What is an email alias? A Gmail and Workspace guide

What is an email alias?

An email alias is an additional address connected to an existing inbox. In Google Workspace, an administrator assigns the alias to one user. Google delivers messages for the alias to that user's primary inbox, and the alias doesn't have its own login, inbox, Drive, or Calendar.

Gmail plus addresses, shared role addresses, and forwarding arrangements are also often called aliases, though people use each for a different purpose. You look professional to customers when your address uses your real name or a role at your own domain instead of a nickname or a free-mail address, and if you're still choosing one, there are examples of professional email addresses to start from.

Workspace alias, Gmail plus address, shared role address, or separate mailbox

Start with who will use the address. If only you will read the mail, keep everything in your existing Google account and choose either a Google Workspace alias or a Gmail plus address. An alias or plus address gives no shared access to several people who need to read, reply, or manage messages. Use a shared role address through Gmail delegation, a Google Group, or a shared mailbox instead.

How Google Workspace aliases work

An administrator can add up to 30 aliases to one user at no extra cost, according to Google Workspace Admin Help. These addresses all belong to that user's primary account. Google states that email aliases aren't private and that an alias can appear in another user's search results, so an alias keeps your primary address off a form or a public page without making the mail anonymous.

Mail sent to the alias arrives as soon as the administrator creates it, but sending from it takes another step. In Gmail, add the alias as a custom From address. Once you do, Gmail lists it in the From menu when you write a message. Gmail will stop supporting Send as for third-party addresses such as @yahoo.com and @outlook.com in January 2027. Google Workspace aliases and other Gmail addresses you own aren't affected.

How Gmail plus addresses and dots work

A plus address adds a visible tag between the username and the @ sign. The address cassy+news@solarmora.com, for example, reaches the same inbox as cassy@solarmora.com, as Google Workspace Learning Center explains. You can filter on the tagged address without asking an administrator to create it first.

This makes a different plus address useful for each service you sign up for. If mail sent to one of those tags later comes from somewhere else, the tag is a clue that the address may have been reused. It can't tell you which organization disclosed the address or whether anyone sold it, so check the messages and account activity before drawing a conclusion. If unwanted messages arrive, you can unsubscribe, block, and report them in Gmail.

The rule for dots depends on the domain. Dots are ignored in gmail.com usernames, so johnsmith@gmail.com and john.smith@gmail.com reach the same inbox. Dots do change addresses for Gmail used through work, school, or another organization, including custom Google Workspace domains.

Use Gmail delegation, Google Groups, or a shared mailbox for several people

A role address such as sales@, support@, or billing@ can be a user alias when one person handles the mail. Google's small-business example uses separate aliases for several functions managed by the same user.

Google Workspace Admin Help states, "Only one user can use an email alias." Google recommends Gmail delegation when several people need to use the address. Google Groups can distribute messages and control membership, while a dedicated shared mailbox gives the address its own message history and access settings.

When to use a separate account

Use a separate account if another person has to work from the address without seeing your primary inbox. A separate account is also appropriate if the address needs its own message history, administrator, Drive, Calendar, security settings, or recovery process.

You can run a side project on an alias while you handle the mail alone. Once you hire someone or need separate records and services, create a separate account and follow the email address change checklist.

Use a bulk email service for newsletters and campaigns

An alias or ordinary mailbox doesn't provide the sending infrastructure, reputation controls, or unsubscribe handling that campaigns need.

Google's email sender guidelines require SPF or DKIM for all senders to personal Gmail accounts. Senders who send more than 5,000 messages per day need SPF, DKIM, and DMARC. Marketing or subscribed messages at that volume also need one-click unsubscribe. Google advises senders to start with low volume and increase it gradually.
