Why Switch

Where FastTempMail pulls ahead.

Faster, cleaner experience

Guerrilla Mail's interface dates back to the early 2010s — cluttered, slow to load, with heavy ads that compete for your attention. FastTempMail loads in under a second with a focused UI where ads don't get in your way.

Up to 3 inboxes at once

Need to test multiple accounts? FastTempMail lets you manage up to 3 disposable addresses in one tabbed session. Guerrilla Mail only supports one at a time.

You control the expiry

Guerrilla Mail gives you a fixed window. FastTempMail lets you set any expiry from 1 hour to 3 days — matching how long you actually need the address.

Genuine zero-retention policy

Emails auto-delete on expiry with no backups. FastTempMail collects no personal data, no analytics fingerprinting, no selling to third parties.

Verdict

The bottom line.

Guerrilla Mail was groundbreaking for its time, but temporary email has moved on. The interface is cluttered with ads, the feature set hasn't grown in years, and there's no real privacy policy worth reading.

FastTempMail gives you a distraction-free inbox, multi-session support, flexible expiry, and a genuine commitment to not storing your data. If you're still using Guerrilla Mail out of habit, it takes about 10 seconds to switch.
