You can configure dynamic content of your emails sent out to your subscribers via the Email Configuration page under Settings. This article shows practical examples of template tags you can use to load dynamic relevant content into your email body. Email configuration page For the complete list of available tags, see Dynamic Email Liquid Tags.

​
Dynamic Tags

Tags are formatted with curly braces {{ }}. By using the correct variable name (e.g., {{plan.name}}) together with the curly braces, you can show relevant dynamic content to your customer. Depending on the email template, there are several categories of dynamic content available:
  • Plan: Current customer plan information like name and monthly_price
  • Project: Your company and product names
  • Subscription: Subscriber details like full_name and full_address
  • Extra fields: Optional extra fields added to your project like date of birth
The category tags look like: {{plan.name}}, {{subscription.full_name}}, {{extra_fields.birthday}} Available tags depend on the type of email that is being sent and are available under the plus sign in the email configuration edit box. Email template tag selector Some template tags require a bit of HTML to make your emails look professional.

​
Example: Cancellation URL

To configure a link like the URL to cancel a subscription, you can add some HTML to make a link more “human readable”: 
<a href={{subscription.cancellation_url}}>Cancel my subscription</a>
The {{subscription.cancellation_url}} is the dynamic tag used and “Cancel my subscription” is the text that will be displayed to your customer.

​
Example: Outstanding Invoices overview

You can display all outstanding invoices to your customer using the outstanding_invoices variable. To display all the invoices and create a separate line with the invoice data, use the {% %} braces (instead of just {{ }} for displaying data). The basic structure is: 
{% for invoice in outstanding_invoices %}
  ...display invoice data like {{invoice.amount}}...
{% endfor %}
Here’s a complete example to display outstanding invoices with their amount, current status, and a link to pay: 
<table width="100%">
{% for invoice in outstanding_invoices %}
  <tr>
    <td>{{invoice.number}}</td>
    <td>{{invoice.amount}}</td>
    <td>{{invoice.status}}</td>
    <td><a href="{{invoice.pay_now_url}}">Show invoice</a></td>
  </tr>
{% endfor %}
</table>

Example: Show text only after subscription is 90 days old

Sometimes you only want a piece of information to be available when a subscription has been running for some time. This can be useful for displaying extra services or motivating subscribers to re-order. In this example, we calculate if the subscription is at least 90 days old, then only show the information for those subscribers: 
{% assign contract_start = subscription.subscription_started_at | date: '%s' %}
{% assign three_months_ago = 'now' | date: '%s' | minus: 7776000 | date: '%s' %}

{% if three_months_ago > contract_start %}
  YES! You are eligible for our service upgrade
{% else %}
  Not yet a subscriber for three months
{% endif %}
The {% assign %} command creates a temporary variable and the pipe | puts this value through a “filter”. The code works as follows:
  • Set contract_start to the subscription start date, formatted as seconds since 1970 (the %s format)
  • Set three_months_ago to the current date/time, formatted as seconds from 1970, subtract 7,776,000 seconds (606024*90), and format it again as a date in seconds
  • The {% if three_months_ago > contract_start %} compares the two values and shows “yes” if the subscription is older than 90 days or “no” if younger
