📬Creating Mailboxes in Icemail: A Step-by-Step Tutorial

Setting up cold outreach mailboxes is a core part of managing your domains in Icemail. Whether you're adding a few mailboxes or uploading them in bulk for scale, this guide will walk you through both single and bulk creation workflows.

Before You Begin

Make sure:

• You have already connected your domain(s) to Icemail.

• You know whether you’re assigning Google Workspace, Microsoft 365, or Icemail-hosted mailboxes.

Creating a Single Mailbox in Icemail

Follow these steps to create and assign a single mailbox:

Step 1: Navigate to the Mailbox Dashboard

• Log in to your Icemail account

• From the left-hand menu, click on “Mailboxes.”

Step 2: Click on “Assign Mailbox”

• This button allows you to manually create and link a mailbox to a domain.

Step 3: Fill Out the Mailbox Details

• Enter the following:

  • Email address (e.g., jane@yourdomain.com)

  • Domain to associate the mailbox with

  • Password (if you’re creating mailboxes directly through Icemail)

  • Optional Tags for grouping (e.g., SDR1, Campaign A)

Note: Ensure all fields are accurate. Typos can cause login issues and domain conflicts.

Step 4: Click “Assign Mailbox”

• The mailbox will be created and linked to your selected domain.

Creating Multiple Mailboxes (Bulk Upload)

For scaling your campaigns, bulk mailbox creation is the most efficient option.

Step 1: Click on “Upload Bulk CSV”

• In the Mailboxes section, you’ll find the Bulk Upload option. Click it to begin.

Step 2: Download the Sample CSV

• Click “Download Sample CSV” to understand the exact structure required.

• The sample file includes fields like:

  • Email

  • Domain

  • Password

  • Tag (optional)

Step 3: Prepare Your CSV File

• Fill in your mailbox data following the format exactly.

• Double-check for typos and make sure all domains listed are already connected in Icemail.

Step 4: Upload the CSV & Click “Assign Mailboxes”

• Once your file is ready, upload it and hit “Assign Mailboxes.”

• Icemail will automatically generate and assign all listed mailboxes to their respective domains.

Mailboxes will now appear in your dashboard, ready to be used for warmup or cold outreach.

Pro Tips

• Use tags to organize mailboxes by campaign, SDR, or region.

• Enable auto warmup after mailbox creation to improve deliverability.

• If you're using third-party services (like Google or Microsoft), complete manual login after mailbox setup for proper verification.
