Gmail Alias Generator
Free Gmail alias generator. Create + tag aliases and dot variations of your Gmail address to filter spam, track signups, and spot who leaked it.
Enter the username part only. Everything you generate below delivers to this one inbox.
Add a +tag to your address. Gmail ignores everything after the +, so all mail still reaches you — but you can filter on the tag or spot who leaked your address.
Your address never leaves your device — every alias is generated locally in your browser.
Aliases sort the mail at the door. Something has to sort what got in.
NeatMail labels it, auto-archives the noise, and bulk-unsubscribes from the lists your aliases collected — while tracking every promise buried in the mail that's actually worth reading.
About the Gmail Alias Generator
A Gmail alias generator instantly turns one Gmail address into hundreds of working variations that all land in the same inbox — no new accounts, no forwarding, no setup. It relies on two features Google has supported for years: plus-tags (yourname+shopping@gmail.com) and dot-insensitivity (your.name@gmail.com). Gmail ignores everything after the + and every dot before the @, so each variation still reaches you normally. A single 8-letter username already has 128 valid dot spellings — 2 to the power of (length − 1) — plus unlimited +tags, and this tool generates and normalizes them for you entirely in your browser. Nothing is uploaded or stored.
How to use the Gmail Alias Generator
- 1
Enter your Gmail username
Type the part before @gmail.com. Dots are optional — the generator normalizes them so you start from a clean base address.
- 2
Choose an alias type
Pick Smart Aliases (+ tags) to label and filter signups, or Dot Variations for forms that reject the + character.
- 3
Add tags or presets
Tap a preset like Newsletter or Shopping, or add your own tag such as a store, app, or website name.
- 4
Copy and use it anywhere
Copy any alias and paste it wherever you sign up. Mail still lands in your normal Gmail inbox, tagged so you can filter it.
How many aliases can one Gmail address make?
Plus-tags are unlimited — you can invent a new +tag for every service you ever sign up for. Dot variations are finite but grow fast: a username with n letters has 2^(n−1) valid spellings, because Gmail ignores a dot in each of the n−1 gaps between letters. That is why `johndoe` (7 letters) produces 64 addresses, while a longer name runs into the thousands.
| Username length | Dot variations (2ⁿ⁻¹) | Example base |
|---|---|---|
| 5 letters | 16 | j.o.hns |
| 7 letters (johndoe) | 64 | john.doe |
| 10 letters | 512 | — |
| 12 letters | 2,048 | — |
| 15 letters | 16,384 | — |
This generator orders dot variations from fewest dots to most, so the most natural-looking addresses appear first, and lets you load more on demand instead of dumping thousands at once.
+ tag or dot variation: which alias should you use?
They are not interchangeable. A + tag carries a readable label you can filter and track on; a dot variation is only a different spelling of the same name with no label. Pick by what you are trying to do:
| What you want to do | Best choice | Why |
|---|---|---|
| Filter or auto-label a signup | + tag | The tag (`+shopping`) is visible in the message, so a Gmail filter can catch it. |
| Find out who leaked or sold your address | + tag | If `+shopping` suddenly gets spam, that one vendor is the source. |
| Use a form that rejects the + character | Dot variation | Dots are always accepted and reach the same inbox — the + fallback. |
| Truly hide your identity from a sender | Neither | Both normalize back to one address; a determined sender can strip them. |
Attribution vs. blocking: what aliases really do
The one thing to internalize: a +tag tells you who leaked your address, but it doesn't stop them by itself — that's the difference most alias guides skip. Here's exactly where each trick ends, and where it doesn't:
- + tags are strippable. They are excellent for *attribution* — knowing who leaked your address — but weak as a *block*: a motivated sender can delete `+shopping` and reach your base inbox. To actually stop them, filter that alias straight to Trash.
- Dots don't create separate identities. To Gmail, `john.doe` and `johndoe` are the same account, so any site that dedupes by normalized address will reject a dot variation as a duplicate signup.
- The dot trick is consumer-Gmail only. It works on @gmail.com and @googlemail.com, but Google Workspace custom domains may have it disabled at the admin level — test one message first.
- Some forms silently normalize the +. A few signup systems strip everything after the + before saving, so the tag never arrives. For anything important, send yourself a test first.
Turn an alias into your block button (filter recipe)
A +tag by itself only *labels* mail — the actual block comes from pairing it with a filter, and that combination is the one thing no other alias trick gives you: a per-signup off switch. In Gmail, open Settings → Filters and Blocked Addresses → Create a new filter, then:
- In the To field, enter your alias, e.g. `yourname+shopping@gmail.com`.
- Pick an action: Skip the Inbox (archive), Apply a label like “Shopping”, or Delete it.
- The block: if that alias later fills with spam, edit the filter to Delete it — you've cut off the exact company that leaked you, without ever changing your real address.

Frequently asked questions
- Are Gmail aliases against Google's terms of service?
- No. Plus-addressing and dot-insensitivity are official, documented Gmail features meant for exactly this kind of organizing and filtering, and every alias points back to your own real inbox. That is completely different from creating multiple fake or throwaway Gmail accounts, which does violate Google's terms.
- Do plus and dot aliases work with a Google Workspace (custom domain) account?
- Plus-addressing (you+tag@yourdomain.com) generally works on Workspace. Dot-insensitivity is a consumer-Gmail behavior and is not guaranteed on custom domains — an administrator can enable or disable how the address is normalized. If you're on a work domain, send yourself one test message before relying on a dot variation.
- If I use lots of aliases, how do I know which one an email came to?
- You don't have to remember — every message still arrives in your one inbox, and the exact alias is shown in the email's "to" header. Open a message, click the recipient details (or use our email header parser), and you'll see whether it reached yourname+shopping or a dot variation, so you know instantly which signup it came from.
- Can I send email from an alias, or only receive?
- Aliases are for receiving. You can't sign in with one, and by default Gmail sends replies from your real address, not the +tag or dot spelling the message came to. That's fine for their purpose — sorting, filtering, and tracking incoming mail. If you specifically need to send as a variation, that's a separate Gmail "Send mail as" setup, not something the alias itself does.
- Do these aliases work with Outlook, Yahoo, or iCloud?
- The dot trick is Gmail-only — Outlook, Yahoo, and iCloud treat every dot as a distinct character, so your.name and yourname are different mailboxes there. Plus-addressing is more portable: Outlook and iCloud support it too, though some providers use their own alias systems instead. And yes, both still work in 2026 — they're official, documented Gmail features, not a loophole that gets patched.
- Can websites detect or block Gmail aliases?
- A few signup forms try. Some reject the + character outright (switch to a dot variation), and a handful normalize the address — stripping the +tag or the dots — so a "new" alias is seen as your existing account. Most sites accept them fine. If one refuses, the dot variations are the quiet fallback, since they look like an ordinary address with no special characters.
- Is this Gmail alias generator free and private?
- Yes. It's completely free, needs no signup, and runs entirely in your browser. Your Gmail username is never uploaded or stored — every alias is generated locally on your device.
