Randomize or changing copy each time customer enters the same canvas

Hey SofiaZ 🙂 I would suggest to use Liquid as well, but instead of storage the 10 different text versions in an if function, you can create a content block with an JSON object and use a content block 😉. Let me explain how to do it:

First we have to create a JSON object like:

{
   "subjectline":{
      "0":{
         "text":"This is a great subject line"
      },
      "1":{
         "text":"This is another great subject line"
      }
   }
}

Continue this schema with your 10 different versions. Important: You have to start with 0 and please format the JSON object with a formatter.

Next, we create and save a content block and add some liquid, like this:

{% capture subjectElements %}

{
   "subjectline":{
      "0":{
         "text":"This is a great subject line"
      },
      "1":{
         "text":"This is another great subject line"
      }
   }
}

{% endcapture %}
{% assign object=subjectElements | json_parse %}

Now, we just have to add the following liquid in our communication to create a random number and select a random copy. The liquid below will generate a random number between 0-9 :

{% assign timeinsec = 'now' | date: "%s" %}
{% assign randomNumber = timeinsec | modulo: 10 %}

Now, we have to use this number to generate our random subject line with:

{{content_blocks.${random_text}}}
{% assign timeinsec = 'now' | date: "%s" %}
{% assign randomNumber = timeinsec | modulo: 10 | append: randomNumber %}
{{object.subjectline[randomNumber].text}}

Short explanation:

1. We add the content block, which we created 
2. We create a variable to define the current time in seconds
3. We create a random number based on the time variable and modulo it by 10. Furthermore, we also add the string filter 'append' to change the variable from an integer to a string.
4. We use our object with the random number to display the random text

What is the benefit behind this solution?

1. The content in your communication is shorter and more clearly arranged
2. You can always make changes easily in the content block

Let me know if this worked for you, or you have any questions!

Cheers!
