Comparison
Throwam handles the basics — but basic isn't always enough. Here's where the two services diverge when your workflow needs more.
Feature Comparison
Why Switch
Throwam uses a fixed short-lived session with no customisation. FastTempMail lets you choose your own expiry — from 1 hour up to 72 hours — so the address stays active exactly as long as your task requires.
FastTempMail supports up to 3 simultaneous inboxes from a single tabbed view. Throwam is a single-session, single-inbox tool. If you're signing up on multiple sites or running parallel tests, FastTempMail handles it cleanly.
FastTempMail encrypts every inbox end-to-end. Your emails are only readable by the session that generated the address. Throwam does not offer inbox encryption, leaving message content potentially accessible server-side.
FastTempMail uses Server-Sent Events to push new emails to your inbox the moment they arrive. There's no need to manually refresh. Throwam relies on polling, which introduces delay and requires active page refreshes to check for new mail.
Verdict
Throwam is adequate for the simplest disposable email tasks — get an address, receive one verification email, done. But it offers nothing beyond that: no control over expiry, no multi-inbox, no encryption, no real-time delivery.
FastTempMail covers the same baseline while adding the features that matter in practice. Custom expiry means your address lasts exactly as long as you need. Three simultaneous inboxes handle parallel workflows. End-to-end encryption means your emails stay private. For anything more than a single quick verification, FastTempMail is the better tool.
