Can mail size be broken down on thunderbird mail

Yes, Thunderbird does allow you to break down the size of your email messages. Here are a few ways to do it:

1. View > Message Body As > Plain Text: This will display the message body in plain text, which can help you see the size of the message more easily. You can also use the View > Message Body As > Source option to view the HTML source code of the message, which can also give you an idea of the size of the message.
2. Right-click on the message > View Source: This will open the message source code in a new window, where you can see the size of the message in the Content-Length header.
3. Use the "Size" column in the message list: You can add a column to the message list to display the size of each message. To do this, follow these steps:
   • Go to View > Message List Columns
   • Click on the Add button
   • Select Size from the list of available columns
   • Click OK to close the dialog box
   • The size of each message will now be displayed in the message list
4. Use a third-party add-on: There are several third-party add-ons available for Thunderbird that can help you analyze the size of your email messages. For example, the Message Size add-on can display the size of each message in the message list, and also provide detailed information about the size of each attachment.

I hope these suggestions help you break down the size of your email messages in Thunderbird!
