How to Transfer Emails from Google Takeout to Thunderbird in Simple Steps

Google offers Takeout as a service that lets one export their emails, attachments, and folder hierarchy whenever one needs a complete backup of their mailbox. It makes it possible for you to download your Gmail data and, thus, store it locally, as well as transfer it to another platform. This has led a good number of users perplexed as to how one can transfer Google Takeout data to the well-known open-source email client, like tranfer Google Takeout to Thunderbird, import Google Takeout to Outlook, ect.. This guide aims to present users who managed to download their Google Takeout files and wish to read and manage them on Thunderbird with the most convenient and secure procedure available.

What Are Google Takeout and Thunderbird?

Let me clarify the two services:

• International Mail Export (IME) is a free Google Takeout service wherein data is exported from your Google account. The binder and folder compress in a ZIP or TGZ format. Each Gmail export is organized into MBOX files which include a compilation of all emails. 

• Mozilla Thunderbird is free and cross platform. Thunderbird is able to import emails from Google Takeout because it supports the MBOX format. 

The MBOX file is compatible with Thunderbird which means you are able to import Google Takeout emails directly with no complicated procedures. 

What are the advantages of importing Google Takeout to Thunderbird?

The emails can be transferred to Thunderbird for the following reasons:

• Anytime Reading - when you previously had to search for emails on Google and had to be connected to the internet all the time, this is no longer the case. 

• Improved Mail Management - with the use of Thunderbird, you are able to use advanced filters to de-clutter your mailbox. 

• Gmail Data Preservation - backup every Gmail account on your computer or an external drive for the added measure of security. 

• Gmail account Migration - in order to preserve all emails after migrating from Gmail, the account must be imported.

Step 1: Download Your Gmail Data with Google Takeout

1. Go to Google Takeout.

2. Click Deselect all, then select Mail to export only your emails.

3. Choose your preferred file type (ZIP is easiest) and size.

4. Click Create Export. Google will prepare the archive and email you a download link.

When the export is ready, download the file and save it to your computer.

Step 2: Extract the MBOX File

• Locate the downloaded archive (for example, takeout.zip).

• Unzip it to access the Mail folder.

• Inside you’ll find a file such as All Mail.mbox. This is the key file you will import into Thunderbird.

Step 3: Prepare Thunderbird for Import

1. Install the latest version of Mozilla Thunderbird if it isn’t already on your computer.

2. Open Thunderbird and click the three-line menu in the top right.

3. Choose Add-ons and Themes, search for ImportExportTools NG, and click Add to Thunderbird.

4. Restart Thunderbird to activate the add-on.

This free extension makes it possible to import MBOX files directly, which is essential for our task.

Step 4: Import Google Takeout Data to Thunderbird Email

1. Under Local Folders in Thunderbird's left pane, right-click and choose New Folder. For easy identification, you may call this folder Google Takeout Backup.

2. Right-click that folder and select ImportExportTools NG > Import MBOX File.

3. Select Import directly one or more MBOX files, and then locate and select the MBOX file you downloaded.

4. Click Open. All emails along with attachments and folder structure will be imported.

Thunderbird will arrange the imported emails in the same way they appear in your Gmail.

Helpful Tips for a Smooth Migration

• Determine File Size: MBOX files can measure many gigabytes, so account for extra time during import.

• Maintain Copies: ‘Takeout’ archives are best stored on external hard disks or cloud-based systems.

• Employ Filters and Labels: During and after the upload, Thunderbird can automatically or manually assign messages based on time, sender, or user as specialized.

Using A Specialized Application 

Specialized MBOX tools can perform bulk MBOX file imports, split MBOX files without losing folder structure, and facilitate folder hierarchy and structure retention, among other things. Such software can support those who manage many Gmail accounts or very large archives, as manual methods can be time consuming. These tools are designed for large scale email work, helping IT organizations and companies with thousands of emails streamline the process.

Advantages of This Method

Compliance with each of the above steps will: 

• Preserve the entire email: Attachments, the formatting of the email, and the metadata, including the date and the name of the sender, are untouched.

• No email data will be lost: There is no chance of partial imports and corrupted messages. 

• In enhanced mobility: Your emails can now be easily transferred, backed up, or transported.
