MacSonik IMAP Backup Tool - 2026 Pricing, Features, Reviews & Alternatives

MacSonik IMAP Backup Tool is an email archive and migration solution designed for Windows and Mac operating systems. The software caters to IT administrators, system integrators, and migration specialists responsible for managing email accounts using the IMAP protocol across services such as Gmail, Yahoo Mail, Office Three Sixty Five, AOL, Zoho Mail, and other compatible platforms. It enables backup of single or multiple mailboxes concurrently while preserving original folder hierarchies and email properties throughout conversion and transfer operations. Data integrity is maintained at every stage of the process.

The application supports conversion of IMAP emails into PST, PDF, MBOX, EML, EMLX, MSG, CSV, HTML, and TXT file formats. Supported migration pathways include Gmail, Office Three Sixty Five, IMAP accounts, and Google Workspace while retaining folder structures. Selective backup is facilitated through a date range filter that extracts emails within defined timeframes. A duplicate removal function filters messages based on criteria such as sender, recipient, subject, and message body. Additional configuration options allow exclusion of attachments, saving attachments as PDF files in separate folders, and splitting large PST files into user defined segments. Bulk operations are enabled through a CSV import feature that processes multiple account credentials and server settings. Preview functionality provides a view of mailbox contents with selection of specific folders before initiating the backup.

The software operates as a standalone application without dependencies on third party email client installations. It employs modern authentication protocols and requires administrator consent for organization wide resource access in Microsoft Three Sixty Five environments while ensuring secure login procedures. Compatibility spans recent Windows and Mac operating systems and recommends adequate memory for optimal performance. A server management feature permits deletion of emails from the source server after successful backup to free up mailbox storage. A free trial version enables the backup of up to fifty messages per folder for evaluation purposes. Full editions are available in home, corporate, and technical variants.
