SecureTempMail

Purpose: SecureTempMail provides disposable inboxes for sign-ups, downloads, and one-off verifications without requiring signup.
Inbox expiry: Users can choose inbox lifetimes from 10 minutes to 24 hours, and messages are deleted when the timer expires.
Receive-only: The service is receive-only and does not support sending email from temporary addresses.
OTP detection: Verification and login codes are automatically detected and surfaced for one-tap copying.
Email rendering: Incoming email HTML is rendered in a sandbox with scripts disabled to neutralize tracking pixels and malicious markup.
Encryption: The Trust Center says the service uses TLS and opportunistic STARTTLS for inbound mail.
Data handling: SecureTempMail says it does not log IP addresses against inbox activity or build advertising profiles, and deletes inboxes and messages on expiry.
Developer API: The API supports inbox creation, message reading, deletion, and real-time webhooks; the Developer plan includes 100k requests per month.
Desktop app: A desktop app is offered for Windows, Apple Silicon Macs, and Linux; Intel Macs are not yet supported.
Browser extension: The Chrome extension offers per-site aliases, one-click autofill, OTP notifications, and a side-panel inbox.
Use cases: The site lists sign-ups, one-time purchases, content downloads, gaming and forums, team vendor sign-ups, and QA or end-to-end testing as use cases.
Support: The contact page lists separate email addresses for general support, security and privacy, and API or partnership inquiries.
Service guarantee: The site says inboxes and messages are provided as-is without a guarantee of delivery, accuracy, or retention.
