Gmail Generator: Alternate & Temporary Gmail Addresses

Short answer: A Gmail generator doesn't create new Gmail accounts. It takes the address you already have and adds dots (j.ohnsmith@gmail.com) or a plus tag (johnsmith+shop@gmail.com). Google confirms both versions still land in your normal inbox, so you can make as many as you like by hand, no tool needed. If you want an address that isn't tied to you at all and disappears afterwards, you need a temporary (disposable) email service instead. That's fine for a one-off download, but never for anything you'll need to get back into later.

Below: how the dot and plus tricks work according to Google's own help pages, how to make and filter your own variations, what temporary "use and throw" email services are good for, and where all of this stops working.

What a Gmail generator actually does

Search for "Gmail generator" and you'll find two quite different kinds of tool sharing one name:

Alias generators ask for your Gmail address and list dotted and plus versions of it. Everything sent to those versions arrives in your own inbox. Mailmeteor's and Aspose's Gmail generators, two of the best-known, work this way.
"Temp Gmail" sites hand you an inbox they control and show you whatever arrives there. That's a disposable email service with a Gmail-looking address, and it's a different thing with different risks (more on that below).

Here's how the main options compare:

Option	Where mail goes	Good for	Main limit
Dot variation (jo.hnsmith@gmail.com)	Your inbox	Sign-ups where you might want to filter later	Easy to undo: anyone can remove the dots
Plus address (johnsmith+news@gmail.com)	Your inbox	Seeing who shared your address; auto-sorting with filters	Some sign-up forms reject the + sign
Temporary (disposable) email service	Someone else's inbox, usually for minutes or hours	One-off downloads and confirmations	You lose the address, and with it any account you made
Forwarding alias (Hide My Email, Firefox Relay)	Your inbox, via a random address	Sign-ups you may want to switch off later	Some sites refuse these addresses
A second Google account	A separate inbox	A genuinely separate identity, such as a side project	One more account to secure and check

The Gmail dot trick

Gmail ignores dots in the part of the address before the @. Google's help page puts it plainly: if your address is johnsmith@gmail.com, you own all dotted versions of it, such as john.smith@gmail.com and j.o.h.n.s.m.i.t.h@gmail.com. Mail sent to any of them goes to the same inbox.

A few things follow from that, all confirmed by Google:

Nobody else can register a dotted version of your address. They get an error saying the username is taken.
Nobody else receives mail sent to a dotted version. It's all yours.
Capital letters don't matter either: Gmail usernames aren't case-sensitive.
It only works on @gmail.com addresses. On a work or school account (yourname@yourcompany.com), dots do change the address.

How many variations can you make? Every gap between two letters can hold a dot or not, so a username with n letters has 2^n-1 versions. An eight-letter name like johnsmit already gives 128.

The catch: because Gmail treats them as one address, so can anyone else. A website that wants to stop duplicate sign-ups can strip the dots in a single step. Dots are best thought of as a labelling trick, not a way to look like a different person.

Plus addresses: a temp Gmail without dots

If you'd rather not play with dots, use a plus sign. Add + and any word after your username, and Gmail still delivers to you. Google's own example: janedoe+school@gmail.com, janedoe+notes@gmail.com and janedoe+important.emails@gmail.com all reach janedoe@gmail.com. Google Workspace accounts support the same thing (cassy+news@yourcompany.com, in Google's example), so plus addresses also work on many work addresses where dots don't.

Plus addresses are more useful than dots for one reason: the tag stays visible in the To line. Use yourname+shoeshop@gmail.com when you sign up somewhere, and if spam later arrives at that exact address, you know who passed it on. You can also filter by it.

Two limits. Some sign-up forms wrongly reject addresses with a + in them. And since the tag is plain text, a sender can remove it and reach your main address anyway, so it helps you sort and trace mail, not hide.

How to make your own Gmail aliases (no generator needed)

Start from your address, for example yourname@gmail.com.
Pick a tag for each purpose: yourname+news@gmail.com for newsletters, yourname+shopping@gmail.com for stores, yourname+trial@gmail.com for a free trial you're testing. Google suggests exactly this kind of scheme.
If a form rejects the + sign, use a dotted version instead (your.name@gmail.com).
Write down which alias you used where, or let your filters do it for you (next section).

That's all an alias generator does. Typing it yourself has one advantage: you don't hand your address to a third-party website just to get a list of strings back.

Filter or switch off an alias in Gmail

Filters are what make aliases worth using. They let you label, archive or delete everything sent to one alias:

Open Gmail on a computer. In the search box at the top, click Show search options.
In the To field, type the alias, for example yourname+news@gmail.com.
Click Create filter.
Choose what should happen: apply a label, skip the inbox (archive it), star it, forward it or delete it.
Click Create filter again.

