Mailinator review

Mailinator is best known for its public inboxes: pick any name at mailinator.com and you can read mail sent to it with no sign-up. That makes it handy for a quick throwaway, but anyone who guesses the same name can read the same mail, so it is not private. Mailinator's real business is email and SMS testing for QA and engineering teams. A Verified Pro tier, $0 with verification, adds unlimited private inboxes and 1 private domain with 10MB of permanent storage. The Business plan costs $79 a month billed yearly and adds 50MB of permanent storage, up to 20 emails a second, team management, SSO support and pay by invoice. Business Plus is $159 a month billed yearly with 3 private domains, and Enterprise starts at $699. API access, webhooks, routing rules and load testing sit on the paid tiers. For personal privacy, the alias services higher on this list are cheaper and safer.
