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), click Create inbox, and use the address anywhere temporary email is allowed. No account or password: the inbox is bound to the browser session that created it. Messages show as plain text with no remote images, and the inbox expires after 8 days, or sooner if you discard it.
