Back in Stock Email example

<h1>{{event.title_incl_variant}} is back in stock!</h1>
<p>Hi {{event.customer_name}}, great news! The item you were waiting for is now available at {{event.shop_name}}.</p>

<div class="product-info">
  <img src="{{event.image_url}}" alt="{{event.title_incl_variant}}">

  <p>Price: {{event.price}} {{event.currency}}</p>
  <p>By: {{event.vendor}}</p>
</div>

<a href="{{event.checkout_link}}" class="cta-button">Buy Now</a>

<p><a href="{{event.unsubscribe_link}}">Unsubscribe</a> from future alerts</p>

Back in Stock SMS example

🎉 {{event.title_incl_variant}} is back in stock at {{event.shop_name}}!

Get yours now for {{event.product_price}} {{event.product_currency}}: {{event.purchase_link}}

Reminder Email/SMS templates

For reminder notifications (when {{event.is_reminder}} is true), you might want to use different messaging:

Email reminder example

<h1>Still interested in {{event.title_incl_variant}}?</h1>
<p>Hi {{event.customer_name}}, this is a friendly reminder that {{event.title_incl_variant}} is still available at {{event.shop_name}}.</p>

<p>Don't wait too long - stock is limited!</p>

<a href="{{event.checkout_link}}" class="cta-button">Get It Now</a>

SMS reminder example

👋 {{event.customer_name}}, {{event.title_incl_variant}} is still available! Limited stock remaining: {{event.purchase_link}}

Best practices

For email templates

Always provide an unsubscribe link using {{event.unsubscribe_link}}
Use conditional logic with {{event.is_reminder}} to create different messaging for initial alerts vs. reminders
Personalize with customer name ({{event.customer_name}}) for better engagement

For SMS templates

Focus on the most important information (product name, price, link)
Include the purchase link prominently

By leveraging these STOQ-provided variables effectively, you can create dynamic, personalized Back in Stock notifications that drive conversions and keep your customers engaged.
