SecureTempMail review
A flexible disposable inbox service with automation features and a developer plan.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SecureTempMail creates temporary inboxes for sign-ups, downloads, verification codes, and one-off messages. It supports inbox lifetimes from 10 minutes to 24 hours, real-time mail delivery, automatic OTP detection, HTML and attachment viewing, and disposable addresses without registration. Web, Windows, macOS, Linux, Chrome extension, and API access make it suitable for privacy-conscious individuals, testers, and developers who need temporary email workflows across devices.
The free plan provides unlimited disposable inboxes, up to 24-hour lifetimes, real-time inbox access, OTP detection, four rotating domains, HTML and attachment viewing, and ads. Premium costs $39 per year and adds custom and reserved addresses, up to 30-day retention, premium private domains, attachment downloads, no ads, inbox history, and search. Developer costs $190 per year and adds the REST API, webhooks, 100k API requests per month, catch-all domains, programmatic inbox creation, Swagger/OpenAPI documentation, and an email support SLA. Annual pricing is shown for all three plans.
Automation is the clearest differentiator. The API supports inbox creation, message polling, reading, and deletion, while webhooks provide real-time delivery for automated email testing. The Chrome extension adds per-site aliases and autofill, and desktop notifications include an OTP quick-dialog. Sandboxed HTML rendering with scripts disabled adds a defined safety measure when viewing messages. Choose SecureTempMail if you need disposable inboxes plus browser, desktop, or programmatic workflows. A simpler service may suit users who only need short-lived inboxes, while users needing attachment downloads, longer retention, or automation should select the corresponding paid tier.
