EML file: How to open, view or edit.
An EML file is an easy way to save and store an email on a computer.
Are you wondering what a .eml file attachment is? An EML file is a plain text file format that can be saved to your device for both archival and document management purposes. Most EML files can be opened and saved to your computer, no matter your operating system. Learn more about EMLs, their pros and cons and how to open this file format.
EMLs are very easy to open if you use the correct email client, like Microsoft Outlook or Windows Live Mail. However, EMLs are adaptable to multiple clients and software if you use a few special techniques.
So, are you trying to open and view a .eml file? Read on to learn more about the properties of an EML file, the pros and cons of this file format and how to open one properly through multiple methods.
What is an EML file?
The acronym EML stands for email. It’s a file extension that shows an electronic mail message in plain text. The .eml file is a storage format for email messages and it is received and sent through RFC-822, the basic format and code for emails on the Internet.Think of it as a digital envelope that can be opened and read by different email software.
You can download an EML file to your computer, save it and view it with email clients like Microsoft Outlook, Windows Live Mail and Thunderbird. An EML file archives emails as a single file, preserving the original HTML format, headers and other metadata in the email conversation.
EMLs are used for backup and archiving, which can be useful for important conversations in a personal or professional setting. They allow users to control their archives and document management more effectively. EMLs are useful in legal cases, as they preserve the entire message and timestamps to verify the email’s authenticity. Users can also convert important documents and messages using a PDF converter to reduce file size or use password protection features to share sensitive information with others.
What’s included in an EML file?
An EML file is the plain text format of an email and is structured with a header and main body. The header will contain information like the sender and recipient’s email address, the subject line and the date and time of the email. The main body of the EML file is the actual email message script, including any hyperlinks and attachments.
How to open an EML file.
The best way to open a .eml file is to use an email programme compliant with RFC-822. If you have access to the Apple Mail email application, you can easily open an EML file on a Mac.
To open your .eml file, select the Mail application on your device, which is Apple Mail. Then, open the .eml file and download it to your Mac in your desired location. Make sure that you rename it to a relevant title so you can easily locate it again in the future.
Without Apple Mail, you can open and read EML files as plain text in a web browser, such as Safari, Firefox or Chrome, by dragging the file into the browser.
You can also use a text editor, such as Notepad, which is a standard method for opening and viewing EML files. Since EML files are saved in plain text format, it’s easy to change the .eml file extension to .txt. A .txt file is one of many different types of document files and is basically similar to viewing the email text as raw text. It’ll contain all the basic elements of the message without any hyperlinks, images or special formatting.
A Windows operating system provides the most native support for an EML file. You can open an EML file on Windows with an email client like Windows Mail or Microsoft Outlook. First, access your email client to locate the .eml file and double-click or right-click and then select Open with.Then, download any attachments in the file to view the proper email format or view any attached images. After opening the .eml file, download it and save it to your computer drive.
If you haven't got an email client, you can open and view an EML file as plain text through your web browser, such as Microsoft Edge or Internet Explorer, since the file is compatible with the browser MHT file format. Or, you can change the .eml file extension to .mht in your web browser, but the file may not display attachments or embedded images. You can also find a free EML file online tool to open and view it.
Users can edit an EML file with an email client or with a text editor like Notepad. Users can edit the content of the email message and details within the email header, like the subject line and recipients. However, a basic text editor may be limited in its complexity and ability to change several elements of the file. Most email clients will allow you to edit the contents of the EML, including the message, the recipients and sender information and possibly the attachments.
Pros and cons of .eml files.
EMLs are an efficient way to archive and save important files, but their tools and capabilities are limited.
Pros
Preserved email content.
EML files preserve your email content, so you don’t have to worry about losing important conversations or attachments. They’re useful for backing up or archiving email messages, which is useful for document management.
Easy to open.
Typically, users do not need additional software to open the file format since a wide range of email clients support EML files, making them portable and easy to open.
Security.
Since EML files preserve the original sender and recipient’s information, this is helpful for tracking email authenticity.
Cons
Limited functionality.
EML only supports basic text content and attachments and will not retain complex metadata such as email labels. So, they cannot utilise any advanced features, like tagging and sorting, which users may rely on for email organisation.
Larger file sizes.
If the email contains a lot of data or larger attachments, then the EML file may be unable to support the contents or use a lot of data on your computer.
Lacks compatibility.
Not all email programmes support EML files, so there may be issues with readability if using an unpopular or niche email client.
Security risk.
Always be cautious when opening any file, as it may contain malware or suspicious links. Only open EML files from senders you recognise.
Frequently Asked Questions.
You can open a .eml file on a mobile device by first downloading a .eml opener application.

EML files themselves are just a container for an email, but they're sometimes used to distribute phishing or malware. It's worth staying cautious — check for suspicious senders, scan the file with up-to-date antivirus software, and review the file name and size for anything unusual. If anything looks suspicious, avoid opening the file or clicking any links or attachments inside it, even if it appears to come from someone you recognise.
Converting an EML file to PDF can give you a more structured, widely compatible view of an email message. You can use an online EML-to-PDF conversion tool — search for one, upload the EML file following its instructions, and download the resulting PDF. Since these are third-party tools, avoid uploading anything highly sensitive unless you're confident in the tool's security.
You can also convert an existing email directly to PDF for archiving, and password-protect the PDF to add a layer of protection for sensitive data, such as a client's personal information.
Although MSG and EML are both file formats for storing and transferring email messages, they have different proprietary formats.

MSG contains mailbox details that are more specific to Outlook, such as Outlook calendar events and contacts, while EML is versatile for several platforms.
