8 Best Command-Line/Terminal Email Clients for Linux

Recently, I wrote an article covering the best email clients you can use on a Linux Desktop, all of the email clients in that list were graphical user interface (GUI) programs, but sometimes, users prefer to deal with email directly from the command-line.

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.

1. Mutt – Mail User Agent

Mutt is a small, lightweight yet powerful text-based email client for Unix-like operating systems. It is feature-rich and some of its remarkable features include:

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
• Uses Xapian to perform its major task, hence “not much”

• Also supports the Mutt integration script

5. Mu4e

Mu4e is an emacs-based email client that allows users to handle e-mails (such as searching, reading, replying, moving, and deleting) very efficiently. The basic idea is to configure an offline Imap client that allows syncing your local computer with a remote email server.

Features:

• Entirely search-based without any folders, only queries.
• Easy documentation with example configurations.
• User interface designed for speed, with fast keystrokes for common actions.
• Support for signing and encryption.
• Address auto-completion as per your existing messages.
• Extensible with available snippets or with your own code.

6. Aerc

Aerc is recommended as one of the best email clients that run on your terminal. It is free and open-source software that is very powerful and extensible and is perfect for discerning hackers.

Cone is another feature-rich text-based mail program and news reader that continuously handles numerous POP3, IMAP accounts, and local mail folders.

It also comes with advanced features for power users such as a built-in text editor for reading/editing emails, html support, address books, SSL/TLS, kview image viewer, and xpdf for displaying pdf files.

The above-listed command-line or terminal or text-based email clients are the best you can use on your Linux system, but many times, you can only find out the good features and performance attributes of an application after testing it.

Therefore, you can give all of them a try and choose which one to use, that is in case you are a command-line addict, who does not use GUIs so much.
