How do I link my social media accounts so they are accurate on my autoresponder and emails?

When you open your email in the editor, simply highlight the icon as you would any text. A pop-up men will immediately appear, and on the far left (under Paragraph) you will see a chain-link icon. Click that and a dialogue box will appear where you can add your personalised link for that icon. Unfortunately, there is no central place where you can set these once and use them forever, but you can create a template and save them in that.
