FlashMail is a fast, privacy-friendly disposable email service designed to help you protect your real inbox from spam, tracking, and unnecessary clutter. We believe everyone deserves simple tools to stay safe online—without giving up convenience.
Unlike most platforms, we don’t ask for registration, passwords, or personal details. When you click “Create Inbox”, we generate a random address that stays active for 20 minutes. During that time, it can receive messages instantly and anonymously.
Our entire infrastructure is built to be lightweight, serverless, and secure. FlashMail does not use cookies, does not track your activity, and does not store messages beyond their lifespan. It’s free, open by design, and supported by minimal third-party ads.
By using FlashMail, you agree to use the service only for lawful purposes. This service is intended for personal use, such as testing websites or avoiding spam.
You may not use FlashMail to send unsolicited messages, abuse other services, commit fraud, or engage in illegal activity. Any misuse may result in access being restricted.
FlashMail is offered “as-is”, with no guarantees about uptime, email delivery, or long-term availability. We may block, limit, or discontinue access at any time without notice.
