Cigati Thunderbird Backup Tool - 2026 Pricing, Features, Reviews & Alternatives

Cigati Thunderbird Backup Tool is an email backup and migration application designed to extract, preserve, and transfer data from Mozilla Thunderbird mailbox installations. The software enables systematic archival of email communications and supports migration to alternative platforms. IT administrators and email system managers benefit from the application’s capacity to maintain data integrity and preserve folder structures during conversion operations.

The application exports Thunderbird mailboxes into multiple file formats including PST, MSG, EML, EMLX, PDF, CSV, HTML, plain text, DOC, and DOCX. A preview feature displays message content and associated attachments prior to processing. The tool allows selection of specific messages or folders for backup or migration and supports date range filtering for targeted data extraction. A duplicate removal function identifies and eliminates redundant items. Users may exclude attachment files when only message bodies are required. Custom naming conventions for output files and options to preserve the source folder hierarchy are available. A save-in-source-folder mode enables storage of output files within the original directory.

The tool operates as a standalone Windows application and supports the latest Windows versions and earlier releases. The software requires installation of Mozilla Thunderbird for mailbox access and profile detection. Antivirus software must be disabled or whitelisted to prevent conflicts during operation. Log files are stored in the user’s Documents folder and temporary files in the local Temp directory. Cloud migration to services that require authentication mandates user sign-in to generate access tokens.

A demonstration version permits preview operations and processing of up to fifty messages per folder. The licensed edition removes these limits and grants full access to all backup and migration features. Technical support is available to licensed users.
