Google Workspace Email Setup for Founders — Multi-Department Email on One Licence

Why Most Founders Overspend on Business Email

When setting up a new business, one of the first decisions is email infrastructure. You need a professional custom domain address, and most founders assume that each departmental address — hello@, accounts@, support@ — requires its own paid Google Workspace licence.

That assumption is incorrect. Google Workspace provides a mechanism called Google Groups that allows you to create an unlimited number of departmental addresses, all routing to a single paid user's inbox. The result is a corporate-grade email structure at the cost of one licence.

This guide documents the exact setup we recommended to one of our clients — KidsAI Pro, a global education technology company. Every step described below is drawn from a real production configuration that RxAI delivered as part of our Digital Foundation service.

Step 1: Choose Your Primary Account Identity

Your primary paid Google Workspace account should use your own name rather than a generic address. Addresses like admin@ or info@ are common targets for automated spam and lack a personal connection to clients.

This account serves as your login, your Super Admin identity, and your personal inbox. All departmental addresses will route into this same inbox using Groups.

Step 2: Create Departmental Addresses with Google Groups

Google Workspace allows up to 30 simple aliases per user, but Google Groups offer a more scalable approach. The key advantage: when you hire your first team member — an assistant, a bookkeeper, a developer — you can add them to the relevant group without sharing your personal login credentials.

To create a group, navigate to the Google Admin Console > Directory > Groups and create one group per departmental address. For KidsAI Pro, we created three:

• support@kidsaipro.com.au — Parent and user enquiries, technical help, and onboarding questions
• billing@kidsaipro.com.au — Subscription invoices, payments, and refund requests
• schools@kidsaipro.com.au — School and institutional partnership enquiries

Each group was configured with the founder (founder@kidsaipro.com.au) as the sole member and owner. Today, all three addresses deliver to one inbox. When the team grows, adding a new member to the appropriate group takes seconds.

Step 3: Fix the External Sender Permissions

This is the step that causes the most issues. By default, Google Groups restricts posting to internal organisation members only. If you skip this configuration, every customer who emails hello@yourdomain.com will receive a bounce-back error.

While adjusting external permissions, you should also configure the following for each group:

• Who can contact group owners: enable for External senders so system queries are not rejected.
• Who can view conversations: for collaborative groups like support@, allow members to view history. For sensitive groups like billing@, restrict conversation visibility to Owners only — this keeps financial correspondence private as your team grows.
• Who can join: set to "Only invited users" to prevent unauthorised additions.

Step 4: Configure "Send Mail As" for Outbound Replies

Receiving email to a group address is only half the setup. When a parent emails billing@kidsaipro.com.au and the founder replies, the outbound message will default to founder@kidsaipro.com.au as the sender. For brand consistency, you want the reply to appear as though it came from the departmental address.

To configure this:

1. Open Gmail > Settings > Accounts > Send mail as.
2. Click "Add another email address".
3. Enter the group address (e.g. billing@kidsaipro.com.au) and check "Treat as an alias".
4. Complete the verification step.

Once configured, you can select the appropriate sender address from the "From" dropdown when composing or replying. A parent asking about a subscription invoice will see billing@kidsaipro.com.au in their inbox — not the founder's personal address.

Step 5: Integrate with Your Website

With the email infrastructure in place, the final step is to update your website's contact pages and footer to reflect the new departmental addresses. Each address should be presented with a clear description of its purpose so that visitors and clients direct their enquiries to the correct department.

For KidsAI Pro, the contact page and site footer now display a structured directory:

• Support — support@kidsaipro.com.au — for parent and user enquiries
• Billing — billing@kidsaipro.com.au — for subscription invoices and payment questions
• Schools & Partnerships — schools@kidsaipro.com.au — for institutional and school partnership enquiries

This routing structure reduces the time spent manually forwarding emails and ensures that future team members receive only the correspondence relevant to their role.

What You Get at the End

After completing these five steps, you have a fully functional, multi-department corporate email infrastructure running on a single Google Workspace licence. The setup provides:

• A personal, founder-facing primary address that builds client trust.
• Multiple departmental addresses that all deliver to one inbox today.
• A scalable architecture that supports adding team members without credential sharing.
• Privacy controls that segregate sensitive financial correspondence from general access.
• Outbound reply capability from any departmental address for brand consistency.

The entire configuration takes approximately 30 minutes and costs nothing beyond the single Workspace licence you already have.
