eDiscovery Capabilities

Aid4Mail Investigator processes emails, images, and attachments 6x faster than the competition.


Your ability to find and collect email is near limitless. Search emails and attachments from nearly any source including delegated, shared, and public accounts. You can even extract MIME emails from any kind of file.

Before collection, search Gmail, Microsoft 365, Exchange, IMAP accounts and PST files to limit the scope. Filter down to what matters most and even recover double-deleted messages. With our proprietary Remote Authenticator, access accounts with the owner’s authorization but without needing their login details.


Aid4Mail has built its own search engine just for email. Use the same syntax as Gmail, Google Vault, and Microsoft 365 to find and filter emails 10x faster than e-discovery competitors. From simple Boolean and field searches, to synonyms and recursive searching, Investigator puts the power to cull data in your hands.

If that isn’t enough, Aid4Mail Enterprise can be installed on a server or flash drive so you can filter emails on any computer from anywhere.


Aid4Mail Investigator opens the door to even more conversion capabilities. Whether you convert the emails you’ve collected to PST, CSV, HTML, PDF, or one of our other many export options, you can ingest the email into your system any way you like.

When you convert with Aid4Mail, you can rest assured that every email message – header, body, metadata, and attachments – is preserved with the utmost accuracy.
