Comparison
Sharklasers is a familiar name in disposable email — but it's a branded skin on old infrastructure. Here's how it stacks up against a modern alternative.
Feature Comparison
Why Switch
Sharklasers (powered by Guerrilla Mail) gives you roughly an hour of inactivity before it clears your session. FastTempMail lets you set a custom duration from 1 hour to 3 days, so your address stays active as long as your workflow requires.
FastTempMail lets you manage up to 3 independent addresses at the same time from a single interface. Sharklasers is a single-inbox tool — you get one address at a time with no way to run parallel sessions.
Sharklasers inboxes are not private — the underlying Guerrilla Mail infrastructure operates on a shared public model. FastTempMail generates a dedicated encrypted inbox for each session, accessible only to you.
Sharklasers is a branded front-end on decade-old infrastructure. FastTempMail uses modern tech — real-time SSE delivery, session persistence across tabs, pagination for high-volume inboxes — and a clean interface that works on any device.
Verdict
Sharklasers works for the simplest case — generate an address, receive one email, move on. But the shared public inbox model, fixed session time, and dated interface mean it falls short the moment your needs go slightly beyond that baseline.
FastTempMail handles everything Sharklasers does and adds private encrypted inboxes, multi-session support, custom expiry, and real-time delivery. If you're already using Sharklasers out of habit, FastTempMail is a straightforward upgrade with no tradeoffs.
