Exporting Thunderbird email addresses to CSV file can be done manually, though the process can be time-consuming and somewhat technical for non-experts. To export manually, open Thunderbird and go to the *Address Book*. Select the address book you want to export, then click on *Tools > Export*. In the export dialog, choose the destination folder, select “Comma Separated (CSV)” as the file format, and save the file. However, this method only works for addresses stored in the Thunderbird address book—not for email addresses found within message content, CC/BCC fields, or other folders. Extracting these requires going through emails individually, which is tedious and prone to error.
To overcome these limitations, using a specialized tool like Cigati Email Address Extractor Tool is highly recommended. This utility simplifies the process by scanning entire Thunderbird profiles, including inboxes, sent folders, and attachments, to extract all email addresses automatically. It supports bulk extraction, filters duplicates, and saves the output in CSV format with ease. This not only saves time but also ensures comprehensive and accurate extraction of all relevant email addresses from your Thunderbird client. For users seeking a quick and efficient solution, the Cigati tool is a reliable and user-friendly choice.
