In their own words
Mailinator
Mailinator provides temporary inboxes and tools for testing email and SMS workflows. Developers, QA teams, and businesses can use it to check delivery for OTP, MFA, onboarding, password recovery, and other email processes at scale. Paid subscriptions include private testing domains, where messages can arrive at any address without creating an inbox first. The REST API retrieves inboxes, messages, and SMS, injects messages, and connects with CI/CD pipelines. Inbound webhooks can accept HTTP POST messages from sources such as alert systems, Zapier, or Twilio, then apply configured rules. SMS can be routed to an inbox or API for automated OTP and 2FA testing. The free public inboxes are readable by anyone, and messages typically auto-delete after several hours. Mailinator is receive-only: it cannot send email or fill out forms. The Public - Free plan is free to use without sign-up. Business costs $79 a month billed yearly; a two-week Business trial is listed. Other plans include Verified Pro at free, Business Plus at $159 a month billed yearly, and Enterprise at a price agreed with the maker with custom pricing.
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.
