    Output options

    No file is ever uploaded — conversion happens on this page.

    Works with exports from Gmail / Takeout · Outlook · Apple Mail · Thunderbird
    How it works

    From mailbox to exhibit in three steps

    No software to install, no account to create. The converter is the page you're on.

    01

    Export your emails

    Drag messages out of Outlook (.msg), download from Gmail (.eml), or export a whole mailbox with Google Takeout (.mbox). Our guides cover every client.

    02

    Convert locally

    Parsing and PDF generation run in your browser. Each PDF preserves the full header block, body and an attachment manifest — the parts that authenticate an email.

    03

    File it

    Download individual PDFs, or a single merged exhibit in date order with Bates numbers and a SHA-256 integrity manifest. Ready for court, HR or records.

    Before & after

    The same email — as your client exports it, and as you file it

    Bob,

    Per my email of February 12, the lease requires the deposit returned within 30 days of move-out. It has now been 47 days. If the $2,400 is not returned by March 15, I will file in small claims court.

    I've attached the move-out inspection photos and the certified mail receipt.

    Alice

    Security by architecture

    Built for documents that can't take a detour

    Upload-based converters hold your files on their servers — often for 24 hours, in unknown jurisdictions. CourtMail was built the opposite way: the conversion engine ships to your browser, and your emails stay on your machine. Load the page, disconnect from the internet, and convert offline.

    Zero upload, by architecture

    There is no server that receives files. Parsing and PDF generation are client-side code.

    Headers preserved verbatim

    From, To, Cc, Date and Message-ID — the fields courts and opposing counsel check first.

    SHA-256 integrity manifest

    Each PDF is hashed at conversion. Any later alteration is detectable by recomputing the hash.

    Bates numbering built in

    Sequential exhibit stamps with your prefix, the way productions are actually cited.

    Common questions

    Answers before you file

    Are the PDFs acceptable for court filings?

    The PDFs preserve the complete header block (From, To, Cc, Date, Message-ID), the message body, and a manifest of attachments — the elements opposing counsel and courts look for when authenticating email evidence. The full version adds Bates numbering and a SHA-256 integrity manifest documenting that each PDF is the unaltered output of conversion. Admissibility is always case- and jurisdiction-specific; this tool prepares the documents, your attorney makes the call. CourtMail is software, not legal advice.

    Do my emails get uploaded?

    No. Parsing and PDF generation run entirely in your browser. You can load this page, disconnect from the internet, and convert offline. There is no server that ever sees your files — by design, because lease disputes, HR complaints and custody cases shouldn't sit in a stranger's cloud for 24 hours the way upload-based converters retain them.

    How do I get my emails as files in the first place?

    Gmail: Google Takeout exports your whole mailbox as one .mbox file. Outlook (desktop): drag messages from the message list to your desktop to get .msg files. Apple Mail: select messages, File → Save As, or export a mailbox as .mbox. Thunderbird: right-click a folder → ImportExportTools. Step-by-step walkthroughs are in our guides.

    What does "1,000 conversions" mean?

    Each email converted counts as one credit, whether it arrives as a single .eml or as one message inside a 2 GB mbox. 1,000 covers a typical contested-matter email production several times over. Credits never expire, and there's no subscription to cancel.
