Frequently asked questions

The questions people send us most, answered properly. Can't find yours? Get in touch.

The basics

Is Mailfornet free?

Yes. Temporary addresses are free and need no account. If you want addresses that never expire, our optional paid plans add permanent addresses, custom usernames and more storage.

Do I need to sign up?

No. Open the homepage and you'll have a working address a second later. There's no username, password or phone number involved.

Can I pick my own address?

Usually, yes. Type a username before clicking Generate. It has to be 3 to 30 characters long, and a few names like admin or support are reserved. If someone is already using that name, you'll be asked to choose another.

Can I send emails from a temporary address?

No. Addresses are receive-only. If people could send mail from them, the domains would be used for spam within a day and get blocked everywhere.

Timing and expiry

How long does an address last?

10 minutes by default. The countdown on the address card shows exactly how much time is left, and it turns yellow in the last minute.

Can I keep it longer?

Press +10 min on the address card. You can do that a couple of times per address. If you need an address for days or weeks, a temporary inbox is the wrong tool. Use a Gmail alias instead.

What happens when it expires?

The address stops accepting mail, and anything sent to it afterwards bounces back to the sender. The messages that were in the inbox are deleted from our servers within about a minute.

Can I get an expired address back?

Not the messages. They're gone for good. You can create the same username again later if nobody else has claimed it in the meantime, but it starts with an empty inbox.

When something doesn't work

Why didn't my verification email arrive?

In order of likelihood:

  • The site blocks temporary domains. Tap New address or change network, choose another network or domain, and sign up again.
  • The sender is slow. Some services queue their emails. Give it a minute before trying again.
  • The address expired. Check the timer. Anything sent after expiry is rejected.
  • A typo. Use the Copy button rather than typing the address by hand.
The email is blank or looks broken

Press Plain text above the message to see the text version. Codes and links are always readable there.

My addresses disappeared from "My addresses"

That list is saved in your browser, not in an account. Clearing your browser data, using private mode or switching devices will start you with an empty list.

Privacy and safety

Can other people read my inbox?

On our own domains, each inbox is tied to a private access token that lives in your browser. Someone who only knows the address can't open it. External networks such as Guerrilla Mail and Mail.tm have their own rules, so treat those inboxes as public.

Is it safe to open emails here?

Messages are shown in a sandboxed frame that blocks scripts, so an email can't run code on your device. The usual common sense still applies: don't type passwords into links from strangers, and don't open attachments you weren't expecting.

Do you keep my emails?

Only until the address expires. We don't archive messages, read them or use them for advertising. The privacy policy spells out exactly what's stored and for how long.

Should I use this for my bank or social media?

Please don't. You'd lose the ability to reset your password once the address expires. Temporary email is for sign-ups you don't care about keeping.

Gmail aliases

What's a Gmail alias?

Another way of writing your existing Gmail address. Gmail ignores dots and anything after a plus sign, so jane.doe@gmail.com and janedoe+shop@gmail.com both reach janedoe@gmail.com. Our full guide explains it in detail.

Why don't alias emails show up on Mailfornet?

Because they go to your own Gmail account. The generator only creates the address variations. It never sees your mail.

Is my Gmail address sent to your server?

No. The alias generator runs entirely in your browser.
