As soon as you create a new project, you are asked to define the project settings. You can always change them when the project is not active (not scraping, not checking or sending messages). Just click on Tools→Project Settings.

The program will find you new websites where you can send your message to. It is requiring you to define keywords and search engines as in the screenshot below.

You can right click on the search engine selection to make selection easier (e.g. select by country, language…). Each item in the box with keywords means one search term to be used with search engines. You can input not only one word per item, but a phrase and can also use quotes to make the search more specific.

The first two boxes on that dialog define the words that get used to locate the sublink containing a contact form (in URL and/or as anchor text). You don't have to change that as it is already fine tuned by default.
