EML Viewer Pro is the single Windows app you need to view, search, print and convert .eml (RFC-822) formatted email files. It also lets you manage other email content, including Outlook .MSG, .PST, .MHT, .OST and Winmail.Dat files.

EML Viewer Pro organizes a folder of .EML files and displays them in a sortable list. You can then browse or search through hundreds (even thousands) of .EML files for those important emails. Using your favorite email client, such as Outlook, you can Reply, Reply All or Forward email messages.

Export your EML files to PDF and other useful formats, including MHT, HTML, CSV (Excel), JPG, GIF, TIF, BMP, and others.

Extract or Open File Attachments from .EML Files

Eml Viewer Pro makes it easy to access file attachments in .eml files. By clicking on the attachment in EmlViewer, users can either run the attachment in its native application (i/e open a .zip file in WinZip, or .pdf file in Adobe Reader), or they can extract the file to a directory of their choice.

The “Message” tab shows you the email message, rendering full html or RTF detail, so you see how it appeared in the email client.

Eml Viewer Pro provides access to the internet header information.

Search Your .eml Files

Eml Viewer Pro lets you search a directory of .eml files, and then easily browse the files that meet your search criteria.
