Google Workspace Email Alias: The Basics

In Google Workspace, an email alias is an additional email address for an existing user account. Emails sent to the alias are automatically delivered to the user's primary Gmail inbox — no separate login, no separate storage.

For example, if your primary address is [email protected], you could add aliases like [email protected] or [email protected] — both would deliver to John's inbox.

Two Types of Email Aliases in Google Workspace

Type 1: User Aliases (Admin Console)

Set by the Google Workspace admin for individual users. Each user can have up to 30 aliases. These are permanent, domain-verified aliases managed centrally.

Type 2: Google Groups as Shared Aliases

A Google Group (like [email protected]) can receive emails and distribute them to multiple members. This is how Google Workspace handles "shared inbox" scenarios — though it lacks many features of a true shared inbox tool.

Step-by-Step: How to Set Up an Email Alias in Google Workspace

Step 1: Sign In to Admin Console

Go to admin.google.com and sign in with your Google Workspace admin account.

Step 2: Navigate to the User

Click Directory > Users, then select the user you want to add an alias for.

Step 3: Add Alternate Emails

1. Click on the user's name to open their profile
2. Click User information to expand it
3. Click Alternate emails
4. Click Add Alternate Email
5. Type the alias name and select the domain from the dropdown
6. Click Save

Aliases are active within a few minutes. The user can immediately receive mail at the new address.

Google Workspace Email Alias Limits: What You Need to Know

Limit Type	Limit	Notes
Aliases per user	30	Includes all domains in your Workspace
Domain aliases	20 per account	Each domain alias adds aliases for all users automatically
Alias availability after creation	~24 hours	For sending; receiving is faster
Can user send from alias?	Yes (via Gmail settings)	User must manually add in Gmail > Settings > Accounts
Can alias be shared across users?	No (use Groups)	Aliases belong to one user only

How to Let Users Send Email From Their Alias

By default, Workspace aliases only receive. To send from an alias in Gmail:

1. Open Gmail > Settings (⚙️) > See all settings
2. Go to the Accounts and Import tab
3. Under "Send mail as", click Add another email address
4. Enter the alias address and follow the verification steps
5. Once verified, you can select the alias as the "From" address when composing

⚠️ Note: This only works for user-level aliases managed by the admin. It won't work for Google Groups email addresses.

Google Workspace Alias Limitations vs. GridInbox

Google Workspace aliases work well for basic scenarios, but they fall short for:

• Shared team aliases: Multiple people can't share a single alias in Workspace (you'd need a Group, which has its own limitations)
• More than 30 aliases per user: Power users (especially developers, agencies, e-commerce teams) hit this ceiling
• API-driven alias creation: Google's Admin SDK is complex and requires OAuth2 service account setup
• OTP / automated email reading: Gmail doesn't expose an API designed for reading OTP codes programmatically
• Role-based access (RBAC): Workspace can't grant team member A access to alias X but not alias Y

Max aliases per user	30	Unlimited (paid)
Shared team aliases	Via Groups only	✅ Native shared inbox
RBAC per alias	❌	✅ Yes
REST API for alias mgmt	Complex Admin SDK	✅ Simple REST API

When to Use GridInbox Instead of Google Workspace Aliases

Choose GridInbox when you need:

• More than 30 aliases on a domain (agencies, developers, e-commerce stores)
• A team to share access to a single alias (e.g., [email protected] handled by 3 agents)
• Programmatic alias creation via REST API (QA automation, CI/CD pipelines)
• OTP extraction without manual Gmail checking
• A free plan to start without committing to per-user Workspace fees

GridInbox can work alongside Google Workspace — you keep your Workspace accounts for internal email, and use GridInbox for your customer-facing aliases and shared inboxes.

Setting Up GridInbox as a Google Workspace Alias Alternative

1. Sign up at mail.gridinbox.com/register (free)
2. Add your domain — update MX records to point to GridInbox (keep a secondary MX for Workspace to maintain internal delivery)
3. Create aliases — e.g., [email protected], [email protected]
4. Invite team members with specific alias permissions
5. Automate via REST API if needed

Google Workspace Email Alias: Common Questions

Can I delete a Google Workspace email alias?

Yes. In Admin Console, go to the user's profile > User information > Alternate emails, and remove the alias. It may take up to 24 hours to fully release.

What happens to emails sent to a deleted alias?

After deletion, emails sent to the old alias will bounce with a "user not found" error. Make sure to set up redirects or communicate address changes before removing aliases.

Can I set up a catch-all email in Google Workspace?

Yes. In Admin Console > Apps > Google Workspace > Gmail > Default routing, you can set up a catch-all that routes all unrecognized addresses to a specific mailbox. This is useful for receiving emails at any address on your domain.
