Email basics
What is an EML file?
An EML file is a saved email message. It usually stores the original message headers, sender and recipient information, subject, date, plain-text content, HTML content, inline images and attachments. Because it is based on standard email message structure, it is widely used for archiving, support tickets, legal records, invoices, receipts and exported conversations.
What does an EML file contain?
A typical EML file can include the visible message body and hidden technical metadata. That metadata may include the sender address, recipient address, subject line, delivery route, message ID, content type, MIME boundaries and attachment information. Some messages include both a plain-text version and an HTML version so email clients can choose the best display mode.
Which apps use EML files?
Many email clients can read or export EML files, including Thunderbird, Apple Mail, Windows Mail and several webmail or helpdesk systems. Outlook often uses MSG as its native saved-message format, but EML export may be available depending on the version, account type or workflow.
Why convert EML to HTML?
HTML is easier to open in a browser, share with non-technical users and archive with a readable visual layout. Converting EML to HTML can also help when you want to review a saved email without importing it back into an email client. If the email includes inline images or attachments, a ZIP export keeps the converted HTML and related files together.
Are EML files private?
EML files often contain personal or confidential information. EML2HTML Studio processes files locally in your browser, which means the conversion does not require uploading the email to a conversion server. You should still be careful before sharing the converted HTML, because the exported file may include names, email addresses, message content and links.
