A Quick Trick to open EML Files in Gmail

Another way to import EML files into Gmail is to convert the EML file to MBOX and Import .mbox file to Thunderbird via ImportExportTools Addon. For this, you need to follow certain steps:

  • Use .eml to MBOX converter software and create an MBOX file for all the .eml files.
  • Next, launch Thunderbird in which Gmail is configured. 
  • Navigate to Tools >> Add Ons to install the ImportExportTools.
  • Once the installation finishes, the software will force Thunderbird to restart.
  • After that, select the Gmail folder in which you want to move the MBOX file data.
  • Next, right-click on that Gmail folder and select ImportExportTools >> Import MBOX file.
  • Browse the MBOX file on your machine, and all the emails will get exported to the Gmail account.

This method is more reliable; and easy to perform because of two reasons:

  1. It is safer and 100% foolproof along with the assurance of no data loss. Also, the meta properties will remain intact when you export the EML files to your Gmail account.
  2. This method is useful for anyone who has an orphan MBOX file and likes to import it into a Gmail account manually.

However, if you do not have an MBOX file and want to move the other files like EML, then it is required to use a third-party solution to convert and save them to MBOX file format first. The same goes for any other folder format like Outlook to MBOX to open Outlook PST in Gmail.


If you have an old or orphaned EML file on your desktop and want to open it in your Gmail account, then the above solutions are perfect to accomplish the job in a hassle-free manner.
