You can create custom share link tags using the tokens in any of the KickoffLabs emails. The new tokens include:

{% share_twitter_link Twitter %} – Custom twitter share link.
{% share_facebook_link Facebook %} –  Custom Facebook share link.
{% share_googleplus_link Google+ %} –  Custom Google+ share link.
{% share_linkedin_link LinkedIn %} – Custom LinkedIn share link.
{% share_email_link Email %} –  Custom Email share link.

You can also insert custom image buttons for these share links by replacing the text after the token with an image in the editor.

Here is an example of how to use these tags in emails:

custom_share_example

And this results in the following:

custome_share_working
