Contactify is a service which will generate an URL for your email address. You can then paste this URL in your public profile and others can contact you by visit it.
To use Contactify, you need to signup an account and activate through email. After that, you will be given an URL. When others visit the URL, they will get a contact form, but they will never know your real email address.
Contactify use CAPTCHA for the senders to reduce spam. This is a great idea as no one will know your real email address. Below is the form that others will get if they click the URL:
This looks like a good service, can greatly reduce spams received if u put your email address on your website.
@Kitkat: Yup, you can replace your email address with your link to Contactify, so that no one know your real email address.
Oh yeah, I bet this would cut down on spam email drastically. Neat service; it could be nice to keep your email address private.
