The way the email link functions is when it is clicked, it will open a blank email with your email address already inserted in the person's email client. For the email link to work properly, it depends on how your email client is configured on your machine or your visitor's machine. The default mail client will be the one that opens (or attempts to open).
Another option would be to use a contact form. This does not require the person's email client to be configured properly in this manner, and when they fill out the contact form and click "Submit" it will submit directly to your email.
Here is a link with more information on this option: Creating a Contact Form.
