Short Answer
To connect a Google account in BrandJet for outreach, start in BrandJet at brandjet.ai/accounts, click Add Account, and choose Google. For a Google Workspace mailbox, the important part is not just clicking the OAuth button. Your Google Workspace admin needs to trust the BrandJet OAuth app first, using the client ID shown inside BrandJet.
Once the admin approval is done, go back to BrandJet, press Connect Google Workspace, choose the right Google account, accept the OAuth permissions, and wait around 30 to 45 seconds for the account to finish connecting. I would not skip the admin approval step, because that is where most Google connection issues usually come from.
BrandJet also shows a note that the Gmail OAuth connection is lightweight and send-only for Google Workspace outreach. If you also need reply sync into the BrandJet inbox, connect the mailbox through SMTP/IMAP with an app password after the OAuth connection is handled.
Before You Start
The cleanest Google setup is done with two people involved: the person using BrandJet and the Google Workspace admin. The BrandJet user can start the connection, but the Workspace admin controls whether the BrandJet app is trusted for the organization.
| What You Need | Why It Matters |
|---|---|
| Access to BrandJet Accounts | This is where you open Add Account and choose Google. |
| Google Workspace Admin Access | The admin must approve BrandJet in API controls before OAuth works smoothly. |
| BrandJet OAuth Client ID | This is copied from the Google connector panel and used to find the BrandJet app in Google Admin. |
| The Correct Gmail User | The account you select in OAuth should be the mailbox you want to use for outreach. |
| All OAuth Permission Boxes Checked | BrandJet needs the requested permissions to send outreach through that Gmail account. |
Open The Google Connector In BrandJet
Go to brandjet.ai/accounts and click Add Account in the top right. BrandJet will open the Connect Your Account popup. Choose Google from the Email Accounts section.

After selecting Google, BrandJet shows the Google account connection panel. This panel gives you the OAuth client ID and explains the Google Workspace approval step.

Copy the OAuth client ID from BrandJet before moving to the Google Admin console. The admin will use that value to search for the BrandJet app. I would copy it directly from the BrandJet panel instead of typing it manually, because a single wrong character can make the admin search look broken.
Approve BrandJet In Google Workspace Admin
Ask your Google Workspace admin to open the Google Admin console. From there, go to Security, then Access and data control, then API controls. The goal is to manage which third-party apps can access user data.


Inside API controls, click Manage app access. This is the area where the admin can search for a third-party app and mark it as trusted.

Click Configure new app and search using the BrandJet client ID you copied from BrandJet. Searching by client ID is more reliable than searching by name, because it targets the exact OAuth app that BrandJet is asking you to authorize.

When BrandJet appears, select it. Then choose Trusted and apply the trust setting to the users who need Gmail outreach. If only a small outreach team needs this, the admin can limit access to those users instead of applying it too broadly.




Finish The Gmail OAuth Connection In BrandJet
Once BrandJet is trusted in Google Workspace Admin, go back to BrandJet and press Connect Google Workspace. This takes you into the normal Google OAuth flow.

Select the workspace account you want to connect. Use the exact inbox that should send outreach, not a personal account or another mailbox from the same browser session.

Google will show the BrandJet OAuth consent screen. Go through it normally and continue. When Google shows the permission list, check every permission box BrandJet asks for, then approve.


After approval, BrandJet may show a short loading state. Wait around 30 to 45 seconds. Do not refresh immediately unless it clearly stalls, because OAuth handshakes can take a moment to return and verify.

What To Check If Google Does Not Connect
If the account does not connect, I would check the admin approval first. Most failures happen because the OAuth app was not trusted, the trust setting was applied to the wrong users, or the wrong Google account was selected during OAuth.
-
The BrandJet client ID in Google Admin matches the client ID shown in BrandJet.
-
The app access level is set to Trusted, not blocked or limited incorrectly.
-
The user you are connecting is included in the applied access scope.
-
All Google permission boxes were checked before finishing OAuth.
-
Browser popups or redirects were not blocked during the OAuth flow.
If you need replies to sync into BrandJet as well, use the Existing Mailbox option with SMTP/IMAP and a Gmail app password. OAuth handles the Google connection for sending, while SMTP/IMAP is the practical path when you need mailbox-level reply access.
How To Know The Google Account Is Connected
Go back to the Accounts page and look for the connected Gmail account in your account list. The status should show as connected, and the account should be available when you build outreach that uses email. I would also send a small test outreach message before using it in a real campaign, just to confirm the account, permissions, and sender identity are all correct.
How To Use The Connected Google Account Carefully
After the Google account is connected, do a quick operational check before putting it into a live campaign. Confirm the sender name, the email address, the account group, and the sending limits inside BrandJet. A technical connection can be successful while the operational setup is still wrong. For example, the wrong mailbox might be connected, or the mailbox might be connected but assigned to the wrong campaign group.
The safest first test is small. Send a simple internal test message, then check whether it sends from the expected Gmail account. If reply sync matters for your workflow, reply to that test message and confirm the reply lands where you expect. This is especially important because BrandJet separates the Google Workspace OAuth connection from the SMTP/IMAP path used when you need deeper mailbox reply handling.
I would also avoid connecting several Google accounts in a rush without checking each one. When you connect many similar mailboxes, it is easy to approve OAuth for the wrong user or forget which mailbox was trusted by the admin. A clean naming convention in BrandJet makes later troubleshooting much easier.
Use Google OAuth And SMTP/IMAP For The Right Jobs
A useful way to think about this setup is that Google OAuth and SMTP/IMAP solve related but different problems. The Google Workspace OAuth flow proves that BrandJet is allowed to connect to the Gmail account through the approved Google app. SMTP/IMAP is the mailbox-level path you use when you need the account to send, receive, and track replies through standard mail protocols.
I would keep those two paths clear when troubleshooting. If OAuth fails, look at Google Admin approval, app trust, the selected user, and the consent screen. If reply sync or mailbox verification fails later, look at the SMTP/IMAP setup, app password, host, port, and security mode. Mixing those two problems together makes Google setup feel more confusing than it actually is.
Admin Approval Checklist For Google Workspace
Before you send the user back into BrandJet, the Workspace admin should confirm three things: the BrandJet client ID was searched correctly, the app is marked Trusted, and the trust rule applies to the exact user or group that needs outreach access. That last part matters because a trusted app setting can exist in Google Admin while still not applying to the mailbox you are trying to connect.
After the admin work is done, the BrandJet user should restart the OAuth flow from BrandJet instead of reusing an old half-open Google tab. A fresh flow reduces stale consent screens and makes it easier to confirm the correct Google account is selected.
