OpenInbox vs Mailinator
Mailinator is a well-known disposable email service, but it has significant privacy and feature limitations. See why thousands of users are switching to OpenInbox.
What Is Mailinator?
Mailinator is one of the oldest disposable email services on the web. It provides public inboxes where anyone can check email sent to any @mailinator.com address. While this makes it simple to use, the public nature means anyone can read your emails — creating serious privacy and security concerns.
