Why did you download it if you do not understand what it does? 

IncrediMail is a multimedia email program that allows you to customize your messages with colorful backgrounds, cartoons, emoticons, animations, fonts and sounds. The IncrediMail software is downloaded to your computer and provides the same function of incoming and outgoing email as any other regular email program
.
Features

Designed for the creative personality, IncrediMail offers a variety of bright, colorful backgrounds, unusual fonts and flash animations to spice up the usual black-and-white typed email. The software also features an e-card creator plus the ability to grab animations from the Internet or include personal spoken messages as an attachment.

Cost
The IncrediMail website offers a free download of the basic email software, which allows you to access free image and content galleries on the site. Further content is available for paid users. IncrediMail also sells add-on services, such as a spam filter and a personalized content creator.

Considerations
When installing, IncrediMail gives you the option of changing your browser's homepage and default search engine to MyStart; using the IncrediMail MyStart page and search engine generates revenue for the company and keeps the basic program free for users. To reject that change, click on the option of keeping your default homepage during installation.

Compatibility
IncrediMail is compatible with most web-based email, including Gmail, Yahoo and Hotmail, and accepts the HyperText Markup Language (HTML) format. It can also use the common Post Office Protocol (POP) and Internet Message Access Protocol (IMAP) email protocols, although you will need to know your basic POP information to set it up; this information is available from your Internet service provider (ISP).

Functionality
Although IncrediMail has lots of extra offerings to make email fun, it also has the basic features that make emails part of everyday life; the software has a built-in spellchecker, address book, and flexible option of sorting and filtering your inbox and outbox.
