Introdution: Email platforms change, but moving data continues to be a common obstacle. SquirrelMail, as a once common open-source webmail client, is now not comparable to what users expect. Conversely, Gmail’s storage, cross-device capability, and security are all much better than SquirrelMail. For professionals and organizations, thus, it has become important to transfer SquirrelMail to Gmail.

What is SquirrelMail?

SquirrelMail is a lightweight, open-source webmail client written in PHP. It provides a simple user experience of accessing the email message and sending them with an interface in a web browser using IMAP and SMTP protocols. The minimal design and low resource footprint of SquirrelMail made it popular in the early 2000s, but the open-source development of SquirrelMail is now outdated when compared to today’s standards and features. Moreover, it no longer receives continued updates. So, it is general for users to migrate SquirrelMail to Gmail. 

Why Move Email from SquirrelMail to Gmail?

The reasons for which users tend to perform this SquirrelMail to Gmail migration are:

  • Gmail is updated frequently, while SquirrelMail has not been actively developed in years. 
  • Gmail connects seamlessly with the other Google Workspace apps (Drive, Calendar, Meet) to collaboratively work with others easily. 
  • Google views emails from devices instantly without technical constraints from outdated SquirrelMail servers.
  • Gmail uses advanced spam filtering, phishing, and two-factor authentication as a means to mitigate data breaches.

There is a free manual solution for transfer through IMAP, and another is a professional tool that makes the process smoother and convenient. These are discussed as follows:
