Assuming this is your personal website, a form with a captcha should suffice. Ensure the form limits the input to printable text and limit how often the form may be used by IP and globally. Captcha doesn't need to be a third party. It can be a simple math problem or a simple logic question or even "What is in the picture below?" and have a picture of a horse. Why a form? So people don't get your real email address and you have the option to only view the messages on your website at your leisure. Legit users will leak their contacts when they get malware on their system.
