Instantaneous Real-Time Synchronization

FastTempBox employs smart polling and Server-Sent Events (SSE) to update your inbox the very moment an external mail server finishes delivery. You never have to frantically hammer the refresh button.

Sandboxed HTML Rendering

Email renderers in traditional webmail clients can be vulnerable to cross-site scripting (XSS) and CSS injection attacks. FastTempBox renders every incoming HTML message inside an isolated, sandboxed viewport with strict origin controls, ensuring external trackers cannot execute code in your browser.

Frequently Asked Questions

Does FastTempBox support attachments?

Yes! Safe attachments (PDFs, images, documents) can be downloaded securely. Executable scripts and malware extensions (.exe, .bat, .php) are automatically blocked for your protection.
