TL;DR: Back up Gmail, Outlook, Exchange, and IMAP accounts with encrypted, compressed archives and cloud mirroring. Mail Backup X Individual Edition is $49.99 for a lifetime license (MSRP $179). Every few months, there’s a new headline: leaked emails, hacked inboxes, and “missing” message histories that suddenly matter a lot. While most of us aren’t running governments or Fortune 500 companies, that doesn’t mean our inboxes are disposable. Email is where contracts live. License keys. Financial records. Two-factor resets. Years of personal and professional history. If you want security that goes beyond “it’s stored somewhere in my Gmail account,” you need Mail Backup X . Beyond simple backups, it handles archiving, migration, and restoration. You can import .pst, .ost, .mbox, .eml, and more, restore directly to a server account, or migrate mail to a new Office 365 account. Archives are highly compressed (saving up to 3x storage space) and searchable via a built-in viewer. For redundancy, mirror backups to Google Drive, OneDrive, Dropbox, pCloud, FTP, or a USB drive. Security-wise, it uses AES 256-bit encryption with your own private key—meaning your archives stay yours.
