After backing up Gmail data using Google Takeout, the backup file is saved in MBOX format. However, many users struggle to open and view its contents. Below is a detailed guide to help you.
1. What Is MBOX Format?
MBOX is a common file format used for storing emails. To view its contents, you need to use specialized tools.

Step 1: Download and install Thunderbird from Mozilla’s official website (thunderbird.net).

Step 2: Open Thunderbird and create a new account (it can be a dummy email account).
Step 3: Install an MBOX file viewer add-on (e.g., “ImportExportTools NG”). Go to “Tools” –> “Add-ons” -> Search for and install this extension.
Step 4: Import the MBOX file into Thunderbird:
- Navigate to “Tools” > “ImportExportTools NG” > “Import mbox file”.

Step 5: View all emails in Thunderbird’s interface.
Method 2: Using an Online Google Takeout Viewer
- Visit websites that support MBOX file viewing, such as mailsdaddy.com or mboxviewer.com.

3. Important Notes
- Ensure that the software or tools you use are secure and reliable.
