Are you looking for a method to export Thunderbird to HTML so as to view EML messages of Thunderbird in different web browsers? This blog is dedicated to all the readers who wish to have an instant solution to change Thunderbird email to HTML formatting.

Hello there,

I have been using Mozilla Thunderbird as the mail email client for a while now. One of my projects deals with web designing in which I have to utilize the data present in emails into several web pages for my clients. So, for completing this assignment, I intend to change some of my Thunderbird MBOX email messages in HTML format so that I can use them for templates. I started my research on finding the solution who was having the same problem as I do. After playing around with a lot of searches, I have figured out how to fix it: by converting Thunderbird emails to HTML code. Then, I manually tried to change Thunderbird messages to HTML code. Here’s the attached screenshot.

But again, I got frustrated because the metadata like Subject, CC, BCC were missing. What to do now? I precisely want to export Thunderbird to HTML so that I can customize my messages with fonts, colors, word processing options of my choice. Is there any available automatic solution for changing the Thunderbird mailing list thread (having 350+ mails) to HTML? If yes, then please suggest! It would be great if the Thunderbird export be well readable, formatted and email attributes remain the same. I use Windows 10 OS if that matters. Eagerly waiting for your response!!
