–20 characters before @
• Inbox private to the browser session that created it
• Auto-expires after 8 days; discard any time
• Plain-text view, no remote images or auto-opened links
• Receive-only (no sending or forwarding)

Tempburn is completely free. It is not a bulk signup tool. Try it at tempburn.com.
