Automated Marketing Thank You Email Social Media Link Error

I am attempting to set up an automated thank you email for customers who have placed an order with my store. I am editing the email template provided to customize it for my store. I can change the text on the button to the name of the social media website, but I cannot link to my social media accounts. The only links that prove available are pages in my store. Thus, the email template code is not working in the manner that would be assumed by the text above and on the buttons prior to any attempts at customization. I would really like to be able to use the template for what it was designed for with the social media links, please advise.
