Introduction

You can use Liquid templating in Kit to show specific pieces of email content to specific subscribers based on their tags or custom field values.

This tutorial will teach you how to combine the use of liquid templating and a cold subscriber re-engagement automation to display a re-engagement banner on all your broadcasts that is only visible to cold subscribers on your list. If cold subscribers don’t click the link in the banner, they will be unsubscribed from your list. This method is designed to work in conjunction with this cold subscriber cleaning automation, but you can simplify that automation by following the instructions later in this doc.

This will be broadly broken up into two main sections:

1. How to use Liquid in your emails to display the right content to the right subscribers.
2. How to use an automation to set the custom fields necessary for the Liquid to work and unsubscribe subscribers who don’t re-engage.

Using Liquid

The basic idea of Liquid

Kit uses Liquid templating for all kinds of customizations. Liquid is simple code you put in your emails that instructs Kit to render certain pieces of content for some subscribers and not for others.

The most common use of Liquid is to insert subscriber information, like their first name, into emails. For instance, if you insert the Liquid code {{ subscriber.first_name }} anywhere in an email or subject line, then it would be replaced with the subscriber’s first name when you send them an email. That line of Liquid tells Kit, “hey, when I send this email, I want you to grab the subscriber’s first name from their subscriber record and place it here.”

Content written in Kit’s email editor:

Hey {{ subscriber.first_name }},

I’m writing you an awesome newsletter right now. I hope you enjoy it!

How the content renders when you send it to a subscriber named Kyle:

Hey Kyle,

I’m writing you an awesome newsletter right now. I hope you enjoy it!

But you can do customizations much more complex than simple name insertions. You can create if/else statements that instruct Kit to display special content for subscribers based on their tags or custom field values.

The specific Liquid code you need for this strategy

<aside> <img src="/icons/copy_blue.svg" alt="/icons/copy_blue.svg" width="40px" /> Copy the Liquid into your email templates…

{% if subscriber.status contains "active" %}
{% elsif subscriber.status contains "cold" %}
[insert content here]
{% else %}
{% endif %}

</aside>

In our example, we want to place a banner on all our newsletter issues, but we want it to only be visible for subscribers who’s custom field, status , has the value cold.

This is what liquid looks like when you’re using it in the email editor. You can think of everything in the curly brackets as instructions for what content should be displayed for which subscribers.

In the example above, if the subscriber’s status field contains active, we don’t display anything. If their status field contains cold we display the banner. And if their status field contains anything else, we also display nothing.
