10 Minute Temp Email vs 1SecMail

10 Minute Temp Email is a free web inbox for receiving short-lived messages, including one-time confirmations and authorized signup-flow testing. A mailbox lasts exactly 10 minutes, or 600 seconds, from creation; after expiry, access ends and the mailbox cannot be recovered. No account or payment is required. The inbox is receive-only, so users cannot send, reply to, or forward email. Listed safe attachments include images, PDF, text/CSV, and ZIP files; unsupported or oversized files are blocked, and HTML email is sanitized. Mailbox data is scheduled for deletion after expiry or manual deletion. Access uses an HttpOnly session cookie, while the raw token is not stored in the database. The service uses Cloudflare Workers, D1 metadata storage, and a private R2 bucket for message bodies. It may show Google AdSense ads and use Google Analytics. It is intended for low-stakes permitted forms and authorized testing, not sensitive accounts or bypassing disposable-address restrictions.

1SecMail provides temporary disposable email for sign-ups, with mailbox creation that does not require registration or personal information. Users can send and receive messages, create custom aliases, and receive attachments to download before they expire. Its guide says addresses and related communications are usually erased automatically after 24 hours. The service is available on web and Android, and a Chrome extension provides access to temporary email. Developers can use published API documentation covering domains, mailbox creation and management, message retrieval, and attachment downloads; however, the API-key feature is currently under development. Premium offerings list additional domains, inbox records, saved messages, attachment viewing, and support. The Premium page also advertises 100MB storage and no ads. A free plan is available; Standard costs $4.99 a month, and paid plans start at $4.99 a month. 1SecMail cautions that public temporary addresses are not suitable for sensitive or financial information.
