Meet the contenders

Whether you're a freelancer, small business owner, or corporate executive, there's an email app for you. We're here to help you decide.

Let's look at how these two email apps stack up against each other.

Twobird

Twobird is a unique app that approaches email management as a to-do list. By combining your messages, calendar events, tasks, and notes into an agenda-like workspace, the cross-platform Twobird treats your email as one component of your overall productivity. This way, you only need one app to manage your daily tasks.

Thunderbird

Thunderbird is a free, open-source, cross-platform email client that’s managed by a core staff and a community of volunteer developers. Although the app is already quite robust, there are optional add-ons that you can install to enhance its functionality. So, when it comes to cost-effective email client apps, you can’t go wrong with free—there are no separate paid versions.
