Need help: Back in Stock Email will be sent out to recipients after its DOI confirmation only

Solving my own question. Epic success 😁

Jokes aside, my logical thinking was strong enough. This is the solution:

We modified the code, so that a signup to Back in Stock would not only set a metric but also the affiliation to a list. You can find our code here:
 

<script src="https://a.klaviyo.com/media/js/onsite/onsite.js"></script>
<script>
    var klaviyo = klaviyo || [];
    klaviyo.init({
      account: "XXXXXX",
      list: 'XXXXXX',
      platform: "shopify"
    });
    klaviyo.enable("backinstock",{ 
    trigger: {
      product_page_text: "📧 Notify me!",
      product_page_class: "btn",
      product_page_text_align: "center",
      product_page_margin: "0px",
      replace_anchor: false
    },
    modal: {
      headline: "📧 {product_name}",
      body_content: "<span style='font-size: 16px;'>Ja, ich möchte per Mail informiert werden, sobald das hier vorgestellte Produkt wieder verfügbar ist.",
      email_field_label: "Deine Email",
      button_label: "Benachrichtigung erhalten",
      subscription_success_label: "Du bist dabei! Wir sagen dir Bescheid, wenn wir nicht mehr sold out sind.",
      footer_content: "<span style='font-size: 12px;'>Meine oben eingetragene Mailadresse wird ausschließlich für die Verfügbarkeitsbenachrichtigung verwendet und nicht an Dritte weitergegeben. Meine Einwilligung kann ich jederzeit mit Wirkung für die Zukunft widerrufen. Die <a href='URL TO YOUR DATA PRIVACY SITE' target='_blank'>Datenschutzerklärung</a> mit weiteren Details habe ich zur Kenntnis genommen.",
      font_family: '"YOUR FONT",light;',
      drop_background_color: "#000",
      background_color: "#fff",
      text_color: "#222",
      button_text_color: "#252525",
      button_background_color: "#YOUR BUTTON CI",
      close_button_color: "#ccc",
      error_background_color: "#fcd6d7",
      error_text_color: "#C72E2F",
      success_background_color: "#d3efcd",
      success_text_color: "#1B9500",
      newsletter_subscribe_label: "Ja, ich möchte eine Back-in-Stock-Nachricht erhalten.",
      subscribe_checked: false
    }
  });
</script>

So the person is added to the list which you can set up using any list ID. Cool backtest: I recommend setting up a Back in Stock List and a Back in Stock Segment (triggered by metric), the amount of recipients should always be the same, if its not you have an error. 

The list MUST have DOI set in the list settings. I also recommend to adapt the DOI and success pages in that specific list, so that the wording is not contributed to “newsletter” but to “back in stock notification”.

If code is ready and list is set up you can modify the back in Stock Flow.

You can use Klaviyos “Back in Stock Flow - Standard” but you must set up a flow filter. Feel free to steal mine:

 

Hope that helps,
