Gmail Aliases: How to Create and Use Them

A Gmail alias lets you hand out a different version of your email address without opening a second account — useful for sorting your inbox, signing up for newsletters, and spotting which company leaked your address to spammers. Gmail has three built-in ways to do this, and they’re all free. This guide walks through each one step by step, shows where they quietly fall short, and explains when a true forwarding alias is the better tool. By the end you’ll know exactly how to create a Gmail alias and, just as importantly, when not to rely on one.

What is a Gmail alias

A Gmail alias is an alternative form of your existing Gmail address that still delivers to the same inbox. You don’t create a new mailbox, a new password, or a new login — every message sent to the alias lands in the account you already use. The appeal is simple: you can give each website, store, or contact a slightly different address, then filter, label, or trace mail based on which alias received it.

Gmail supports three native techniques, and it helps to name them clearly before we set any of them up:

• Plus-addressing — append +anything to your username, e.g. yourname+shopping@gmail.com. This is the classic alias trick and the one most people mean by the term.
• Dot variations — Gmail ignores dots in the username, so your.name@gmail.com and yourname@gmail.com are the same mailbox. Each dotted spelling is effectively another alias.
• Send Mail As — link a second address you own so Gmail can send and receive from it. With Google Workspace, an admin can attach true alias addresses to your account.

The first two are built on an old email standard called sub-addressing, documented in RFC 5233. Plus-addressing isn’t unique to Google — many providers including Outlook, Fastmail, and ProtonMail support it — but Gmail is where most people first meet the concept. Each method has a different setup, a different use case, and a different failure mode, which is why it’s worth understanding all three rather than reaching for the first one you find.

Because every one of these resolves to the same mailbox, there’s nothing extra to manage: no second password, no separate storage quota, no app to switch between. Google has supported the underlying behavior for well over a decade, so it’s stable and works identically on the web, on iPhone, and on Android. That low overhead is exactly why the technique caught on — you get the sorting and tracing benefits of multiple addresses while still living in one inbox. The trade-off, which we’ll return to, is that “convenient and free” and “private” are not the same thing, and the gap between them is where most people get caught out.

Why use a Gmail alias in 2026

The reason a Gmail alias is still popular years after the feature shipped is that the problems it solves have only gotten worse. The average person now has well over a hundred online accounts, and every one of them is a place your address can leak, get sold, or end up in a breach. It gives you three concrete advantages:

• Automatic inbox organization. Because the alias is visible in the “To” field, you can build Gmail filters that label or archive mail based on it — yourname+receipts@gmail.com straight into a Receipts label, no manual sorting.
• Leak tracing. Give each company a unique alias and you’ll know exactly who is responsible when spam or a phishing attempt arrives. If yourname+acmestore@gmail.com suddenly gets junk, Acme Store either sold your data or was breached.
• Lower commitment than a new account. You get separation between contexts — work signups, shopping, forums — without juggling multiple inboxes and passwords.

Those benefits are real, and for low-stakes sorting a plus alias is genuinely handy. The catch is that Gmail’s built-in aliases were designed for organization, not privacy — and as we’ll see, the moment your goal shifts from “tidy my inbox” to “hide my real address and shut off spam,” the native methods start to crack. Understanding both sides is the difference between an alias that helps you and one that quietly exposes you.

How to create a Gmail alias with plus-addressing

Plus-addressing is the fastest Gmail alias to create because there’s nothing to set up — it already works on every Gmail and Google Workspace account. To make one, take your normal address and insert a plus sign followed by any word or number before the @ symbol:

1. Start with your real address: yourname@gmail.com.
2. Add + and a label of your choice: yourname+newsletter@gmail.com.
3. Use that address anywhere you’d normally type your email — a signup form, a checkout page, a contact field.
4. Every message sent to it arrives in your normal inbox, with the full alias preserved in the “To” header.

To make the alias actually save you time, pair it with a filter. In Gmail, open Settings → Filters and Blocked Addresses → Create a new filter, type the full alias in the “To” field, click Create filter, then choose an action such as applying a label or skipping the inbox. Now every message to yourname+newsletter@gmail.com is sorted automatically. Google documents the underlying behavior in its Gmail help center. You can create an unlimited number of these on the fly — no two need to be registered in advance.

How to create a Gmail alias with dots

The second native method is the dot trick. Gmail simply ignores periods in the username portion of an address, which means every way you can sprinkle dots into your name resolves to the same mailbox. This gives you a quieter alias — one without a visible +tag that some forms reject.

