If you have left your E-mail Address over Websites/Forums/Blogs without taking necessary precautions, than your inbox will be bombarded with Spam E-mails on a daily basis.
But if still you want to share your E-mail address over Websites/Forums/Blogs, than one way is to use Disposable E-mail Addresses or more better option is to convert your E-mail Address into an Image!
Safe Mail is a simple yet effective service, that will convert your e-mail address into an image. Now share/host/upload this Image File containing your E-mail Address throughout the World Wide Web and Spambots can never figure out What actually your E-mail Address is.
See an Example Image of mine E-mail Address below:
The above format can never be read by Spambots and your E-mail Address will receive only clean/safe messages in future.
