How to Create a Free Email Alias (Gmail, Outlook, iCloud & More)

Every time you type your real email address into a sign-up form, you’re making a bet. You’re betting that company won’t get breached, won’t sell your info to data brokers, and won’t spam you into oblivion. Spoiler: you’ll lose that bet more often than you’d like. In 2024 alone, over 3,000 data breaches exposed billions of records — and email addresses were in nearly every single one.

An email alias gives you a way out. Instead of handing over your actual address, you create a separate address that forwards mail to your real inbox. If that alias gets compromised or annoying, you just turn it off. Your real email stays untouched. It’s like giving out a phone number that you can disconnect at any time — without changing your actual number.

The good news? You can create email aliases for free using Gmail, Outlook, iCloud, or a dedicated service like Alias Email. This guide walks you through every method, step by step, so you can pick the one that actually fits how you use email.

What Is an Email Alias (And Why Would You Want One?)

An email alias is a forwarding address. Mail sent to the alias lands in your real inbox, but the sender never sees your actual email address. Think of it as a mask for your inbox.

Why bother? A few reasons. You can give a unique alias to every service you sign up for, which means you’ll know exactly who leaked or sold your info when spam starts showing up. You can kill a compromised alias without disrupting everything else tied to your main address. And if you’re signing up for something sketchy — a free trial, a one-time download, a forum you’ll never visit again — an alias keeps your real inbox clean. For a deeper dive, check out our full explanation of what an email alias is and how it works.

Some people confuse aliases with email forwarding or temporary burner addresses. They’re related but not the same. An alias is a persistent address you control — you can keep it running forever or shut it off whenever you want. According to a Verizon DBIR report, over 80% of breaches involve stolen credentials or personal data — and your email address is usually the first piece to go.

The Gmail Plus (+) Trick — And Why It’s Not Enough

You’ve probably seen this tip floating around: just add a + sign and a tag to your Gmail address. So you+shopping@gmail.com and you+newsletters@gmail.com both deliver to you@gmail.com. It’s built into Gmail and requires zero setup.

Sounds great. Here’s the problem: it doesn’t actually hide your real email address. Anyone looking at you+shopping@gmail.com can see your real address is you@gmail.com. It takes about two seconds to strip the plus sign. Many websites do exactly that, either intentionally or because their form validation rejects the + character entirely.

The plus trick is useful for filtering and organizing mail. It is not useful for privacy. If a data broker gets you+randomsite@gmail.com, they have your real address. No work required. You can read more about how this works on Google’s support page, but understand that it was designed for organization, not protection.

That said, if you do rely on Gmail’s plus addressing and want to get more out of it, check out Trick Plus — a free tool that helps you manage and track your plus-sign aliases in one place. It won’t solve the privacy gap, but it makes the plus trick significantly more organized and useful for the things it’s actually good at, like filtering and spotting which services share your info.

How to Create an Email Alias in Gmail

Gmail doesn’t offer true alias creation in the way a dedicated service does, but you can add an alternate “send as” address. This lets you send and receive from a different address within your Gmail interface. Here’s how:

1. Open Gmail and click the gear icon in the top right, then See all settings.
2. Go to the Accounts and Import tab.
3. Under “Send mail as,” click “Add another email address.”
4. Enter the name you want recipients to see and the alias address. Uncheck “Treat as an alias” if you want to keep them separate.
5. Gmail will send a verification email to that address. Click the confirmation link or enter the code.
6. Once verified, you can choose to send from that address using the “From” dropdown when composing a new email.

The catch: you need to already own or have access to the other email address. Gmail doesn’t generate new addresses for you. This feature is really about consolidating existing accounts, not creating new aliases on the fly. For full details, see Google’s alias documentation.

If you’re on Google Workspace (the paid version), admins can create up to 30 aliases per user. But for regular free Gmail accounts, you’re limited to the plus trick and the send-as workaround above.

How to Create an Email Alias in Outlook

Microsoft makes it a bit easier. You can create actual alternate email addresses tied to your Outlook.com account — up to 10 aliases. Here’s the process:

1. Sign in to your Microsoft account page.
2. Click Your info at the top, then select “Manage how you sign in to Microsoft.”
3. Under Account aliases, click “Add email.”
4. Choose either to create a new Outlook.com address or add an existing email address as an alias.
5. If creating new, pick your address (e.g., yournewname@outlook.com) and confirm.
6. The alias is active immediately. Mail sent to it arrives in your main Outlook inbox.

This is better than Gmail’s approach because you’re getting a genuinely different address. But there are limits — 10 aliases total, and you can only add 3 per year (Microsoft recently tightened this). All aliases are also under the @outlook.com, @hotmail.com, or @live.com domains. No custom domains unless you’re paying for Microsoft 365. Full instructions are on Microsoft’s support page.

