This is a nice plugin but it really requires a DOUBLE email field to prevent mistypes.
If people mistype their email address you can't contact them, as the address isn't correct.
Example:
Your email address is: ronsherman@hotmail.com
But you mistype: rpnsherman@hotmail.com
There is no way to contact you.
Every contact form has a double email field nowadays to prevent this issue.
