Do you have a Pegasus mailbox that you want to move to Thunderbird? If yes, then in this blog, I am going to explain the different ways to migrate Pegasus Mail to Thunderbird.

Pegasus Mail and Thunderbird are two different email services, and Thunderbird does not support Pegasus Mail’s proprietary file format. So, is it possible to move the mailbox? Yes, there are indirect workarounds that can do your work. But why is there a need to transfer your mailbox? Below, I have mentioned common reasons.

Reasons to Transfer Pegasus Mail to Thunderbird

  • Pegasus Mail is one of the oldest email clients, and many people still use the software. However, it feels clunky and outdated when you are managing it with a modern email client like Thunderbird.
  • Thunderbird is a better option, as it offers two-way IMAP synchronization. So, whenever you read, delete, or organize your email from any device. It is instantly updated.
  • Pegasus Mail’s update cycle is slow, and it struggles with modern security protocols. Thunderbird is an active open-source platform that receives frequent security patches, bug fixes, updates, and data privacy standards.
  • The interface of Pegasus Mail is outdated and complex, whereas Thunderbird has a clean and intuitive layout that aligns with modern web browsers.
  • Thunderbird is used on multiple platforms, including Windows, macOS, and Linux. But Pegasus Mail is only tied to Windows.
  • The amazing thing about Thunderbird is that if you find any feature is missing, there is a range of add-ons and extensions available that you can install.

With these points, you understand why people are moving from Pegasus Mail. Now, let’s see the methods to convert Pegasus Mail to Thunderbird.

Copy Pegasus Mail to Thunderbird by IMAP Account Bridge

If your Pegasus email client is still working, then you can use an intermediate IMAP email account like Gmail, Outlook, etc., to act as a bridge to move your emails.

  1. First, go to Pegasus Mail and then the Tools option.
  2. Select Internet Options and set up your IMAP email account.
  3. Save it and restart your Pegasus account.
  4. In the folder list, you will see your IMAP account.
  5. Create another folder under your IMAP account. Then, drag and drop your Pegasus email directly to the folder that is created under the IMAP account.
  6. When the folder is fully synced and all your emails are uploaded. Open Thunderbird.
  7. Set up the same IMAP account in it. Wait for it to sync in Thunderbird and download all folders and messages.

This method needs an additional IMAP account to move your emails. However, there is another method that can directly transfer your mailbox.

Pegasus Mail vs Thunderbird – What’s the Difference

Many people know about Mozilla Thunderbird, but some of you may not be familiar with Pegasus Mail. To learn more about its features, I created a comparison table showing how it is different than Thunderbird.

Pegasus Mail Thunderbird
It is fully designed to run on a Windows-centric system. You can run Thunderbird on Windows, macOS, and Linux.
The interface of Pegasus Mail is retro and dialog-heavy, and looks like the Windows 95/98 era. The layout is modern and customizable, and the layout is similar to modern web browsers and desktop clients.
PMM, PMI, and CNM are the proprietary file formats. It supports the MBOX and EML file formats, common ways to store emails and import them.
Pegasus Mail offers you limited built-in extensions. Mozilla Thunderbird offers a wide variety of add-ons and extensions for free.
For managing contacts, the basic native address book is used, but you need an external tool for advanced scheduling. Calendar, task management, and a modern address book are integrated into Thunderbird.
Provide standard POP3 and IMAP, but you may face issues with modern authentication methods. It fully provides modern security protocols, OAuth2, and IMAP.
The license is free and provides an option for donation. It is free and open source software.

Concluding Words

Pegasus Mail is not up to the standard of today’s modern email services like Thunderbird. That’s why many are transferring their email. Because there is no native option available, your only option is to manually use an IMAP account as a bridge to migrate Pegasus Mail to Thunderbird. Along with it, you can use professional software, which is a much more reliable and direct option.
