How to Manage Multiple Inboxes and Accounts in Gmail

My email inbox acts as my to-do list. Some of my emails are threads around a pending project, some are about a relationship.

I'm working with a new writer, and each one requires a certain response and prioritization in my day.

That's where Gmail's "Multiple Inboxes" can help.

Gmail Multiple Inboxes

Multiple Inboxes are mini inboxes Google offers within your primary inbox. Organize your inbox into sections based on the email type, topic, or personal preference. It's worth noting you can't implement Multiple Inboxes if you're using Gmail Promotions, Social, Updates, or Forums tabs.

First, let's define some terms:

Primary Inbox: This is the main Gmail inbox most users currently have. It stores all your email as it comes in and only leaves this section when you archive an email or move it to another folder.

Multiple Inboxes: These are the new mini inboxes we are creating alongside your primary inbox to organize your inbox into multiple sections based on the email type. They can only be implemented for accounts that do not use Gmail's Promotions/etc tabs.

Interested in multiple inboxes? Below are the seven steps I took to organize and implement mine.

As a result, I'm saving hours of time in my daily email routine for lead generation and appointment setting — and you can too.

1. Navigate to your Gmail settings.

Simply click the gear icon at the top right of your primary Gmail inbox. Under the drop-down that appears, select "Settings."

Step 1

2. In the top navigation that appears, click "Advanced."

Step 2

3. Scroll down to "Multiple Inboxes," and select "Enable."

Be sure to click "Save Changes," after which Gmail will automatically re-direct you back to your inbox. But we're not done just yet ...


4. Create labels for each email type you'd like to bucket.

In the left-side panel of your inbox, scroll down and click "More", "Create new label," you can create the various groups you'd like to bucket your different email types into. Enter your label name and click "Create."

Step 4

I enjoy organizing my inboxes based on the priority of the email. Some of my emails need a response, even if I can't get to them right away. Others are to-do list items I simply can't forget. The remaining emails end up being items I can store in a backlog to return to.

- Tip -

To be extra organized in my inbox, I color-code each label. When clicking the little downwards arrow next to the label in the left-hand panel, I simply select "Label color," helping me visually represent my multiple inboxes.

5. With your labels created, navigate back to "Settings."

Navigate to and click the gear icon, "Settings", and then click "Multiple Inboxes" in the top navigation.

Step 5

6. Now, set the labels you'd like to appear in your inboxes.

Under "Current searches for the multiple inboxes," I input the additional inboxes I'd like in my inbox. These correspond with the labels I mentioned in step four. In order to properly display these inboxes, be sure to use the format "is:label-name." Your queries will need to be lower-case and use dashes instead of spaces.

Step 6

You can also select the max number of emails that can appear in each inbox at a time under "Maximum page size". I also opt to have my new multiples inboxes appear to the right of my main inbox (as shown in the visual in step seven).

7. Click "Save Changes" to head back to your organized inbox.

Voila! Your new inbox should now look something like the one below.

Step 7 - 1

If the multiple inbox panes don't appear, navigate to the gear icon, "Settings", "Inbox", and make sure "Primary" is the only selected option in the "Categories" section.

Step 7 - 2

Next, let's take a look at the steps to use one inbox for multiple Gmail accounts.

Multiple Gmail Accounts One Inbox

  • Navigate to your "Accounts" settings.
  • Add the secondary Gmail account to the primary Gmail account.
  • Click the "Send Verification" button.
  • Navigate to the secondary account's "Forwarding and POP/IMAP" settings.
  • Add the primary account's email address to the "Forwarding" settings.
  • Add the primary account's email address to the "Forwarding" settings.
  • Confirm the forwarding email address.

Select a forwarding option.

If you have multiple Gmail accounts, you can pick a primary inbox to send from and merge your secondary accounts to the primary one. Below, we'll take a look at the steps to set this up.

1. Navigate to your "Accounts" settings.

If there's one Gmail account you check more frequently than others, use this as your primary inbox. Navigate to the gear icon, click "Settings", and then click "Accounts" in the top navigation.

2. Add the secondary Gmail account to the primary Gmail account.

In the "Send mail as:" section, click on the "Add another email" link.

M1 - Step 2

Then, type your full name and the secondary email address you'd like to add. You can choose to either check or uncheck the box to the left of "Treat as an alias" is checked" (check out this Google article for more information).

M1 - Step 2 - 2

Checking the box means that emails sent to the secondary email address appear in the primary Gmail account's inbox, which is the goal we're trying to achieve in this example. Once you've checked the box, then click the "Next Step >>" button.

Enter the verification code.

The next step is to forward the emails from the secondary account to the primary account. Navigate to the secondary account's "Settings" and click the "Forwarding and POP/IMAP" tab in the top navigation.

M1 - Step 5

6. Add the primary account's email address to the "Forwarding" settings.

In the "Forwarding" section, click the "Add a forwarding address button". This is where you'll enter the email address for the primary account. Click the "Next" button and then the "Confirm" button. A pop-up window will appear, you'll click the "Proceed" button, and a confirmation email will be sent to your primary Gmail account.

M1 - Step 6

7. Confirm the forwarding email address.

Copy the confirmation code from the email and paste it into the confirmation code field in the "Forwarding" settings in your secondary Gmail account. Click the "Verify" button.

M1 - Step 7

8. Select a forwarding option.

Finally, click the checkbox to "Forward a copy of incoming mail to … " and select a forwarding option from the drop-down.

M1 - Step 8

Once an option is selected, emails from your secondary Gmail account will be forwarded to your primary Gmail account. Having all of your emails in one place will save you time and make it easier to manage multiple inboxes.
