Thunderbird is a free and open-source email client that’s lightweight and clean, and it was bought by Mozilla not too long ago. With a few easy-to-use tools, it also makes the management of emails a painless exercise.

What we like about this app is the customization options.

9. The Bat!

The Bat! is one of the most feature-packed and highly secure email apps for Windows PCs that you will find. Though this app has more features than almost any other app on this list, that’s also the reason it’s quite difficult to use for casual users. There’s a learning curve involved but once you master it, The Bat! could be useful and productive.

The app supports unlimited email accounts, even in its free plan, and you can easily manage all your emails from one place. Spike’s approach to email is a more conversational style, which means your emails will feel more like chat threads than boring old mail.

However, do note that this conversational, bubble design can be a tad annoying if you tend to send or receive long emails very frequently. Besides, Spike supports custom email templates, mentions (similar to Gmail), rules, and more. You also get unlimited searchable history in the paid plans of the app, as well as up to unlimited storage space, depending on which plan you opt for.
