DummyInbox

DummyInbox is a free temporary email service designed to help people receive messages without sharing their everyday email address. Users can create an inbox in seconds by choosing a mailbox name, selecting a suggested name, or generating a random address. No account, password, phone verification, or setup is required.

Incoming messages appear in the inbox, which refreshes automatically every ten seconds. DummyInbox is receive-only and cannot send email; messages are kept for 48 hours before being deleted automatically. Because anyone who knows an inbox address can open it, the service recommends using random addresses and avoiding accounts that matter.

Features include support for HTML and plain-text messages, downloadable attachments, and access to raw message source. Remote tracking images are blocked unless the user chooses to load them. The service is intended for tasks such as testing email flows, trying services, and keeping sign-up messages separate from a personal inbox.

DummyInbox also lists an API, FAQ, support, and privacy policy, and says its features are free with no ads or paid tier
