As answered by people managing HardwareTestingPro and eM Client.
HardwareTestingPro's answer
HardwareTestingPro combines 77+ hardware diagnostic tools into a single browser-based platform - no installs, no sign-ups, and no ads getting in the way. From keyboard and mouse testing to monitor, mic, camera, and gamepad checks, everything runs instantly using your browser's built-in APIs, giving accurate real-time feedback in seconds.
HardwareTestingPro's answer
Unlike many hardware testing tools that require downloads or account creation, HardwareTestingPro works entirely in the browser with zero friction. It offers a wider range of tools (77+) in one place, a clean and fast interface, and results you can trust without worrying about privacy or bloatware.
HardwareTestingPro's answer
Gamers checking peripherals before matches, IT professionals troubleshooting hardware issues, remote workers setting up new equipment, and everyday users who want a quick way to confirm their keyboard, mouse, webcam, or mic is working properly.
HardwareTestingPro's answer
HardwareTestingPro was built out of frustration with clunky, ad-heavy hardware testing websites that required downloads for simple checks. The goal was to create a fast, free, no-nonsense tool that works instantly for anyone who needs to verify their hardware is functioning correctly.
HardwareTestingPro's answer
HardwareTestingPro is built using core web technologies - HTML, CSS, and vanilla JavaScript - along with native browser APIs (such as the Web Audio API, MediaDevices API, and Gamepad API) to power the real-time hardware testing tools directly in the browser, without relying on heavy frameworks or backend dependencies.

One point in eM Client’s favor is its free version. However, its features are pretty limited. For example, you can only use it with two email addresses, and the only customer support option is the user forum.
EM Client is a strong competitor of Outlook that has a easy-to-use interface. This application helps you to manage email, calendar, contacts, and tasks. It can be used for Windows and Mac.

Also, if you're also trying to use Xtra email in Microsoft Outlook, also expect problems. Outlook is also crap. There are other email application options. Em Client (emclient.com) is an excellent alternative to Outlook. Source: about 3 years ago
