You connect your email accounts and email clients. Mail Archiver starts pulling in your email — including years of existing correspondence — and builds a complete archive on your own machine.
No configuration ritual, no learning curve, no changes to the way you work. You keep using email exactly as you always have. Mail Archiver runs alongside, quietly, and the archive grows with every email you send and receive from that point forward.
The first time you search for a three-year-old email and find it in four seconds — that's the moment the question stops being "do I need this" and becomes "why didn't I start sooner."
Mail Archiver is for you if email has ever mattered after the fact. An agreement referenced six months later. A project that stretched across two years and three client contacts. A conversation your lawyer asked you to produce.
Mail Archiver is also for you if you simply have years of correspondence you don't want to lose — and you'd rather not trust a platform to hold it for you indefinitely.
Mail Archiver is not for you if:
Mail Archiver does one thing. If that one thing is what you need, it will do it better than anything else you'll find.
Every feature in Mail Archiver exists to prevent a specific kind of loss.
Mail Archiver will never modify an email you've archived. Not to clean it up, not to save space, not to make it more readable. What you archived in 2020 is byte-for-byte identical to what you'll open in 2032.
Mail Archiver will never summarize, interpret, or analyze your correspondence. No AI reading your emails. No "insights." No quiet decisions made on your behalf about what matters and what doesn't.
Mail Archiver will never delete or alter anything without an explicit action from you. Every irreversible step requires your decision, and nothing happens in the background that you didn't authorize.
Mail Archiver preserves the record. Mail Archiver does not decide what the record means. That's yours.
"Mail Archiver X creates rotating backup sets, runs smoothly in the background, and my restore tests worked flawlessly. I feel safer now."— Stefan H.
Most people never run a restore test on their backups. They assume everything is fine until the day they discover it wasn't. Stefan ran the test. It worked. That's the whole point — not just that the archive exists, but that you can actually get back into it when you need to.
Email programs get discontinued. Providers change their systems. File formats fall out of fashion. Mail Archiver is built with all of that in mind.
The archive format is designed for long-term readability, not for whatever is convenient today. Stability and compatibility are not afterthoughts — they are the design brief. An archive you create this week should open without friction in 2035, regardless of what happens to the software landscape between now and then.
Most software is optimized for acquisition. Mail Archiver is optimized for the decade after you buy it.
Download the trial, connect one account, and watch the archive build with your actual correspondence.
You don't need to read more documentation to know whether this fits. Connect Mail Archiver to your own email and see what it does — that's the only evaluation that matters.
If Mail Archiver does what you need, you'll know within the first session. If it doesn't, you've lost nothing.
The archive that exists five years from now is the one you start today.
Mail Archiver X creates a complete, searchable archive of your email. The archives are stored locally, are independent of your mail provider, and can be exported in open formats.
This page explains exactly how that works.
| Step | What Happens | What It Means |
|---|---|---|
| 1. Connect | Mail Archiver X reads your email from Mail, Outlook, Thunderbird, Postbox, and IMAP accounts including Gmail and iCloud. | No manual exporting required. |
| 2. Archive | Emails are copied into a local archive database. | Your history becomes independent of your email provider. |
| 3. Access | You search and view emails inside the archive. | Fast retrieval, even years later. |
The archive does not need to remain on your internal disk. Many users store their archive on an external hard drive to free space while maintaining full search and access.
Mail Archiver can store emails in its internal database or directly in MBOX or PDF format. MBOX and PDF can also be used for export.
The goal is simple: your archive should remain usable, portable, and under your control over time.
| Format | What it's for | What you get |
|---|---|---|
| Internal Database | Primary working archive |
|
| Storage and readable export |
|
|
| MBOX | Storage and portable export |
|
If you export later (PDF or MBOX), the goal remains the same: portability without surprise.
A Mail Archiver X archive is designed for long-term readability and completeness. It preserves both content and context without rewriting your emails.
Your archive is meant to be faithful and stable over time.
Mail Archiver provides a dedicated viewer for browsing archived email.
The interface is designed for clarity and long-term access, not for managing daily inbox workflows.
Mail Archiver is available in two versions, depending on how the archive is accessed.
| Standard Edition: Mail Archiver X | Server Edition: Mail Archiver X Pro + Pro Admin | |
|---|---|---|
| Deployment | Local installation (macOS) | Server-based installation |
| Designed for | Single-user archives, including professional and high-volume use | Accessing the same archive from multiple computers and/or multiple users |
| Archive location | Archive stored locally on the user’s Mac or chosen storage (e.g., external drive) | Archive stored on a central server |
| Server installation | No server installation required | The server must be installed, configured, and managed by the user (or their IT/admin) |
| Access model | One archive accessed by one user |
A single user can access the same archive from multiple client computers simultaneously. Multiple users can access a shared archive. |
| Visibility control | — | Users see only their own emails unless user groups are explicitly defined |
