Please consider adding email as a social icon option under Appearance -> Theme Options -> Social
Hi @chrisjscott,
I hope you are well today and thank you for your feedback here.
We’ll consider adding email as a social icon in the future version of plugin.
In the meanwhile you can try achieving this by customizing the Sparkling theme function sparkling_social as described in the following reply.
