What is an EML file?

An EML file is a standard email message file format defined by RFC 5322. It stores a single email message including headers (From, To, Subject, Date), body content (plain text and/or HTML), and attachments encoded as MIME parts. EML files are created by virtually every email client (Microsoft Outlook, Thunderbird, Apple Mail, and Gmail) when you export or save individual messages. They are the most universal way to store a single email and are ideal for archiving important messages individually.

FAQ

Common questions about EML files

How do I export EML files from Outlook?
In Outlook, you can drag emails from your inbox to a folder on your desktop, and each email saves as an .eml or .msg file. For batch exports, third-party tools or the Import/Export wizard can be used. Evermail support for .msg files is on the roadmap.
Can I upload thousands of EML files at once?
Yes. You can upload large batches of EML files in one operation. Evermail queues and processes them in the background and notifies you when indexing is complete.
Can I search inside EML file attachments?
Yes, for common attachment types including PDF, Word documents, Excel spreadsheets, and plain text files. Attachment indexing is available on Pro plans and above.
Is my data safe with Evermail?
Yes. Evermail is EU-hosted and GDPR compliant. Your emails are stored on Azure EU infrastructure and never leave the EU. You can choose from three security levels per mailbox, including client-side zero-access encryption.
