Questions about Mailfast

What is Mailfast?

Mailfast is a web-based temporary email service whose inbox self-destructs after 60 minutes. It generates a new address as soon as someone visits, needs no signup, and shows incoming emails in real time, which the reviewer says keeps a real inbox safe from spam and phishing.

Is Mailfast free?

Mailfast is free to use, with a single Free plan at $0. Toolio found no paid plan on the vendor's site in September 2026, and no registration or personal information is needed to start using it.

How long does Mailfast keep emails?

Mailfast keeps emails for only an hour before deleting them automatically. The reviewer counts this as a privacy strength but also as a limit, since it makes the service unsuitable for long-term archiving or for storing important messages.

What are the limitations of Mailfast?

Beyond keeping messages for only an hour, Mailfast does not allow sending or receiving email with attachments, and emails cannot be forwarded to another address after they arrive. The reviewer says it is great for one-time signups but not ideal for ongoing communication.

Who is Mailfast best for?
