My colleague saved his Mac email data in EML format and gave me all the files so that I could access them on my computer. Now, I am wondering how to open these emails. I use Thunderbird which supports EML files. Can anyone suggest to me how to import EML files to Thunderbird? Thanks in advance.

Many users end up having a bulk of EML files with them that they want to open. Since Thunderbird is a free-to-use email application and also supports EML files, it is the top choice for users to read EML files.

But the problem is that users have to open EML files one by one, by clicking on that file from their original location. In the coming section, we will introduce you to manual & automated ways to import EML to Thunderbird with all attachments & Other attributes. So, let’s begin the post…

Thunderbird Import EML with Drag and Drop

  • Open Thunderbird and go to Local Folders.
  • Find the folder you want to import the EML files into.
  • Drag and drop the EML files from your file manager into Thunderbird.

This is one of the easiest methods to complete the process, but it has limitations. When you batch import EML to Thunderbird, various users have faced errors like Thunderbird running slow or not responding.

Use ImportExportTools to Add EML files to Thunderbird

  • Install the ImportExportTools add-on in Thunderbird.
  • Go to Tools > ImportExportTools > Import Messages.
  • Select the folder to import into, and choose “Import EML” as the file type.
  • Navigate to and select the EML files to import into Thunderbird.

The Import/Export NG add-on is compatible only with the latest versions of Thunderbird. Also, you can refer to this page if you encounter the ImportExportTools NG not working in Thunderbird.
