Hi Product Hunt! 👋 We built MailSandbox because we were tired of screenshotting local email tests. Our fake SMTP sandbox allows you to catch and inspect emails sent by your websites or application environments without risking them ever hitting a real user's inbox. Paste the SMTP credentials we provide, into your app config, and we instantly capture the traffic. Why MailSandbox? Most legacy tools feel clunky or are overpriced. We wanted a modern UI/UX that our clients will actually use.
