Simple, forever email journaling

Low cost, immutable email journaling, archiving and storage

What is Journaling?

Journaling is the capture and storage of every email message that transits your email system; including internal messages between your staff.

Emails are stored and locked-away in a secure storage space – and are kept forever.

Why do organisations like yours journal their emails?


Emails can easily be deleted. When a dispute arises – be certain that you can recall the original email intact – no matter how long ago. 


Fulfil your obligations of data capture and retention. This is required in many regulated and un-regulated industries and makes for a proactive legal strategy. 



See what’s moving in and out of your organisation before anyone has a chance to alter it. Search and filter through all of your emails from one page.


When you need proof of what emails were sent or received, beyond any doubt. Cryptographically-verifiable ledgers provided by MailStones are the last word.

Faster Access

Instead of waiting days for your Helpdesk, access and download that critical email (or those critical 1,000 emails) in less than 10 seconds.

Better than Backup

Backup is periodical, isn’t indelible, fails, and almost certainly does not retain data indefinitely.  What if you need an email sent/received that was deleted before the backup was taken? MailStones will have it ready for you in 10 seconds with just a few clicks.


Retrieve emails in seconds.

Browse, search, filter, retrieve and bulk retrieve any email within a few clicks.

Undeleteable storage. Security at every level.

Three storage locations

Email data stored in three separate datacentres, providing 99.999999999% durability.

Data Encryption

Data at MailStones is encrypted both at rest and in transit. 

Indelible storage

The storage used for your data is immutable. But don’t take our word for it; AWS’s Compliance Mode object lock feature has been assessed for SEC Rule 17a-4(f), FINRA Rule 4511, and CFTC Regulation 1.31 by an independent third party.

Frequent Questions

How much does it cost? Why so much less than other providers?

After a 7-day trial, it costs $1.60AUD per mailbox, per month. 

We think that most organisations would benefit from our service, so we want it to be as affordable as possible. Similar solutions cost the same (or more) than your mailbox licenses - and we don't think this is correct.

As such, our system is efficiently written using modern application techniques. Combined with AWS's server-less processing and storage capabilities, we are able to deliver at scale, with low costs.

How does it work?

We capture, catalogue, store, and index every message as it moves in, out, or around your email system.

How long does it take to set up?

Your account is ready in less than one minute once you have registered.

What changes are required on my email system?

When you register, we allocate you a capture address. Simply configure your email system to send journal reports to this capture address.

How can I access my emails?

Our system catalogues and stores your emails within 30 seconds, after which it is available for search and retrieval. Single emails can be downloaded immediately, and bulk emails are downloadable with a link which takes less than a few minutes to create (even for 10,000s of 1000's of emails). 

What happens to my data if I want to close my account?

You can close your account at any time. You can export all of your data using our Dashboard, without needing to contact us. Just download download your metadata in CSV or Excel format, and you can download your email raw data by using the Bulk Download feature on your Dashboard.

Where is my data stored?

 Your data is stored in a region of your choice between: Sydney (Asia Pac), London (UK), US East (Virginia), US West (Oregon), Frankfurt (Europe), Saul Paulo (South America).

Who can access my emails?

Only the account-holder, through their MFA-enabled account.

Can I pay in any currency?

Our payments are processed in Australian Dollars, and will be converted to your local currency by your financial institution.

Can I cancel at any time?

Yes. We will cancel the service at the end of your current billing month. We will then retain data for 7 days beyond this, after which time the data will be removed.

Can I pay by invoice, instead of by Credit Card?

Yes, but we charge an invoice fee of $15.

I take email backups, why do I need MailStones?

A backup is a periodic copy of data. Data can be altered before the backup runs, and backups aren't usually kept forever. Backups are also deletable, and prone to failure. MailStones on the other hand keeps a separate copy, as soon as the message is sent or received.

Is Journaling the same as archiving?

No. Archiving involves moving a message from its native location to somewhere else. Messages in archives can be altered or deleted.
