How to convert Email to HTML (with message viewer)

Aid4Mail is the best Email to HTML converter software on the market. Unlike competing tools:

  • Aid4Mail offers full control over the HTML content.
  • Generates an HTML viewer to easily access and display messages in your browser.
  • Preserves email status information (unread, read, replied, …).

If you don’t have Aid4Mail yet, you can experiment with the free trial version or purchase a low-cost 2-week Aid4Mail Converter license.

Aid4Mail can convert email from many different formats such as EML or Mbox. It also excels in converting Outlook email to HTML (from formats like PST, MSG, OLM and OST). When converting from Outlook email formats to HTML, Aid4Mail does not need Outlook installed in order to complete the conversion. However, you will get better performance when Outlook is present.

When converting to the HTML format with Aid4Mail, emails can be viewed in any web browser and are rendered as they would be in email clients. You can filter emails by folder and by keywords in the date field, subject line and sender and recipient addresses.

Aid4Mail also enables you to fully customize the HTML data. Attachments are stored separately in their native format and are accessible from the email message through relative links in the HTML file.

Please follow the steps below to convert EML to HTML with Aid4Mail. This tutorial uses EML files but Aid4Mail can convert any of the supported email formats to HTML. For any setting that’s not specifically mentioned, you can either use the default (preset) value or consult the Aid4Mail 5 User Guide for details. You can open it from Aid4Mail by pressing the F1 key.

Step 1: Open Aid4Mail’s settings

EML to HTML session name

  1. In Aid4Mail, select the Settings tab.
  2. Update the Session name to so it describes for the task at hand. In this example, we will be converting John Doe’s EML files to a HTML so we’ve entered John Doe EML to HTML as the session name. When converting email to HTML, you can convert emails from any of the available Source formats.
  3. Below the session name there are three sections: Source, Target and Filter. Each can be displayed or hidden by selecting the +/- symbol next to the section heading. This tutorial requires them all to be displayed.

Step 2: Set EML files as your source

EML files as Source format

  1. In the Format list, select EML files.
  2. Set the Location of your EML files, either writing it directly in the field or by using the Select button to browse your file system. Set a single EML file, or a folder containing EML files, or a folder whose hierarchy (anywhere below it) contains EML files. For this example, we’ve set a folder called JohnDoe.
  3. Choose whether to Remove journaling envelope if your email files are journaled.

Step 3: Set HTML as your target

HTML as target format

  1. In the Format list, select HTML.
  2. Specify where you want your HTML files to be saved. You can write directly in the field or use the Select button to browse your file system.
  3. Select an option for the Folder structure of the exported mail. Usually you’ll want to keep it the same as the original, so choose Same as source folder structure.
  4. Select an option for the File name of the exported HTML files. For this example we selected Use a template to create a custom file naming template.
  5. For the custom File name template, {LocalMessageDate}-{Subject} was added. Each HTML file will have the emails date and subject as the file name. Select Insert to see all available template options.
  6. Select an option for the Email header configuration. You can select one of the default options in the drop-down list or you can create your own by using the Add button. Aid4Mail allows you to fully customize which items of information from the emails you want added to the HTML files. As shown below, there are 95+ items that can be selected. For this example, we are using Email with basic header.HTML Email header configuration editor
  7. Create HTML index option. When on, Aid4Mail will create an index for your target HTML files. The index acts as a web viewer, containing a list of all target emails created. The list can be sorted and filtered by keywords to locate specific messages. Any email selected in the list will be displayed in the lower half of the page, allowing you to view and examine it.

Step 4: Set your filter (optional)

Filter settings

  1. Under Folder filtering, pick Folder selection. Your EML files folder structure will appear in the box below.
  2. Select the folders you want Aid4Mail to process. The others will be skipped.

Step 5: Run your EML to HTML conversion

Select the Run button or Session > Run from the menu. Aid4Mail will convert your chosen EML files to HTML. It will automatically open the Progress tab so you can monitor what’s going on. Once finished, you will find full reports in the Progress log and, if relevant, the Error log.

Step 6: Open the HTML viewer (HTML index file)

You can do this by opening the index.html file located in the target location. The index.html file will open in your default web browser. You can now view all of the emails from the EML to HTML conversion. You can also use the folder selection drop down and filtering options find specific emails easier.
