Your account is allotted a specific number of tests per month (default is 100) and each time you Run Test it is counted against that allotment. You can see the number of tests your account has and the number of tests you have used in the bottom-left corner of the page.
The functionality of Previewer is divided into four areas.
Renderings

- Web: Includes previews of what your message looks like in commonly used web browsers.
- Mobile: Includes previews of what your message looks like on all of the most popular mobile devices.
When you click on a rendering, a preview of your message as it would look in that client, browser, or device is shown in a new window. This gives you the opportunity to make sure your contacts receive a useful and well-formatted message from you, no matter how they access it.