1. Take yourname@gmail.com.
2. Insert one or more dots: your.name@gmail.com, y.ourname@gmail.com, or your.name.@gmail.com all work.
3. Mail to any spelling lands in your single inbox.
4. Filter on the exact dotted address the same way you would a plus alias.

Dot variations look more like a “normal” address than a plus alias, so they slip past forms that block the plus sign. The downside is that you have far fewer of them — there are only so many sensible places to put dots in your name — and they’re easy for anyone to guess. A dotted alias is best treated as a lightweight sorting tool, not a privacy measure.

How to add a Gmail alias with Send Mail As

The third method is the most powerful and the most involved. “Send Mail As” lets Gmail send and reply from a different address — so you can send from a separate identity, while still working from one inbox. There are two routes, depending on the kind of address you want.

Route 1 — a Google Workspace alias. If you’re on Google Workspace (a custom-domain Google account), an administrator can attach genuine alias addresses to your mailbox from the Admin console. Google lets admins add up to 30 email aliases per user. Once added, the alias receives mail in your inbox automatically, and you can select it in the “From” dropdown when composing.

Route 2 — link an address you control. For a free @gmail.com account, you connect an external address you already own, following Google’s Send mail as instructions:

1. Open Settings → See all settings → Accounts and Import.
2. Under Send mail as, click Add another email address.
3. Enter the alias address and its display name, then follow the SMTP and verification steps.
4. Click the confirmation link Google sends to that address.
5. The alias now appears in the “From” menu, letting you send as it from inside Gmail.

Send Mail As is the only native option that lets you both send and receive under a separate identity — but it depends on you already owning or controlling that address. For most people that means paying for Google Workspace or wiring up a third-party mailbox, which is exactly the friction a dedicated alias service removes.

How to filter and label a Gmail alias

Creating the address is only half the job. The real payoff arrives when Gmail sorts that mail for you automatically, before it ever clutters your main view. Because the alias sits visibly in the “To” field, the filter engine can act on it — and setting that up takes about a minute.

1. Open Settings → See all settings → Filters and Blocked Addresses and click Create a new filter.
2. In the To field, type the full address — for example yourname+receipts@gmail.com — and click Create filter.
3. Pick the actions you want: Apply the label (create one like “Receipts”), Skip the Inbox to archive on arrival, Mark as read, Star it, or even Forward it to someone else.
4. Tick Also apply filter to matching conversations so existing mail gets sorted too, then save.

From then on, every message to that address is filed the instant it lands. A few patterns are worth knowing once the basics click:

• Color-code your labels. Hover a label in the sidebar, open the three-dot menu, and assign a color. Shopping in amber, newsletters in grey, finance in green — your inbox becomes scannable at a glance.
• Nest labels for structure. Create child labels such as Shopping/Receipts and Shopping/Shipping so related mail groups together under one parent.
• Search instead of scroll. Type to:yourname+receipts@gmail.com into the Gmail search bar to pull up everything that address has ever received, even items you archived.
• Quarantine a noisy address. If one of your addresses starts attracting junk, edit its filter to Delete it and the mail never reaches you — a crude off switch, but the closest the native methods get to one.

One practical note for phone users: you can’t build filters inside the Gmail mobile app, only on the desktop site. The good news is that any rule you create on desktop syncs to every device automatically, so mail to your tagged addresses sorts itself correctly on iPhone and Android too. Set the rules up once on a computer and they follow you everywhere.

Gmail alias methods compared

Each method trades off setup effort against how much it actually protects you. The table below lines them up against a dedicated forwarding alias so you can see where the native tools stop and where a purpose-built service takes over.

The pattern is clear: Gmail’s built-in aliases win on convenience and lose on privacy. They never hide the address underneath, and none of them give you a way to switch a single alias off when it starts attracting spam. That limitation isn’t a bug — it’s a consequence of how the methods work, which is worth looking at directly.

The limits of Gmail’s built-in aliases

A Gmail alias built on plus-addressing or dots has the same structural weakness: your real address is sitting in plain sight inside it. Anyone who receives yourname+acme@gmail.com can delete the +acme and the dots and arrive at yourname@gmail.com in two seconds. That single fact drives every one of the practical problems below.

