Search across every opened message by sender, subject, or text.
Open an EML file — right in your browser
EML files turn up as forwarded attachments, export bundles from webmail, and evidence exports — and a fresh Windows or macOS install often has nothing associated to open them. Mailward reads .eml files directly: the message body renders cleanly, attachments can be saved, and the full header chain is visible for anyone checking where a message really came from.
Multiple files can be opened together and searched as a set. Everything is parsed locally in a Web Worker, which matters because a message someone emailed you is exactly the kind of file you should not re-upload to a random website.
Before you trust a mail file to a website
Q. What is an .eml file?
A single email message saved as a standalone file in the standard MIME format — headers, body, and attachments included. Most mail clients can produce them; not every machine can open them.
Q. Can I see the message headers?
Yes — the full header chain is available, which is what you need to check a message's real origin or trace its Received: path.
Q. Is it safe to open a suspicious EML here?
Safer than opening it in your mail client: the message is parsed as data in a sandboxed browser page, nothing is executed, and the file never leaves your machine.
Q. Can I open many EML files at once?
Yes — drop a batch and browse them as a list, with search across all of them. Batch conversion to other formats is part of the Pro license.
