Want to search inside EML files but don’t know how to? No problem. This blog will guide you on how to search EML files for keywords, specific content in email body, and multiple email files without opening them. We will also cover how advanced search can help users to find email content more specifically.

However, searching via EML files can be challenging when you have multiple downloaded emails. As opening every message individually using CTRL+F may work, but it might be ineffective for thousands of EML files when searching for keywords or specific email body content. Therefore, we have covered several possible ways to search in EML files, that include searching manually, via Windows search, PowerShell, an email client like Outlook, and dedicated EML searching software.

Let’s begin searching within email files quickly with this article.

What is EML File Search?

EML file search simply means finding something in your email message. It can be any specific data within single or multiple EML files. One can look for these:

  1. Any particular keyword or phrase.
  2. Subjects
  3. Sender or Recipients
  4. CC or BCC
  5. Date
  6. Body of Email
  7. Attachments
  8. Any Specific Combination

For example: Suppose you have multiple saved EML files and want to find some specific keyword within message. Then it will be easier and faster than opening each email individually.

Different Ways to Search Inside EML Files

In this following section, we have listed several ways to advanced search in EML files, and it may depend on number of messages and type of data you require to look for.

  • Payment

This approach works well only when you are looking in single or few email messages. However, it becomes very challenging when trying on multiple EML files, as it will require lot of time and human effort.

Using Email Client Search

The user can consider this technique for searching data inside email body, as one has to import EML files into email application that supports EML format.

You can search these in your email client such as:

  • Sender
  • Date
  • Email Address
  • Recipients
  • Subject

It can be helpful only if your EML files are well structured or managed within application. However, if you need to inspect or analyse EML files, then you must use dedicated software mentioned below.

  2. Go to Folder that contains EML files.

  2. To automate searching process
  3. Search multiple EML files in bulk
