Secret Decoder Ring

The JavaScript FORM above will encode your e-mail address for you. Type in your current e-mail address and hit the "Encode" button, select the result, and paste it into your webpage. In other words, if your current webpage contains:
< A HREF ="mailto:garyathome@pacbell.net">garyathome@pacbell.net </ A >

Then you should replace it with:
< A HREF ="mailto:%67%61%72%79%61%74%68%6F%6D%65%40%70%61%63%62%65%6C%6C%2E%6E%65%74" > garyathome@pacbell.net</ A>

Note: This encoding trick works in all browsers I know of.

Mailto format
The mailto URL contains only the e-mail address according to the official spec.

Some browsers support additional fields after the address.
For example, <a href="mailto:john@example.com?subject=Syzzygy"> creates an address that when clicked on will not only launch an e-mail box but will also automatically fill in the Subject: field. This was supported by the original Mosaic and adopted by Netscape. However, Microsoft didn't support it until MSIE v5.
