Is temporary email safe to use?
Yes, for its intended purpose: receiving throwaway mail like verification codes and confirmations. Because there's no account, there's nothing to breach. The key caveat is that an unprotected inbox is semi-public — anyone typing the same name sees it — so never route banking, medical, or password-reset mail through it. For anything sensitive, use your real inbox or lock the inbox with fmail's Protect feature.
Can I send email from a temporary address?
No. fmail and most temp-mail services are receive-only — they exist to catch incoming mail, not to send it. This is also what keeps the service clean and its domains trusted. If you need to send, use a real email provider.
How long does the mail last?
On fmail, mail is kept for 12 hours and capped at 50 messages per inbox, after which older messages drop off automatically. That window is long enough to grab slow-arriving codes and come back to a confirmation link later the same day, while still being fully disposable.
Do I need to sign up or install anything?
No. There's no registration, no password, and nothing to install. Open the site, and an inbox is already yours. The address itself is all that's needed — the inbox is created automatically when mail arrives.
Is it really free?
Yes, completely free with no account and no catch. You can pick any name across 26 domains and read mail live at no cost.
Can someone else read my inbox?
If it's unprotected, yes — anyone who guesses the same username on the same domain lands in the same inbox. Treat addresses as semi-public. If you need privacy, use the Protect option to put a permanent password on a specific inbox.
Do attachments work?
The message body is readable, but attachments aren't displayed. If you need a file, ask the sender to share a link instead.
Why are websites sometimes blocking disposable addresses?
Some sites try to block known temp-mail domains to prevent abuse. Because fmail offers 26 domains, you can simply switch to another one if a particular domain is rejected.
Can I use temp mail for developer testing?
Absolutely — it's ideal for QA. There's a public, no-auth REST API so you can automate signup-and-verify flows in scripts and CI. See our developer guide for examples.
Is using disposable email legal?
Yes. Using a disposable address for privacy, testing, and avoiding spam is perfectly legitimate. Just don't use it to evade bans, commit fraud, or abuse services — that's on you, not the tool.
