Cigati Proton Mail Export Tool - 2026 Pricing, Features, Reviews & Alternatives

Cigati Proton Mail Export Tool is an email export application that enables extraction and preservation of messages from ProtonMail accounts through IMAP connectivity. It facilitates migration to multiple file formats and cloud-based platforms including PST, MBOX, PDF, and Microsoft Office 365. The tool addresses the requirements of system administrators and technical professionals who need to preserve email data integrity across diverse environments. It supports both individual and batch processing workflows through credential and server configuration files in comma separated value format.

The application preserves folder hierarchy and email metadata including sender, recipient, subject, and timestamps during the export process. It provides a date range filter to restrict operations to message sets within a specified timeframe. Duplicate message elimination is available based on field comparisons such as subject, content, and address data fields. An option to exclude attachments from exported items allows the separation of message text from embedded files. The server cleanup feature can remove messages from the source account upon successful export.

The export engine uses IMAP protocol support to connect to ProtonMail and other compatible mail services through authenticated sessions. The tool maintains the integrity of message properties and supports migration to various target clients by requiring only valid account credentials. Modern authentication workflows are supported for environments that require administrative approval and user sign in for security token generation. There is no file size limitation for individual mailboxes during export operations.

The application runs on Windows eleven, Windows ten, Windows eight point one, Windows eight, Windows seven, Windows Vista, and Windows XP. It requires a processor operating at approximately three gigahertz or above, eight gigabyte of memory, and five hundred megabyte of storage for program installation with additional space determined by data volume. A trial version enables evaluation with a restriction of up to fifty messages per folder. No direct integration with external application programming interfaces is provided beyond built-in mail client and format support.
