SecureTempMail vs Tempr.email

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.

Tempr.email provides disposable email addresses for receiving messages without giving out a personal inbox address. Users choose an alias and domain, then read incoming mail without registering. The service lists 61 domains, with more added regularly, and accepts text and HTML email, including file attachments. Messages are automatically deleted after 30 days, though users can delete them sooner. A free account adds password protection for selected mailboxes, custom domains, saving or printing messages, header viewing and bookmark access. Premium access enables sending, forwarding and replying, as well as RSS and ATOM notifications for new mail. Tempr.email is a web service that also works in a responsive mobile browser. Listed use cases include registrations, downloads, surveys, short-term test accounts and newsletter testing. The service advises using a regular address for banking and important long-term accounts. It cautions that complete anonymity cannot be guaranteed, and that mailbox security partly depends on alias guessability; password protection also has limits. The free plan costs nothing and retains messages for 30 days.