How to Create an Email Alias in iCloud

Apple offers two flavors of aliases. The first is traditional iCloud Mail aliases. The second is Hide My Email, which is the more interesting option. Let’s cover both.

iCloud Mail Aliases

1. Go to iCloud.com and open Mail.
2. Click the gear icon and select Preferences.
3. Go to the Accounts tab and click “Add an alias.”
4. Choose an alias name, a label, and a color for easy identification.
5. Click Done. Your alias is active.

You get a maximum of 3 aliases, and they all use the @icloud.com domain. Pretty limited.

Hide My Email (iCloud+)

If you pay for iCloud+ (starts at $0.99/month), Apple’s Hide My Email feature generates random addresses like random_string@privaterelay.appleid.com. These forward to your real iCloud inbox. You can create them directly in Safari, Mail, or the Settings app on iPhone.

This is genuinely useful for privacy. The generated addresses are random and can’t be reverse-engineered to find your real email. But you need to be in the Apple ecosystem, you need to pay for iCloud+, and you can’t use a custom domain. Check Apple’s support page for the latest details.

Why a Dedicated Email Alias Service Beats Built-in Options

The built-in options from Gmail, Outlook, and iCloud are fine for light use. But they all share the same fundamental problem: they’re tied to one provider. Your Gmail aliases only work with Gmail. Your iCloud aliases only work within Apple’s ecosystem. Switch providers and you’re starting from scratch.

A dedicated email alias service like Alias Email sits between the outside world and whatever inbox you already use. Gmail, Outlook, ProtonMail, Fastmail — doesn’t matter. The aliases forward to wherever you want. If you switch email providers next year, your aliases keep working. Nothing breaks.

There’s also the privacy angle. Built-in aliases from major providers are often easy to link back to your main account. A dedicated alias service generates completely independent addresses. There’s no visible connection between your alias and your real email. That matters when you care about keeping your real identity off the radar — especially given that the average data breach now costs $4.88 million, and exposed email addresses are often the starting point.

And then there’s control. Want to turn off an alias that’s getting spam? One click. Want to see which service sold your email? Give each one a unique alias and wait. The answer becomes obvious. It’s the same logic behind using a unique password for every account — compartmentalization is just good security hygiene.

How to Set Up a Free Email Alias with Alias Email

Setting up an alias with Alias Email takes about two minutes. No credit card needed.

1. Install the extension. Head to the download page and grab the browser extension for Chrome, Firefox, or Edge.
2. Create your account. Sign up with your real email address. This is the inbox where forwarded mail will land. Alias Email never shares or exposes this address.
3. Generate your first alias. Tap the create button and you’ll get a new, unique email address instantly. You can customize the alias name or let the email alias generator pick a random one for you. The free plan gives you up to 10 aliases — more than enough to get started.
4. Start using it. Copy the alias and paste it into whatever sign-up form, newsletter, or service you’re joining. Mail sent to that alias shows up in your real inbox. When you reply, the recipient sees the alias — not your real address.

That’s it. No DNS records to configure, no verification hoops to jump through. For a more detailed walkthrough with screenshots, see our full guide on creating an email alias.

Best Practices for Managing Your Aliases

Creating aliases is the easy part. Keeping them organized takes a little thought. Here are some practical tips:

• Use one alias per service. This is the single most useful habit. Give Netflix one alias, your bank another, that random forum a third. When spam appears, you’ll know exactly which service is responsible.
• Name your aliases descriptively. Something like shopping-amazon@ or newsletter-tech@ is much easier to manage than a random string. Future you will appreciate it.
• Disable aliases you no longer need. Cancelled a subscription? Stopped using a service? Turn off the alias. No more mail from them, ever. This is something you simply can’t do with your real address.
• Don’t use aliases for critical accounts. Your bank, your primary social media, your government tax portal — use your real email for things where account recovery matters most. Aliases are best for the hundreds of less-critical sign-ups.
• Combine aliases with strong passwords. An alias protects your email identity. A unique password protects your account. Use both together with a password generator and you’ve seriously reduced your attack surface.
• Review your aliases periodically. Every few months, look at what’s active. You’ll probably find aliases you forgot about that you can safely disable.

If you’re interested in using throwaway addresses for especially short-term needs, our burner email guide covers when disposable addresses make more sense than a permanent alias.

Key Takeaways

• An email alias forwards mail to your real inbox without exposing your actual address. It’s one of the simplest ways to protect your privacy online.
• Gmail’s plus (+) trick is not a real alias — your address is still visible and easily stripped. Tools like Trick Plus can help organize it, but they can’t fix the underlying privacy gap.
• Gmail, Outlook, and iCloud all offer some form of alias support, but with meaningful limits on quantity, customization, and provider lock-in.
• A dedicated email alias service gives you unlimited aliases, works with any email provider, and completely hides your real address.
• Best practice: use a unique alias for every service, name them clearly, and disable the ones you stop using.
• Combining aliases with unique passwords per account is one of the strongest moves you can make for your online security.
