Artistry, Ltd. review for Constant Contact: Email & SMS

Really wondering: what is the point of this app? We use Constant Contact for all of our business emails and now that we have a B2B Shopify website, the app was a no-brainer. However, it doesn't do very simple things that are actually CRITICAL. For example, the price in an email does not update when a price is updated on the website. Also, you can toggle through variant images but you cannot toggle and select the specific variant's price. Additionally, it is not accurately tracking our sales as attributed to the emails. Am I missing something? I would love some help or some extra information about how this is supposed to work. It just seems like so many vitally important features are missing.
