The record

Purpose: Mailinator provides temporary inboxes and email and SMS workflow testing for developers, QA teams, and businesses.
Email testing: Teams can test email delivery, OTP, MFA, onboarding, password recovery, and other email workflows at scale.
Private domains: Subscriptions include private testing domains, and any address at a private domain can receive test email without pre-creating an inbox.
Automation: The REST API supports inbox and message retrieval, SMS retrieval, message injection, and integration with CI/CD pipelines.
Integrations: Inbound webhooks can accept HTTP POST messages from sources such as alert systems, Zapier, or Twilio and apply configured rules.
SMS testing: SMS messages can be routed to an inbox or the API for automated OTP and 2FA testing, and the page lists SMS numbers at $500 per number per year or $50 per month, including 500 messages monthly.
Public inbox privacy: Public inbox messages are readable by anyone and typically auto-delete after several hours, so the FAQ says not to expect privacy.
Receive-only: Mailinator is receive-only and cannot send email or fill out forms.
Security: Mailinator says web traffic is served over HTTPS, private system email bodies are encrypted at rest, and public system email is not encrypted.
Hosting certifications: The security page lists Linode SOC 1 Type 2, SOC 2 Type 2, HIPAA Type 1, HITECH, and PCI DSS certifications, and DigitalOcean SOC 2 Type 2, SOC 3 Type 2, and PCI DSS.
Support: Documentation is available 24/7/365; the support page says public issue emails are usually answered within 24–72 hours and subscribers receive priority support.
Trial: The pricing page offers a free Business plan trial for two weeks.
Company: The pricing page says Mailinator is wholly owned and operated in the U.S.A., and the site footer identifies Manybrain, Inc.
Founded: 2003
Price from: $79/mo
