Aid4Mail 5 “Early Access” now available!

Rewritten from the ground up with a new UI and up to 6x faster, powerful filtering with Gmail/O365 search operators, integrated Python scripting, simplified licensing, and lots more.

Aid4Mail 5 is finally here! And with a 20% Early Access discount*.

Developing quality software takes time. We’ve worked hard to implement many of the features you requested. In addition, we’ve added new and unique capabilities to provide high-quality results quickly! We’ve also made our licensing terms more flexible, removing many former restrictions. More on that below.

First, what do we mean by “Early Access”? It’s not Alpha or Beta software. Aid4Mail 5 Early Access has been extensively tested and is safe to use in a live production environment.

The Early Access version already meets most users’ requirements. While it has many new features, it does not yet include everything we’ve planned. OST, OLM and Apple Mail (EMLX) support, for example. New features will be gradually added during the Early Access phase and, after careful testing, made available through frequent updates.

Aid4Mail 5 comes in three editions: Converter, Investigator, Enterprise. Converter is limited to email conversion. It’s very fast! Investigator adds powerful email filtering and Python scripting. Enterprise includes all the Investigator features, and can be installed on a server or run from a USB drive.

Read on to find which best suits your needs.

Aid4Mail Converter

If all you need is to download and convert email, then Aid4Mail Converter is for you. It’s an ideal solution for preparing mail for ingestion into archiving, eDiscovery and forensic tools. What’s more, you can use it to process unlimited mail stores, whether in-house or from external sources.

This new edition is very fast—up to 6 times faster than its predecessor! Remarkable considering Aid4Mail 4 is already one of the fastest email converters on the market. And this speed gain is without sacrificing accuracy.

Incremental processing has also been significantly improved. In some cases, it’s over 100x faster than in Aid4Mail 4! It’s simple to use and makes it a breeze to continue a prior conversion where you left off. Or to capture any new mail received since last time.

And that’s not all. Aid4Mail can now access Gmail and Outlook 365 through their native APIs—a much more secure and efficient method. We’ve also developed a free remote authentication tool. It enables anyone to grant temporary access to their Office 365 or Gmail account. This can be done securely, without providing login credentials, and without an installation of Aid4Mail.

Although Aid4Mail 5 doesn’t yet offer the full range of formats available in version 4, it already includes the most popular: PST and MSG files, Outlook profiles, Outlook 365, Gmail, secure IMAP for cloud-based services like, Mozilla Thunderbird, Maildir, mbox and EML. Convert between formats or transfer messages in the same format, for example from PST to PST.

Other features not mentioned above
  • Reliably download large IMAP accounts through effective error recovery protocol.
  • Secure access to Gmail, Office 365, and IMAP through OAuth 2.
  • Accurately restore the folder structure from Google Takeout files.
  • Export emails as searchable PDF files with linked attachments.
  • Convert to HTML and display emails in browser through included viewer.
  • Plain text, CSV, TSV and XML target formats.
  • Extract email attachments.

Before deciding whether Aid4Mail Converter is right for you, please take a look at the next two options. Their advanced features may provide real benefits to your work.

Aid4Mail Investigator

If your work involves email forensics or eDiscovery, or you need powerful email search and filter capabilities, then Aid4Mail Investigator is ideal. It includes all the benefits of Aid4Mail Converter with additional tools to find relevant emails. It also accelerates email processing even further.

The new filtering capabilities in Aid4Mail Investigator far exceed those in Aid4Mail 4. And they’re more user-friendly, offering the same email search operators as Gmail, Google Vault and Office 365. You can now search any part of an email including attachments and deeply embedded contents. Even file metadata like EXIF and IPTC information contained in pictures.

Suppose you’re searching for text in a PDF file that’s contained within a ZIP archive, attached to an email that is itself the attachment of another email. Aid4Mail 5 will find it!

You’ll find helpful filter operators to skip duplicates, emails originating from mailing lists, bulk mail and notifications—essential tools to cull redundant and irrelevant emails before review.

If you need more advanced search features, Aid4Mail gives you full control through Python scripting. Extract and search text from images using Python OCR modules. Or use Python image analysis to detect nudity in photos. The possibilities are endless…

Aid4Mail Investigator also supports native Gmail and Office 365 filtering, handled at the server end by Google or Microsoft. As a result, only emails matching the search criteria are downloaded by Aid4Mail. This feature alone can result in significant time and cost savings.

Aid4Mail Investigator - Multiple sessions running at the same time

Last but not least, you can speed up processing even further by running multiple conversion engines simultaneously. These can either be totally independent conversions, or share the same source or target, or both. For example, you can merge emails from multiple sources into a single PST file. Or split a single source file into multiple target files. Or apply multiple search criteria to a single mail store, saving the results in different folders within the same PST. All at the same time.

Other features not mentioned above
  • Reorganize emails by account.
  • Configure Bates stamping format.
  • Access and restore unpurged mail.
  • Add missing metadata to target emails.
  • Access Public and Shared folders and Delegate accounts.
  • Use word proximity operators, wildcards, and regular expressions in your searches.
  • Customize target folder and file names using Python scripts.

Before deciding whether Aid4Mail Investigator is the right choice, please take a look at our Enterprise edition below. Depending on your set up, it may be more cost effective and adapt better to your work environment.

Aid4Mail Enterprise

The most advanced and complete email processing tool we’ve ever developed. Aid4Mail Enterprise has all the features you need for email conversion and archiving, email migration, email forensics and eDiscovery. It is well suited to large-scale email processing in medium to large organizations.

Aid4Mail Enterprise combines all the benefits of Aid4Mail Converter and Investigator together with flexible licensing that make it a very cost-effective solution.

Aid4Mail Enterprise - Multiple sessions settings

An Aid4Mail Enterprise license is tied to a computer, server, or USB drive instead of a seat. This makes it available to any number of users in your company. You can run Aid4Mail Enterprise from a server or networked computer or from a shareable USB flash/SSD drive. This makes it ideal as a portable solution in the field as well as in the lab.

With Aid4Mail Enterprise, you get these additional email formats:

A) Source formats
  • Google Vault (zipped MBOX files)
  • Mimecast (zipped EML SJF files)
  • Proofpoint (zipped EML files)
B) Target formats
  • Office 365 and MS Exchange (via MAPI)
  • Gmail (via Google API or IMAP)
  • Dovecot, Courier, Zimbra, … (via IMAP)

You also gain access to a command-line interface (CLI). This allows you to seamlessly integrate the Aid4Mail engine directly into your workflow. Use it in scripts and batch files to automate email processing. Or create your own user interface to limit the features available to your end users.

What Makes Aid4Mail Better than its Competitors?

Fookes Software has been developing software since 1990. Our first email-processing tool was launched in 1999 and Aid4Mail followed in 2005. So our experience in handling email spans over two decades. That’s considerably longer than most of our competitors.

All core functionality in Aid4Mail is developed in-house. This means that key features are tightly integrated and optimized for speed. We are in full control of our code including key components like email parsing and conversion, the filtering engine and its search syntax, MAPI access to Outlook accounts, and even the IMAP protocol used to connect with services like Yahoo! Mail and AOL.

Most of our competitors rely heavily on code and software libraries (DLLs) from third parties. Even for their key features! One product, for example, installs 663 third-party DLLs. This means they’re depending on the know-how of other companies instead of their own. As a result, our competitors have little or no control over code quality and security, performance optimization and bug fixes.

Aid4Mail is Swiss Made. It meets the high-quality standards that Switzerland is famous for.
