No HTML compose is the only reason I don't switch to it. We're not in 1980 anymore.
I think most people are using gmail accounts or outlook accounts to access their emails. Claws supports Oauth2 to access said accounts but the implementation, is a complete PAIN.
I can only realistically recommend something like this if your email provider is not forcing Oauth2.
I would like for the devs to get to work into making the experience of setting up an account with oauth as painless as thunderbird.
Betterbird, a soft fork of Mozilla Thunderbird, improves user experience with advanced features, bug fixes, security patches, and multi-row descriptions similar to Outlook. Compatible with multiple platforms and can be used alongside Thunderbird, sharing the same profile.
Betterbird does everything that Thunderbird does (it's a soft fork), while improving bugs and features.
Because it's a soft fork, it retains the security implementations of Thunderbird.
Thunderbird actually implements many of the bug fixes created by Betterbird, but at a much slower pace.
has more features than thunderbird
Betterbird is actively updated by a previous Thunderbird developer and is a fully compatible fork of Thunderbird which fixes some outstanding bugs. My add-ons like keepassxc-mail work fine!
Web-browser, advanced e-mail, newsgroup and feed client, IRC chat, and HTML editing in one application. Itis built on the open source Mozilla Gecko engine, the same code which underlies Thunderbird and is the base for the Firefox browser.
SeaMonkey is both a WEB BROWSER and EMAIL CLIENT. It's the successor of Mozilla Application Suite or Netscape Communicator, resp. Further it includes also a news client program, an HTML editor (SeaMonkey Composer) and an IRC client (ChatZilla).
It has all of Thunderbird's features and many more.
Unfortunately doesn't support synchronization with CardDAV address books.

Clean interface, much faster than Thunderbird. One touch unsubcribe is a nice touch and adding new accounts is a breeze
Mailbird is missing most of the features which Thunderbird offers, like encryption and plugins

As a Firefox user, I have tried to love Thunderbird but it just can't compete with Outlook, IMHO.
Not open source, not privacy-focused, no Linux support
no linux support, not portable, not free, and now its new version is electron app only

Mutt is a small but very powerful text-based mail client for Unix operating systems. Some of its features are: color support, message threading, MIME support (including RFC2047 support for encoded headers), PGP/MIME (RFC2015), various features to support mailing lists, including...
Thunderbird users want a GUI mail application. Mutt is a command line mail application. They are both good and both popular, but very much apples and oranges.
Mutt's a great email client for your terminal, not a GUI app like Thunderbird.

Despite the style, Claws is super fast and allow you to programs it with Perl and Python which is great for marketing automation.
