Email button missing

Hi there,

I’ve been using the Acurax floating icons plugin for a while and it’s great. So thanks for that.
However, the email button is missing. Is there any way to customise my icons to add this one using CSS or something else?
I’m pretty new to wordpress and coding so if somebody wants to help, it’d be great!

here is my site: http://welchfishmongers.co.uk/

thanks a lot.

Benedicte