If one alias starts attracting spam, edit its filter to Delete it. That's the closest Gmail gets to switching an alias off. You can change or remove filters later under Settings > See all settings > Filters and Blocked Addresses. Our guide to creating rules in Gmail goes further into filters.

Use and throw emails: temporary and disposable addresses

A use and throw email (also called a throwaway, temporary, disposable or "10-minute" email) is an address you use once and abandon. Disposable email services create one on the spot: you open the site, get a random address and an inbox on the page, use it to receive a confirmation code or download link, and the address expires after a set time, from minutes to a few days depending on the service. People often look for these by brand names such as throwemail, throwinbox or trashinbox, but they all work the same way.

They're reasonable for:

A one-time download or white paper behind an email form.
Reading an article or trying a tool you'll never come back to.
Keeping a site you don't trust from ever having your real address.

And they're the wrong tool for anything you might need again:

You can't recover the account. Password resets and security codes go to the address. Once it expires, whatever you signed up for is effectively lost.
The inbox isn't private. On many of these services, anyone who knows or guesses the address can open the same inbox. Never let anything personal, financial or sensitive arrive there.
You don't know who runs the inbox. "Temp Gmail" sites in particular give you an address on an account they control, and there's no way to check who owns it or who else can read it.
Many sites block them. Lots of sign-up forms keep lists of disposable email domains and refuse them.
They're no shield for important accounts. Use your real address for your bank, doctor, employer, travel bookings and anything with legal or financial weight.

A better middle ground: forwarding aliases

If you want a random address that still reaches you and lasts as long as you need, a forwarding alias service is usually the better choice. Apple's Hide My Email, part of iCloud+, creates unique random addresses that forward to your inbox, and you can reply without revealing your real address; you can create as many as you need. Mozilla's Firefox Relay does something similar with what it calls email masks. Mozilla itself advises against using masks for very important mail or when you need your identity verified, and notes some sites won't accept them. For a broader look at aliases, see our guide to email aliases.

What Gmail aliases and temp emails won't do

It helps to be clear about the limits, because a lot of "Gmail generator" content oversells them:

They don't create new accounts. Every dot and plus version is still you, with one inbox, one password and one storage quota.
They aren't anonymous. Your real address is visible inside a dotted or plus alias. When you reply, Gmail sends from your main address unless you've added another address you own under Send mail as.
They don't get around sign-up limits. Using alias variations or throwaway inboxes to claim the same free trial, bonus or vote again, or to get back onto a service that banned you, usually breaks that service's terms, and sites can spot it easily by stripping dots and plus tags. Google's own Gmail Program Policies forbid creating or using multiple accounts to get around restrictions.
They don't secure your email. An alias decides where mail arrives. It doesn't encrypt anything or stop phishing at that address.

When you need a real second Gmail address

If what you actually want is a separate inbox, for a side business, a shared household address or keeping work and personal mail apart, a second Google account is the honest answer. It's free, it's allowed, and it doesn't vanish after ten minutes. Google also lets you create a Google Account with an existing non-Gmail address. Our step-by-step guide covers how to create a new Google account.

Frequently asked questions

Is the Gmail dot trick real?

Yes. Google's help page "Dots don't matter in Gmail addresses" confirms that every dotted version of a @gmail.com address belongs to the same person and delivers to the same inbox. It doesn't apply to work or school addresses, where dots change the address.

Can I create a temporary Gmail account?

Not really. A Gmail generator makes variations of the account you already have, and "temp Gmail" sites give you access to an inbox someone else controls. If you need a short-lived address, use a disposable email service for throwaway sign-ups only, or a forwarding alias you can switch off. If you need a separate inbox, create a second Google account.

How do I get a temp Gmail without dots?

Use a plus address: add + and a word after your username, such as yourname+temp@gmail.com. It reaches your normal inbox, and you can create a Gmail filter that deletes everything sent to it once you're done.

Are Gmail generators safe?

Alias generators are harmless in themselves, since they only rearrange your own address, but you're typing that address into a third-party site, and you can make the same aliases by hand. Temp Gmail sites are riskier: you can't tell who controls the inbox or who else can read it, so never use them for anything personal or important.

What is a throwaway email?

A throwaway (or use and throw) email is a temporary address from a disposable email service that you use once, typically to receive a confirmation link, and then abandon. It expires after minutes to days, so any account tied to it can't be recovered later.

Can I send email from a Gmail alias?

Mail sent to a dot or plus alias arrives in your normal inbox, and replies go out from your main address by default. To send as a different address you own, Gmail has a Send mail as setting under Settings > See all settings > Accounts and import.