• Spammers strip the tag. Any list broker or scraper that knows the trick removes the +tag automatically, so your “unique” alias collapses back to your real address and the spam follows you everywhere.
• Many forms reject the plus sign. Plenty of checkout and signup fields refuse + as an invalid character, so the plus alias you wanted to use simply won’t be accepted.
• There’s no off switch. When a plus or dot alias starts getting junk, you can filter it — but the mail still arrives, still counts against your storage, and still ties back to your real address. You can’t revoke it.
• It reveals you’re a Gmail user. The @gmail.com domain is right there, which is information you may not want to hand to every random website.
• No real anonymity. Because the base address is recoverable, a Gmail alias offers organization, not privacy. For anything sensitive, it’s the wrong tool.

None of this makes plus-addressing useless — for sorting receipts and newsletters it’s perfectly fine. But if you adopted a Gmail alias hoping to keep your real address private or to kill spam at the source, the method can’t deliver that. For those goals you need an alias that never contains your real address in the first place. We cover the broader trade-off in our deep dive on email aliases versus Gmail plus-addressing.

When to use a real email alias instead

A real email alias — sometimes called a masked or forwarding alias — is a standalone address that forwards to your inbox without ever exposing it. Unlike a Gmail alias, the address it forwards to is hidden, so there’s nothing to strip back to. This is the model behind EmailAlias.io and similar privacy tools, and it closes every gap left by Gmail’s native methods.

Here’s what a dedicated alias does that a Gmail alias can’t:

• Your real inbox stays secret. The forwarding address contains no trace of your underlying account, so it can’t be reverse-engineered the way a plus or dot Gmail alias can.
• One-click kill switch. If an alias starts getting spam, disable it and the flow stops dead — without touching any of your other addresses. That’s the per-alias off switch the native methods lack.
• Built-in leak detection. Because every site gets its own alias, a privacy service can flag the exact moment one of your addresses turns up in spam or a breach, so you know who exposed you.
• Send and reply privately. Good alias services let you reply from the alias, so the recipient still never sees your real inbox — something a plus Gmail alias can’t do on its own.
• Works on every form. Aliases look like ordinary addresses, so they sail through the checkout fields that reject the plus sign.

EmailAlias.io gives you 10 aliases free, with no card required, and a paid plan at $4/month for those who want unlimited aliases, custom domains, and real-time leak alerts. You can spin up an address from the dashboard or the email alias generator and start using it in seconds — and because these aliases are permanent forwarding addresses, not throwaways, they keep working for as long as you want them. If your goal is privacy and spam control rather than simple sorting, that’s the upgrade path from a Gmail alias. You can read exactly how the forwarding works on our security page, and why permanent aliases beat temporary inboxes on our not-disposable-email explainer.

Common use cases for a Gmail alias

Whichever method you choose, the practical uses for a Gmail alias are broadly the same. Here are the situations where readers reach for one most often, and the approach that fits each best:

• Newsletters and marketing. A plus or dot Gmail alias is plenty for sorting promotional mail you don’t mind receiving — filter it into a Newsletters label and keep your main inbox clean.
• Online shopping. Give each store its own address so you can trace leaks. For shops you trust, a Gmail alias works; for one-off or sketchy retailers, a disposable-resistant forwarding alias you can disable later is safer.
• Free trials and downloads. When you just need to receive one confirmation, any Gmail alias does the job — though a dedicated alias you can switch off afterward avoids the follow-up marketing entirely. See our guide on how to stop email spam for the full workflow.
• Public posts and forums. Anywhere an address might be scraped, skip the Gmail alias — the recoverable base address makes it a poor shield. A masked anonymous forwarding alias is the right call.
• Separating work and personal signups. Filters keyed on a Gmail alias keep contexts apart without a second account.

The rule of thumb is straightforward: use a Gmail alias for organizing mail you’re happy to receive, and a dedicated forwarding alias for anything where you’d rather keep your real address — and your ability to cut off the sender — firmly in your own hands.

Final thoughts

A Gmail alias is one of the most useful free features hiding in plain sight inside your account. Plus-addressing and dot variations cost nothing and take seconds to create, and Send Mail As gives you a genuine alternate identity if you’re willing to set it up. For tidying your inbox, tagging signups, and building smart filters, they’re hard to beat.

Just be honest about what a Gmail alias is and isn’t. It’s an organization tool, not a privacy shield: every native method leaves your real address recoverable and gives you no way to switch a single alias off. The moment your priority becomes hiding your inbox, stopping spam at the source, or knowing exactly who leaked your data, you’ve outgrown the built-in options — and a dedicated forwarding alias picks up precisely where Gmail’s stop. Start with 10 free aliases on EmailAlias.io and keep the plus trick for sorting your receipts.
