In their own words
TempInbox
TempInbox is a free web service for temporary email inboxes without signup. It is intended for verification messages, trials and low-trust registrations, with developers, QA teams and privacy-conscious users among its stated audiences. One browser can hold up to three inboxes, and access is saved in that browser. The Free plan costs nothing and has no 10-minute timer, but inbox lifetime is custom. Messages may be soft-deleted and later removed in scheduled batches, so long-term storage is not guaranteed. The browser interface lets users view, download and clear messages, including attachments. Hosted TempInbox is receive-only: it has no sending, replies or forwarding, and no supported public API or SDK. It works in Android and iPhone mobile browsers without an app. The maker describes privacy and security as best-effort and warns that messages may be exposed, delayed, removed or inaccessible. It advises against banking, medical, legal, payroll and other high-stakes accounts requiring lasting confidentiality.
TempMaily
TempMaily provides disposable email inboxes for receiving verification codes and signup mail through web and API access. Its free inbox is created without signup, a password, or personal details, and messages appear in the browser as they arrive. Mailboxes are receive-only, so they cannot send email, although incoming messages can include attachments. The free plan permits one shared-domain address at a time; the inbox and its messages are permanently deleted 24 hours after creation, with transient storage and ads. Premium supports up to 10 addresses, custom and dedicated domains, long-term or permanent addresses, and 2GB of email storage. It also adds a REST API and MCP server for programmatic inbox creation and message reading. The MCP server works with Claude Desktop, Claude Code, Cursor, and MCP-capable agent frameworks. Premium costs $7.50 a year when billed annually ($90/year), or $9.90 a month. HTTPS, HTML sanitization, sandboxed rendering, disabled scripts, and blocked remote images are listed protections.
