Temp Gmail: What Actually Works
You can't generate a real temporary Gmail address. Gmail addresses only exist as full Google accounts. What you can do is bend your own Gmail with plus addresses, or use a throwaway inbox on another domain. Here is what each one does and doesn't hide.
Checked October 2026 against Google, Microsoft and Yahoo help pages.
What "temp Gmail" sites really give you
Mail sent to an @gmail.com address can only arrive in the Google account that owns it. So when a site hands you an @gmail.com address and shows you its mail, that site, or whoever runs it, owns the account and can read everything delivered to it, including your codes. Often it is one account handed out to many people in dotted or plus-tagged forms.
That is worse than an honest throwaway inbox, not better. Your verification code sits in a mailbox you don't control, alongside other people's, and Google can close the account at any time.
Plus addresses: you+anything@gmail.com
Add a plus sign and any word before the @, and the mail still arrives in your normal inbox. Google documents this for its Workspace accounts, and it works the same on a free Gmail address. You could give a shop you+shop@gmail.com, then set up a filter that labels or deletes anything sent to it.
- It hides nothing. Anyone can remove "+shop" and email you directly. Spam lists do this as a matter of course.
- Some forms refuse it. A few sites reject the plus sign, or quietly strip it. SimpleLogin's FAQ makes the same point.
- It never expires. That is good for an account you keep, since password resets still reach you, and bad if you wanted the mail to go away by itself.
Dots: j.o.h.n@gmail.com
Google says plainly that dots don't matter in Gmail addresses: john.smith@gmail.com, johnsmith@gmail.com and j.o.h.n.smith@gmail.com are one inbox. The same page warns that work and school accounts are different, and there the dots do count. Google also treats @googlemail.com as the same as @gmail.com.
Dotted versions are even weaker than plus addresses for privacy. Gmail sees them as identical, so you can't filter on them, and anyone can take the dots out.
Which to use when
| Option | Hides your Gmail | Lasts | Best for |
|---|---|---|---|
| Plus address | No | For good | Sorting mail from accounts you keep |
| Dotted address | No | For good | Nothing much, beyond forms that dislike plus signs |
| Temp mail inbox | Yes | While the tab is open | One-off codes, downloads, a quick look at a site |
| Alias service | Yes | Until you turn it off | Accounts you keep but don't fully trust |
When a temp mail address is the better choice
Use a temp mail inbox when you need one code or one link and nothing after it: a download behind an email form, a forum you want to read once, a free trial you won't keep. The site never learns your Gmail, so it can't add it to a list or lose it in a breach.
Don't use one for anything you'll need to log back in to. Password resets go to the address on the account, and a temporary inbox doesn't last: this browser keeps it for 7 days after your last visit, and only while you have the key. For those, a plus address on your own Gmail is fine, and an alias service is better if you'd rather the site never saw your real address. Our alias vs temp mail guide compares them.
Outlook and Yahoo
Outlook.com lets you add an alias to your Microsoft account: a second address that delivers to the same inbox. Microsoft caps how many you can add each year, so they are for keeps, not throwaways.
Yahoo has gone further than Google. Its disposable addresses look like nickname-keyword@yahoo.com, you can send from them, and you can delete one when it starts getting spam. Yahoo Mail Plus gives you up to 500. Where Plus is sold, free users can try up to 3.
Questions
Is there a free temp Gmail generator?
Not a real one. Only Google can create an @gmail.com address, and it only does so as a full Google account. A site that shows you mail for an @gmail.com address it handed you is reading an inbox it controls, so anyone with access to that site can read the same mail.
Does a plus address hide my real Gmail?
No. you+shop@gmail.com shows your real address to anyone who deletes the part from the plus sign to the @. It is useful for sorting and filtering mail, not for privacy.
Does the dot trick give me new Gmail accounts?
No. Google treats john.smith@gmail.com and johnsmith@gmail.com as the same address, so every dotted version lands in one inbox. Some sites count them as different addresses, but they are still your account.
Can I make a second Gmail account just for sign-ups?
Yes, and it is a real, lasting inbox. Google may ask for a phone number while you create it, and it limits how many accounts one number can verify.
What about a temporary Outlook or Yahoo address?
Outlook.com lets you add aliases to your Microsoft account, within limits. Yahoo offers disposable addresses with Yahoo Mail Plus, and a free trial of 3 where Plus is sold. Both stay linked to your real account, so they suit accounts you keep rather than one-off sign-ups.
