How can I get a "send a email"-Button in the gray "social and search widget"?

Hello Support-Team, in my (very nice, I'm loving it!) Catch Evolution Pro-Site, I don't find the way to put a "Send a Email"-Button in the "social and search widget" into the right sidebar. Do you have any Buttons which has the gray design as the social media buttons? How can I do this? Thank you for helping and sorry about my bad english :-) Tanja
