Do you want to convert Thunderbird to EML file? Are you looking for a perfect solution to export multiple Thunderbird Emails to EML files? If yes, then no need to worry. Here, we will discuss both the professional as well as the manual solution to carry out the conversion results.

Mozilla Thunderbird is one of the known Open-Source Email Client Applications which has been basically used for communication. It can be supported by different versions of Windows, Linux, and Mac OS users for sending and receiving emails. Supports both POP and IMAP Servers. And sometimes, users want to share, backup, and migrate their data in the form of EML file format.

Why do people usually prefer EML file format?


  • EML file consists of a single email message within a single file. So, it is good for those people who want to share particular or selective files at once.
  • It is safe and secure and if you share the file with someone else, then that user needs to open the file either in a particular Email Service or Email Client.
  • Also, the EML file stores the proper message including subject, recipients, To, Cc, date, sender name, multiple attachments, and hyperlinks also.
