Email Generator FAQ
Direct answers to the questions people most often ask about using a free email generator. If your question isn't here, the dedicated guides linked at the bottom cover everything in depth.
Is using an email generator legal?
Yes, in every jurisdiction we know of. Receiving mail at an address you control is not a regulated activity. What you do with that address might be regulated — for example, signing up to a service while pretending to be someone else may violate that service's terms — but the tool itself is just an inbox.
Is it safe?
Reading mail in a temporary inbox is safer than reading the same mail in your personal one, because the address has no relationship to your identity. The risks that do exist:
- Anyone who guesses the address can read its inbox. Don't pick obvious usernames on popular domains for anything sensitive.
- Don't click links to "verify" your real bank or government services through a generated address — those services should never have your generated address in the first place.
- Attachments are scanned but not deeply inspected. Treat unknown attachments the same way you'd treat them in any inbox.
Does mail really arrive?
Yes — every domain in the dropdown has a real MX record pointing at our mail server. The server uses standard SMTP. Mail typically appears in your browser within 1-3 seconds of the sender clicking Send.
If you've waited longer than 10 seconds, something is wrong: either the sender hasn't sent yet, or the domain you picked is on the sender's blocklist (in which case nothing was attempted), or there's a delivery delay on the sender's side (rare).
Can sites detect that the address is generator-issued?
Big sites maintain blocklists of known email-generator domains. If one of our domains is on the list, sign-up fails. Switch to a different domain from the dropdown — at least one of our active domains is almost always missing from any given blocklist. See avoid spam with an email generator for tactics.
Do I need to sign up to use it?
No. No account, no password, no phone number, no card. Open the homepage, the address is already there.
Can I get the same address back later?
Yes, within the retention window. The address lives on the URL — bookmark it, or use the Recent Mail panel which remembers your last-used addresses in your browser's localStorage. After the retention window expires (see how long do generated emails last), the address is recycled.
Can I send mail from a generated address?
No. This is a receive-only service. The address has no SMTP submission credentials — there's no "compose" button anywhere. For outgoing mail, use your real account.
Are my messages encrypted?
Messages are stored at rest in our database; they travel between our server and your browser over HTTPS (TLS). SMTP delivery from the sender uses opportunistic TLS where the sender's server supports it. End-to-end encryption (PGP/S-MIME) is not provided — if you need that, the generator model is the wrong fit.
Who can see my messages?
Anyone with the address can open its inbox. That includes you, your colleague if you shared the URL, anyone who guesses the username. We don't sell access; we don't show ads inside messages. Internal access is limited to operators for abuse-investigation purposes. See email generator privacy guide.
Can I attach files in an outgoing message?
You cannot send. You can receive attachments — PDFs, ZIPs, images. They appear under the message body with a download link.
What if the address I want is already in use?
If two people independently pick the same custom username on the same domain, they share the inbox. This is inherent to generated addressing — there's no registration step that would prevent collision. For sensitive sign-ups, pick a less obvious username or let the random one stand.
Is there a mobile app?
No. A browser tab is the whole UI — works on desktop and mobile browsers identically. No app to install, nothing on your home screen, nothing to update.
Can I use it for two-factor authentication (2FA)?
For services you care about — no. The address will be recycled; if someone else gets it later, they can pass 2FA on your account. For services you don't care about (one-off sign-ups), 2FA via generator-issued mail works fine because you'll never log in again anyway.
Will this work on Gmail / Microsoft sign-up?
No. Major free-mail providers explicitly block generator domains. Use real services for real accounts — generator-issued is the wrong tool for "I want a Gmail without giving Google my phone".
Can I use my own domain?
Not on this service. We host our own domains; you cannot bring yours. If you need a custom domain for permanent use, that's a different category of service. See custom domain email generator guide for the trade-offs.
Do you support international (Unicode) usernames?
Receiving — yes, partly. The username part (before the @) is restricted to ASCII for compatibility; the domain part can be Unicode (IDN). If a sender uses a non-ASCII From address, we display it correctly.
What if the site demands a confirmation link?
The link arrives in your message body the same as any other. Click it — the verification happens on the sender's side, not ours.
What if I lose access to the tab?
If you bookmark the URL or remember it, you can come back. The address has no password — anyone with the URL has access during the retention window. Don't share the URL with strangers; treat it like a one-time secret.
Is it free? Are there hidden charges?
Completely free. No paywall, no premium tier, no surprise charges. We're funded by ads on the homepage (no ads inside messages). See email generator best practices for ethical use.
