Dynamic sendgrid template for multiple items!

Ever wondered how to add multiple items in sendgrid template ?
For example you need to notify your platform users about list of courses available. Since the number of courses are dynamic you cannot create a static template for it.
Lets take an example of Grocery list template

The list of items is dynamic.

{
   "items" : [
      {
        "name" : "onion",
        "quantity": 5,
      },
      {
        "name" : "potato",
        "quantity": 5,
      },
      {
        "name" : "chilli",
        "quantity": 5,
      }

   ]
}

Inorder to iterate over the items of the nested array, sendgrid gives handlebar capbilities. Example code

{{#if items}}
  <h2 style="margin:10px 10px">Grocery items !</h2>
  {{#each items}}
    <div style="border:1px solid black;min-width:300px;min-height:50px;padding:10px 10px;margin:10px 10px">
        Got to buy {{this.name}}
    </div>

  {{/each}}
{{/if}}

You can include the similar code to iterate over items and produce a good marketing email templates.
