Sending email from web page

On a web page under "Contact us" there is an email address in blue.
When I click on this email address I receive the following message:
"Could not perform this operation because the default mail client is not
properly installed."
Is this a problem with my computer or the web page?
If it is my computer, how do I correct it?
