For this reason, there is also a need to highlight some of the best text-based email clients that you can use on your Linux system.

Although command-line email clients do not offer as exceptional features as their GUI counterparts, they do offer to present some great and powerful message-handling components.

In this review, we shall exclusively dive into looking at some of the best command-line email clients for Linux and the list is as follows.

Please note, all these below email clients can be installed using default package managers such as yum, dnf, or apt as per your Linux system distribution.

4. Notmuch

Notmuch is a fast, powerful, global-search and tag-based email system that you can use in your Linux text editors or terminal. Its development was highly influenced by Sup, and it offers performance enhancement to several Sup features.

It is not much of an email client, therefore, it does not receive emails or send messages but simply allows users to search quickly through a collection of emails. You can think of it as a library interface to extend an email program for fast, global, and tag-based email searching functionality.

Notmuch has the following notable features:

  • Does not support IMAP or POP3 protocols
  • No mail composer
  • Supports tags and fast search
  • No user interface
