Tracking orders and sales from custom coded marketing email

I recently sent my first marketing email via Shopify’s Email app. When I view the report, I see that it did a good job tracking open and click through rates, but I’m concerned it’s not recognizing the links in the email as links to the website. The only link it recognized as being a link to the storefront was the unsubscribe link. That being the case, I’m not able to see the order and revenue data from the campaign. I did add this bit of code:

{{ unsubscribe_link }} {{ open_tracking_block }}
Is there something else I need to do to track revenue?
