Top 3 Methods to Import Gmail to Thunderbird

Now that you’re aware of the benefits of moving Gmail to Thunderbird, the next phase involves implementation. Users can choose the manual route or go for an automated professional tool. The tool saves both time and effort. Below, we’ll review both methods in detail.

Method 1: Manually Migrate Gmail to Thunderbird Using IMAP

The following method involves setting up your Gmail account in Mozilla Thunderbird using IMAP. By configuring IMAP syncing, it enables two-way syncing between Gmail and Thunderbird.

To import Gmail emails to the Thunderbird application, proceed with these steps:

Step 1: Configure IMAP in Gmail

  1. In the Gmail application, sign in with your Gmail account.
  2. On the top-right corner, click on Settings > See all settings.
  3. Then, select Forwarding and POP/IMAP tab, and under the IMAP Access section, select Enable IMAP.
  4. Click on Save Changes.

Step 2: Add Gmail Account in Thunderbird

  1. Launch Thunderbird and go to Menu > Account Settings > Account Actions > Add Mail Account.
  2. Now, enter your name, Gmail email address, and Password. Then, click Continue.
  3. Wait for some time. Thunderbird will automatically fetch IMAP configuration settings. 
  4. Once the settings are verified, click on Done.

Step 3: Access Gmail Emails in Thunderbird

  1. Thunderbird will prompt you to log in to your Gmail account.
  2. After you log in with your Gmail account, allow the necessary permissions.
  3. Thunderbird will start to sync your Gmail emails.

Limitations: The method involves multiple steps that might be confusing for a non-technical audience. It will not import Gmail labels, filters, and attachments. Since there is a two-way sync, deleting emails in Thunderbird will also get deleted in Gmail.

Method 2: Manually Import Gmail Mails to Thunderbird Using Google Takeout

This method involves two phases. The first phase involves exporting Gmail emails using Google Takeout in MBOX format. The second phase involves importing this MBOX file into Mozilla Thunderbird via an add-on. 

The following are the instructions to import your Gmails to Thunderbird:

Step 1: Export Gmail Emails Using Google Takeout

  1. First, visit Google Takeout.
  2. Deselect All and then select only Mail and check the box.
  3. Now, choose the File type & Size, Delivery Method, and the Frequency.
  4. Then, click on Create Export.
  5. Download and extract the .zip file. This will get downloaded in MBOX format.

Step 2: Import the MBOX File in Thunderbird

  1. Open Mozilla Thunderbird and head to Tools.
  2. Then, click on Add-ons and Themes, and Search ImportExportToolsNG.
  3. Install the add-on and restart Thunderbird.
  4. Right-click on Local Folders and choose ImportExportToolsNG > Import mbox file.
  5. Select Import directly one or more mbox files and click Ok.
  6. Now, browse and select the .mbox file and click on Open.

Limitations: This method involves only a one-time backup. Manually repeating the steps for a large volume of emails requires a lot of time. 

Method 3: Secure Way to Import Gmail to Thunderbird Using a Professional Tool

The Gmail Backup Tool is an all-in-one utility that makes Gmail backup and migration effortless. This powerful tool backs up complete Gmail mailbox data, including Inbox, Sent Items, and Drafts. It supports a wide range of export formats and allows direct moving to another email client. Smart features like selective folder backup, duplicate prevention, and attachment exclusion make it a perfect fit for both individuals and businesses. 

Simple steps to import Gmail emails to Thunderbird:

  1. Download and run the tool.
  2. Now, select Gmail (Backup Mails Only) and log in with your Gmail account credentials.
  3. After that, choose the folders that you want to export and click on the Next button.
  4. Select Save in File Format and choose MBOX.
  5. Afterwards, set the destination location to save the .mbox file. 
  6. Choose the desired additional features, like date range filter, and click Next to continue.
  7. Lastly, click the Convert button.

Importing Gmail to Thunderbird simplifies email management while ensuring an easy-to-use interface. The manual techniques, using IMAP and Google Takeout, do help effectively.
