[Plugin: Sharedaddy] Email is Not Working

I have activated the share by email option, however it is not going through when submitted. It allows me to enter the email address and when I hit submit, it says that the email has gone through, but it has not.

Any ideas?

I’m using on http://socialwoodlands.com.

Thanks,

Mark
