Property-Based Personalization

Property-based personalization is a method of inserting different values into messages for each user.

You can insert values such as name, tier, recently viewed products, and preferred category into text and links.

Basic Syntax

Hackle uses Liquid syntax.

{{ user_properties["name"] | default: "Customer" }}

If a value exists, it displays that value.

If there is no value, it displays the fallback text after default.

If needed, you can use event properties in the same way.

{{ event_properties["product_name"] | default: "A recommended product" }}

Where can I use it?

• Message title and body

• Button links and landing URLs

• Deep links and query parameters

You can easily add personalization text by pressing the {...} button on the right side of the text input field.

Examples

Message content

{{ user_properties["name"] | default: "Customer" }}, the product you saved is back in stock.

Link

https://example.com/cart?user_id={{ user_properties["user_id"] }}

Deep link

myapp://products/{{ user_properties["last_viewed_product_id"] }}

Be sure to set fallback text

Users without a property value occur more often than you might think.

For values that can look awkward when displayed, such as name, product name, and tier, it is good to include a default.

Check with preview

After verifying the personalization text you set in the popup, enter values in the user message preview.

You can immediately check the actual displayed text and links before sending.
