If you have a website with your email address posted consider using a form instead that will email you the completed form. This will hide your email address from spam-bots crawling the web for email addresses. I recommend using a captcha on the form to keep bots from spamming you.
If you have a sales@ or support@ or other email address that must be posted make it difficult for the scrapers to find it. You can do this by using one of the tools below which will create a mailto link with the email address obfuscated.
