Zapmail lets you create mailboxes quickly—either one at a time or in bulk—and assign them to your domains. You can also choose between Google Workspace and Microsoft 365 before creating mailboxes.
This guide walks you through the complete process.
Before You Begin
Make sure:
Your domain is already added and active in Zapmail
You know how many mailboxes you want to create
For bulk creation, you have a CSV file ready (or use the sample template)
Step 1: Open the Mailboxes Section
Log in to your Zapmail dashboard
Go to the Mailboxes section
Step 2: Choose Your Mailbox Platform
Zapmail supports two mailbox platforms:
Google Workspace
Microsoft 365
Select your preferred platform by clicking the platform switch button in the top-right corner of the Mailboxes page.
💡 You must select the platform before assigning mailboxes.
Step 3: Assign Mailboxes
At the top of the Mailboxes page, you’ll see the number of unassigned seats available for the selected platform (Google Workspace or Microsoft 365).
These seats represent how many mailboxes you can still create.
Make sure you have enough unassigned seats before proceeding.
Click Assign Mailboxes to start creating mailboxes.
Step 4: Enter Mailbox Details
Fill in the required details for each mailbox you want to create:
Field | Description |
First Name | Display name for the mailbox |
Last Name | Display name for the mailbox |
Username | Email username (e.g., |
Domain | Select the domain the mailbox will be assigned to |
Profile Photo (Optional) | Upload an avatar if required |
➕ Need to add more mailboxes manually?
Click Add More Mailboxes to create multiple mailboxes in one go.
📥 Creating mailboxes in bulk?
Click Upload Bulk CSV to import multiple mailbox users at once.
You can download the Sample CSV file from the upload screen to ensure the correct format.

⚠️ Important: 24-Hour Mailbox Creation Rule
Once a Google Workspace or Microsoft 365 workspace is created for a domain, you have a 24-hour window to assign mailboxes.
After this window, no additional mailboxes can be added for a current billing cycle.
👉 Learn more in the 24-Hour Mailbox Creation Rule guide.
Microsoft 365 – Quick Note
The Microsoft workspace must be fully active before mailboxes can be assigned
If you skip mailbox creation initially:
Wait for workspace activation
Assign mailboxes within the 24-hour window
Zapmail does not allow adding mailboxes before the workspace is active
💡 Tip: Assign all required Microsoft mailboxes during initial setup to avoid delays.

Step 5: Assign Mailboxes & Place the Order
After entering all mailbox details:
Review the mailbox information
Click Assign Mailboxes to place the order
Zapmail will begin creating the mailboxes and provisioning them on the selected platform.
⚠️ Important: Once the mailbox order is placed, it cannot be reverted or deleted. Please review all details carefully before clicking Assign Mailboxes.
Step 6: Export Mailboxes to Your Outreach Platform
Once you click Assign Mailboxes, you’ll be redirected to the Export Mailboxes page.
From here, you can:
Select your outreach sending platform
Enter your platform credentials
Schedule the export in advance
Zapmail will automatically export your mailboxes as soon as they become active, so they’re ready to send without any manual steps.
💡 Why this helps: Pre-scheduling the export ensures your mailboxes connect to your outreach tool immediately after activation—saving time and avoiding delays.

In Progress | Mailbox creation is underway |
Creating Password | Mailbox is created; password and 2FA setup in progress (takes ~10–15 minutes) |
