The supercharge feature uses your contact’s email address to find various online platforms to which your contact might belong. If your contact’s email address has an account through Facebook, Twitter, Google Plus, LinkedIn, etc. when you supercharge them, you will be given information about this contact so that you can connect with them across multiple platforms.
To supercharge a contact go to your Contacts page, find the contact you would like to supercharge, and click on their email address. This brings you to a page where you can see the contact’s information. On this page, please click the Supercharge button. Please keep in mind that if you click Supercharge and nothing happens- this most likely means that this contact does not belong to any online platforms under that specific email address.
