Different Approaches to Export Thunderbird Emails to Gmail

Manually Migrate Mozilla Thunderbird to Gmail

This approach uses the IMAP protocol to sync emails from both Thunderbird and Gmail. It also ensures that the original folder structure is maintained.

The following are the steps to begin the process:

Step 1: Enable IMAP in Gmail Account

1. First, open Gmail and log in with your Gmail account credentials.
2. After that, head to Settings > See all Settings > Forwarding and POP/IMAP tab.
3. Then, under the IMAP Access, Enable IMAP. 

Step 2: Add a Gmail Account to Thunderbird

1. Open Thunderbird and then go to Account Settings > Account Actions > Add Mail Account.
2. Next, enter the Gmail account credentials and select IMAP.
3. After the emails appear in Thunderbird, select the email messages you want to export to Gmail.
4. Then, drag and drop them into the Gmail folder.

Limitations: Some messages or attachments may not upload correctly due to size restrictions or server timeouts. Occasionally, Thunderbird may skip certain emails or attachments because of server limits. Some emails or attachments may not upload due to size constraints or server interruptions. 

Transfer Thunderbird Emails to Gmail by Forwarding Method

Forwarding emails is a simple manual way to get Thunderbird messages into Gmail. You can forward individual messages or batches of messages to your Gmail account. 

These are the manual steps to initiate the export process:

1. Launch Thunderbird and open the folder containing the desired email messages.
2. Now, select one or more messages you wish to forward. 
3. Then, right-click the selected emails and choose Forward As > Inline/Attachments.
4. In the recipient field, add the Gmail address where you want to forward the emails.
5. After that, hit Send.

Limitations: Manually forwarding hundreds or thousands of emails can be extremely time-consuming. Forwarded emails do not retain Thunderbird’s folder organization; they appear in the inbox or a label chosen in Gmail. Inline forwarding removes headers; attachments preserve them but are less readable.
