Dynamic Email Template

Simple variable replacement can be achieved using the following syntax.

{"variables": [{
    "name": "firstName",
    "value": "John"
  }, {
    "name": "image",
    "value": "http://domain.com/image.gif"
  }, {
    "name": "link",
    "value": "https://smartsender.io"
  }]
}

<h1>Hi {{ firstName }},</h1>
<img src="{{ image }}">
<a href="{{ link }}">
  Go to SmartSender
</a>

Hello John

Go to SmartSender

Conditional syntax can be used to include/exclude email content based on data passed into API calls or stored in contact list.

{"variables": [ {
    "name":   "paidCustomer",
    "value":  false
  }, {
    "name":   "signupType",
    "value":  "referral"
}],

{% if paidCustomer %}
  Thanks for being a customer!
{% else %}
  Sign up today and get 30% off!
{% endif %}

{% if signupType == 'referral' %}
  <a href="https://smartsender.io">Refer your friends!</a>
{% endif %}

Most of your HTML needs can be met in our template editor. If you are using user-generated HTML and you need to pass raw HTML as a variable, you’ll need to escape it with Twig raw filters or autoescape tags.

{"variables": [ {
    "name":   "message",
    "value":  "<h4>Hello</h4><p>World</p>"
}],

{{ message|raw }}
<a href="https://smartsender.io">
</a>

Hello
World
Go to SmartSender

The following example illustrates how the round and format filters can be used to display numbers.

{"variables": [ {
  "name":   "price",
  "value":  9800.333
}]

<h4>Numbers:</h4>
<ul>
  <li>{{ price|round }}</li>
  <li>{{ price|round(1, 'floor') }}</li>
  <li>{{ price|number_format(2, '.', ',') }}</li>
  <li>{{ "$%.2f"|format(price) }}</li>
</ul>

Numbers:
9800
9800.3
9,800.33
$9800.33

The following example illustrates how to use Twig filters to achieve date formatting of both timestamps and ISO 8601 date strings.

{"variables": [ {
    "name":   "timestamp",
    "value":  "1539377301"
},{
    "name":   "isoDate",
    "value":  "2016-04-29T15:47:28+02:00"
},]

<h4>Flexible date formating</h4>
<p>Current date: {{ "now"|date("m/d/Y") }}</p>
<p>isoDate: {{ isoDate|date("D, F y") }}</p>
<p>timeStamp to custom:<
{{ timestamp|date('g:ia \o\n l jS F Y') }} </p>

Current date: 10/12/2018
