MailVault Reviews — Discover what people think of this product.

MailVault is a privacy-first desktop email client that keeps a complete, searchable copy of your messages on your own computer across macOS, Windows and Linux. Instead of trusting remote inbox storage, MailVault archives your mail as open, portable .eml files that remain accessible even if your provider or the app disappears.

With MailVault, you can search tens of thousands of emails in milliseconds, free up server space safely, and still keep every important message locally. It connects to Gmail, Outlook.com, Microsoft 365, iCloud, Yahoo and any IMAP inbox, then lets you archive and optionally delete from the server only after each message is fully checked and saved to your vault.

Advanced features (especially helpful for former Notion Mail users) include:

• Custom views that behave like inboxes, based on your own filters
• Per-message fields for stages, owners and follow-ups stored only on your machine
• Plain-language rules that auto-tag and organize incoming mail
• Automatic scheduled backups, Time Capsule snapshots and one-click manual backups
• Tracker detection and removal, plus built-in AI writing help to refine replies

MailVault never routes your email through third-party servers, doesn’t require a MailVault account, and avoids ads or data mining. It’s a long-term, local-first way to control, search and preserve your entire email history while staying independent of any single provider.
