In their own words
SecureTempMail
SecureTempMail provides disposable inboxes for sign-ups, downloads and one-off verifications without requiring an account. Users choose an inbox lifetime from 10 minutes to 24 hours, after which messages are deleted. The receive-only service cannot send email from temporary addresses. It detects verification and login codes for copying, and displays incoming HTML in a sandbox with scripts disabled to neutralize tracking pixels and malicious markup. SecureTempMail says inbound mail uses TLS and opportunistic STARTTLS, and that it does not log IP addresses against inbox activity or build advertising profiles. Its API supports inbox creation, message reading and deletion, and real-time webhooks. The Chrome extension offers per-site aliases, one-click autofill, OTP notifications and a side-panel inbox. Desktop apps are offered for Windows, Apple Silicon Macs and Linux; Intel Macs are not yet supported. The free plan lists unlimited disposable inboxes with up to 24-hour lifetimes and rotating domains, and is ad-supported. Premium costs $39 a year and includes up to 30-day retention, private domains, attachment downloads, no ads, inbox history and search, and priority delivery. The Developer plan costs $190 a year and includes 100k API requests per month, catch-all domains, REST API and webhooks, and an email support SLA.
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.
